Chrysler-Dodge-Mitsubishi 2.5L Misfiring, Pinging, Detonation, Stalling, No Start, P0171 Code

[@rhkips]

Experience gave you a leg up on this one, but could we get there without the experience, only using diagnostic logic? Yes. P0171, watch fuel trims: Coinciding with misfire event, but clearly reactive, not causative. P0171 invalid for direction on misfire. Problem intermittent, related to heat: Rules out compression/exhaust. Scope ignition and fuel injectors. Do we need to look at MAP in this case? No. Known vacuum leak; MAP data invalid to start with, and vacuum leak is constant, while problem is intermittent. Idle is being controlled despite vacuum leak, points to functioning MAP sensor. Ignition and FI scoping reveals intermittent random firing events: Immediately points towards cam/crank. Scope, find, analyze, done! For those just starting out, don't let your lack of experience hold you back. Have a solid diagnostic process, and don't deviate from it. People WILL give you a hard time, call you slow, say you're wasting your time; just ignore it. Have your process, do your thing, and never second-guess yourself unless the data you get from your process tells you to. Speed will come in time, but until then, people will start to notice your low comeback rate. And any time you hear someone say "Oh man, I don't want that job!" Jump up and say you'll take it. Doesn't matter what vehicle it is, the laws of physics and fundamentals of electrical and electronic design don't care what make of car it is, or what system they're affecting, and neither should you. :)

This may be the best write up I've ever read. I feel like you are reading my mind. Thank you so much! I'm pinning this comment

[@2secondslater]

This thought process is all good and well if a fault is occuring consistently or occurs in a short time frame and you are able to gather the data such as "only occurs when warm or hot". The reality is that most people doing diagnosis are either stretched for time (why else would Danner get Scanner Danner in?) or under pressure from an employer to make a quick diagnosis or not have the right equipment or the product knowledge and then come to conclusions that are incorrect because of those numerous external factors. I have been in the trade for almost 30 years now and still make some incorrect calls, not because of lack of knowledge, but because sometimes the process isn't that straight forward and you have work building up and a customer that has limited funds to pay for the time, for instance, and the best you can do is make a call based on experience. I am a foreman at a small shop now that specialises in the hard to fix faults and have a team that is learning new things and don't pressure them too much beyond their skill levels and help when they are stumped and can't figure it out. "No one problem is ever the same"

[@ralfsautomotive]

@@2secondslater Well put!

[@2secondslater]

PS. I also forgot that sometimes a customer fails to tell you the history on the vehicle and what has been done previously, making diagnosis harder, as there are processes you need to undertake given lack of information... This is especially relevant in what we do at the shop I work at as we get a majority of vehicles that come from other shops or dealers or used car companies.

[@rhkips]

Absolutely correct. Every diagnosis--and every situation--is unique. That's exactly why having solid fundamental knowledge and a sound process is so important. What we see Paul doing here, taking an hour and thirteen minutes to call a crank sensor, is about teaching. In the real world, this is a 10-15 minute diagnosis, with most of that waiting for the car to warm up enough to fault. If you're billing for an hour of diagnostic time, you're still way ahead of the curve, and you're not risking losing time in a comeback for an educated guess. Keep in mind also that setting expectations with your customer is a big part of the repair process; especially with intermittent faults. Easy to say when you're in a small shop or self-employed, but there's nothing that says you can't work with your service writer(s) in a dealership or large-scale shop environment to help them work with your customers, and to communicate customer concerns to you. It'll never be perfect, but routine processes make things easier, and consistent. Consistency builds experience. Experience lets you make those knee-jerk educated guesses. :)

Awesome video! For the guys without the daily experience to already know the crank sensor is a pull-down design, we'd have to unplug the crank sensor to find the 5v on the signal wire. And then we're already at the crank sensor harness and I'd probably just start scoping from there. So we'd be forced to do the test you were able to avoid. Also watching the pid for cam sync going in / out made me think come on Chrysler, you should be throwing some sort of sync code, crank sensor or misfire code, something more than a lean code! And to the whole Danner family, your videos are well appreciated.

ScannerDanner Can a faulty crank shaft position sensor throw a P0351 coil code? It was a crank no start. I took spark plug No. 1 off of a Jeep 4.0 and I got it to start. I put the plug back on and the code went away. After it warmed up, it started to run rich. Check engine code p0171 popped up. I have already replaced the crankshaft sensor about a year ago from o’Reillys.

[@frugalprepper]

This video is full of gold nuggets of info. Some people watch to try to match up the symptoms and figure out what part they need to change if it happens to them. Others of us watch to see the diagnostic process. Know the Theory, observe the problem, formulate a hypothesis and test the hypothesis. Keep on teaching and take all the time you want. I will probably never run across that car with that engine, but I learned a lot of useful information for all troubleshooting on all cars.

Thank you for showing that diagram and taking the time as well, the two words you printed with "Shorted signal" got me to understand what you meant with an open in the wire. Because my mind was stuck on the fact that open / break in wire = short circuit or intermittent short circuit, and that would pull it down in your case. But when you said open as in missing and no short, it all clicked in, thank you for taking that extra time.

[@tysonrinker5958]

Scanner danner is so right. I have been a automotive tech for a little under a decade now and I have seen so many techs read scanner then replace a sensor or part. Which may work some of the time or hell even work quite a bit. But then when they replace the sensor based off the scan tool code and it didn’t fix the issue they become clueless on what to do and spend hours and hours trying to figure it out. Of course not all techs are like that and I have worked with some amazing technicians but man there’s a lot of part changers in the automotive world.

[@michaelbel2749]

Just rewatched this video again. When I paid attention to why the excessive air gap became a problem as the car warmed up I remembered that as steel warms up it loses magnetism. Blacksmiths will use magnets on steel to gage the temps of the metal. Hotter steel is less magnetic than cold steel.

ScannerDanner - You’re using those tools, so the review is your trusting the tools enough to use them yourself. You already mention the names of the tools and put links in the reviews. No more is needed. Have your son help you to put the giveaways together. Have him coordinate the communications / emails. The give away itself only needs a couple min video where you call out the winners. Food for thought.

Hey Paul, I found you a few months ago, and since then I've watched every one of the videos on this channel. It's content like no other. Clear, understandable, and stuffed with priceless information. My question to you, is as you prepare techs to have the knowledge and experience to get the job done quickly and competently, what about your business model? No, not the KZbin or Rosedale stuff, but your fee for service diagnostics business. For an aspiring diagnostic technician such as my self, who should be the clientele focus? Used car lots, or the DIY home mechanic who just wants to know what part to swap? What kind of price points should you set? How do you market? I think there's another whole world of video content that could be produced for the benefit of your more self-starter viewers.

Exelent diagnosis I’m not sure if anyone else commented on this , one thing you didn’t mention since the engine was replaced it could be damage to the flywheel . Although that would be a more constant miss. I remember reading an article about a Jeep that had a constant miss and the Jeep had been to several garages and it had had a engine replaced and after many stick mechanics throwing many parts at it to see what would stick, finally they found a small damage to the flywheel that they could see with the pico . Anyway I love watching the automotive detective csi videos.

[@dtnel]

In regards to the "Parts Changer" deal I did pull a Scannerdanner and change a part based on the Code with some of the data from the scan tool with minimal testing. This was based off a Chevy Pickup you did based off of the data because you didn't want to get on the ground with the gravel which I wouldn't want to either. It was a P0135 for the B1 O2 UPSTREAM Sensor heater. I checked the fuse, yes there's fuses as some people don't think there is. Fuses were good. What really led me to the sensor direction was the other 3 sensors had Appx. .54 amp except the bank 1 sensor 1. I also checked the ohms on the sensor which the wiring color for Shopkey Pro was off whether front or back probing. Tested the ohms but had to try a few different wiring probe combinations and when I did get the ohm reading it started low and went high but it went above the allowed specs per the test. Tested the new Denso O2 sensor by poking thru the plastic it came wrapped in as I don't open products if I can probe and test them thru the bag for resistance readings and the like because as we all know parts houses aren't keen on people returning electrical parts that have been opened. Now onto the knock sensors that I've been putting off to long.

Like the great Dave Decourcey would’ve said about checking inputs “Gahbage in Gahbage out” 😂. R.I.P. Dave. Loved that guys seminars. He was an entertaining character.

Eight thumbs down - that's stricly Bravo Sierra. Great video, and I, as do others, find your approach to be very educational and honest. When you pronounced the air gap to be too tight @ minute 24, I was not surprised to hear you reverse yourself @ minute 59, because, as you mentioned, no metal to metal "interaction" would result in the signal not being pulled down. Keep up the great work.

[@ScannerDanner]

Can't please everyone right? Thanks my friend

[@DavidMorales-cb4pe]

Chad Jessup i was pleased

[@ΣτέφανοςΚαντιμοίρης]

This is great stuff Paul !!! I am a member of scannerdanner premium for a week now and enjoing everyy second of it ...I also purchased your book..i am in chapter 1 and the great thing about it is that i understand 100 % of what you are trying to teach us..it all makes sence, I have a little bit of automotive background but man you really opened my mind up..Thanks

[@ScannerDanner]

this is awesome! Thank you so much

[@kasapis6]

Thanks for all the fantastic work you put into this industry

[@codysautodiagnosticsprogra8706]

Great work Paul. Love how you don’t even need a wiring diagram to get cam and crank 😂 your the man and love the videos!!

[@ScannerDanner]

Shows my age and my prime doesn't it? Lol thanks my friend.

[@codysautodiagnosticsprogra8706]

ScannerDanner just shows your amount of knowledge you have retained over the years. It’s amazing to be honest.

[@ScannerDanner]

I still love this field man and I love to figure stuff out, even on unfamiliar systems. It really is a process that is learned and continuously applied. I'm definitely behind the curve because of video now, but I'm okay with that. Everyone can just learn with me right?

[@codysautodiagnosticsprogra8706]

ScannerDanner your still educating daily that I don’t think you completely understand! New techs or seasoned ones, can pay tribute to what you have pioneered for our industry.

[@manuelamaya826]

Thanks the brothers Danner, I like works the Jeep, Chrysler, Dodge, the air gap is very important in engine 2.5 L, 3.3 L, 3.8 L, 4.0 L but the C.K.P sensors are ajustable. The original sensor have the cardboard to calibrate the air gap. Thanks for the class.

[@maureenpye9252]

Awesome experience u an d your Family are a magnificent team agree if you get board go elsewhere I am older tech and retraining this is invaluable cheers

[@nancylewis7142]

I love you SD guy, for your help, your time, I barely subscribed to your Premium Channel.

[@spelunkerd]

What a brilliant case study, complete with a car that was willing enough to tease us on camera, ha ha ha ha.

[@megasonify4800]

Paul, yep this definitely adds clarification, thanks. I'm going in as soon as she cools. Hopefully have an answer late today, definitely tomorrow.

[@ScannerDanner]

This was about the adjustment you asked me about right? How'd you like that camera shot of the adjustment? 🙂

[@megasonify4800]

Nothing short of Herculean given I'll go in there with a blind eye feeling my way to nirvana! Getting ready to take the dive; should have it b4 sunrise.

[@megasonify4800]

Well, didn't move far enough out. Started and ran perfectly for 15 minutes, then let it idle for 10 min. when it started to miss again. Heat causing expansion causing miss. Needs to cool off then I'm back in, moving out 1/8".

[@megasonify4800]

Reattached felt spacer using post-it note cutout to old sensor; installed, bingo, back in service. I think new sensor is faulty. I thought old sensor was bad when it was really my distributor. Returning part, $50 win, win, win. Thanks for both vids and replies. I hope you have students following well in your footsteps. Happy camper here.

[@ScannerDanner]

@@megasonify4800 awesome, thanks for the update. Also I can see the new sensor failing especially because it was hitting the flywheel previously

[@victorlewis8970]

Thanks a lot, for all this information, for your time to us SD.

[@arthurbright1625]

Thank you so much for providing this free your timing effort is well appreciated

[@amirmuhamad9640]

That's the way I like scanner Danner chanel your the best for me and You've gave me more idea about automotive troubleshooting. Thank you so much sir!

[@ScannerDanner]

Glad to help1 Thank yoiu

[@DEADNEO2224]

man thats exactly what my 92 cadillac deville is doing and that is the only thing i havent even looked at! Im gonna check it out and hopefully get that thing running again, i almost sold it because i couldnt figure it out!!!! fingers crossed but it sounds like that is going to be the problem after seeing that car doing the exact same thing!!!!

[@DEADNEO2224]

lol maybe if a 92 deville had a crankshaft position sensor!!

[@randyhernandez9498]

Hi! I am a mechanic in the Philippines from Moalboal Cebu , I always look on your you tube chanel and I learn a lot of knowledge about electrical problems. I personally thank you about what you are doing, helping people by showing your knowledge about how to solve problem on electrical issues. Maybe I can ask a small help from you if you have an old scanner or electrical tool that you can give me. It will be a very big help for me and .y family.

[@ScannerDanner]

I can set you up with a tool grant to shop with my friends at AESwave Email me at [e-mail] and copy and paste your message

[@jondwyer3037]

Spot on scanner danner, 10 out of ten.

[@nelsonnarciso1791]

Very well explained. Grest diagnosis. Love learning with the Danner way

[@salehhamid]

Nice video. I think the loose screw had something to do with it. Your wrigt the high signal is when the gap in the wheel passes the sensor and the low signal is when the wheel metal passes the sensor which connects the circut.

[@kenmelrose3429]

Excellent Diagnosis Paul keep up the great work

[@lordvectivus1]

Sir thank you for a great video, I watched the whole thing and I could not tear my eyes away. It was great, I am also an instructor at a school in the eastern part of Pa. I am not even in your class sir and I would really like to learn more from you and become a better instructor. I am a master teach going take the L1 test in a couple of weeks. I want to do good for my students, sir anything that you could tell me to prepare and be better I am willing to listen and learn. Sorry to bother you and thanks for your time. PS. It was great that you had your son running the camera 👍🏾👍🏾👍🏾👍🏾👍🏾👍🏾

[@ScannerDanner]

Thank you Victor! I'll help you in any way that I can. You may want to check out my premium channel when you get time. Have the school pay for it it is only $11 a month and has all of my recorded classroom lectures in it. www.scannerdanner.com

[@arthurbright1625]

Enjoy your teaching message and appreciate it you do not talk enough thank you again

[@ScannerDanner]

I appreciate that

[@rodx5571]

Just to simulate the true Danner Clan shop experience, i paused the video for 30 minutes and twiddled my thumbs waiting for the car to act up.

[@frankgonzalez24]

I had a 01 Sebring 2.5L. It would randomly die, like if the key was shut off. Some times, it would fire right back up other times I would have to wait several minutes for it to restart. It had no codes. And it ran fine. So I got it to die at home and checked for injector pulse. No pulse. Did some checks and found the crank sensor, like the one in your video, was bad and replaced it. Since then, the car ran great. On those sensors, they have a small piece of felt on the end that is used for when the sensor is installed. That piece is for setting the air gap. And from I've heard, the crank sensors on those engines tend to give problems which cause the problem I had.

[@murdock2769]

Call napper and have them read the instructions that come in the box with the sensor. When everything else fails, read the instructions. Eric 0 says there's your problem ladies.

[@naushadali95]

The best channel on you tube.thaks for all your videos

[@vincescalise4821]

you are a great teacher I like the way you explain everything ,Thanks you PAUL, PS. you do not talk to much

[@ScannerDanner]

Thanks Vince!

[@imadjawad4408]

outstanding videos every time I watch, A+

[@mharry860]

Paul, because of you Eric O and Ivan I was able to solve an evap code that pointed to the fuel inlet. Stupid Ford doesn't have a gas cap, so I cleared the code and duck taped it and it came back 15 minutes later. So it can't pull a vacuum on the fuel tank? Purge valve, problem solved for a $30 part and 15 minutes.

[@billyyoder8171]

Thank you Danners cubed. Good job. Have a blessed and safe week.

[@mikeeustice4452]

Great video I had Hyundai that was setting crank sensor codes had a great pattern till I noticed that the high and low were reversed. Took it out waved it passed a bolt and noticed that is was almost like the internal transistor would stick and the operation of the sensor was reversed then it would go back to normal
