I for one am glad this fixed your issue ! I wondered what happened, but hopefully this has cured the problem...

Hey Paul, just wanted to stop by and say thank you for all the incredible content and educational videos. I've been a dealer technician for a little over 4 years now, but i started watching you when i was in tech school. You have been invaluable to me as a diagnostic tech and really helped me elevate my skill set. Wish good health to you and your family.

[@ScannerDanner]

Thank you so much! This means the world to me to hear this type of feedback

[@SmittySmithsonite]

Great to see you and some of the family, Paul! I finally got a minute to see what you’ve been up to. I got so disgusted with electronics that I got rid of my ‘07 Silverado and bought a 1993 Ram W250 with a Cummins & a 5-speed.😂 The Silverado had an intermittent communication issue, similar to what you had going on here with that turbo sensor. Been going on for over 15 years. I am just done with all of it. I like simplicity. I learned a TON from you, but I just couldn’t get over my own mental hurdles with the electronic stuff. I still appreciate you sharing your knowledge with all of us! Kept me going for a few years longer than I would have otherwise. Onward we go! 😊 You and the family have yourselves a Happy New Year.🍻

[@isalmankhan1]

Wish if you could scope test it, but in this case what you did was right👍🏻👍🏻👍🏻 The old sensor looked quite clean I've seen worst, but it's surprising how it was failing intermittently🧐 Thanks for sharing SD, Love you Guy's & please bring James Danner in next video, it's been a while😍😍😍 Lot's of Prayers for your Mom & your Family, Stay Blessed🙏🏻🙏🏻🙏🏻

I definitely know the feeling of faults taking a long time to really manifest themselves. I remember having a 93 GMC Sierra once that had a battery drain that took me 2 years to find out what was going on with it. Checked it 3-4 times and the drain was never there. Then finally after 2 years, it did it while I had the meter hooked up to it, and was able to trace it down then.

[@thomasmartin2950]

WHAT WAS THE DRAIN???

[@dmorley100]

@@thomasmartin2950 passenger side door lock switch had some crud on connector side that would let just a little bit of current cross over to ground. Finally grew enough crud to give a consistent drain reading.

Nice video Paul

[@andrewseyfarth]

Hey Paul, love your videos, I have a real doozy of a problem on a customer’s car that I can’t figure out, I could really use your diagnostic insight, thanks Andy

[@andrewseyfarth]

So I’ve got a doozy, 2018 colorado 3.6, we did a used engine swap and it has turned into a disaster. 23k on engine and used the original wiring harness from the original engine, the fuel rails, injectors and injector harness and high pressure sensor are all from the salvage engine. After the first test drive we got a p163a with no CEL, we have had these codes also but not consistently, p0090, p00c8 and p228c, those codes only occurred once at different times the p228c occurred by itself with no other codes and put me in reduced power, the p0090, p00c8 and p163a all occurred together and gave me reduced power at one point also but it seems the only codes that returns with consistency is the p163a but does not trigger a reduced power situation, the vin is-1GCGSCEN5J1118135, we’ve changed the high pressure fuel pump with a GM unit, called identifix and went through the diagnostics and replace the ECM, no good, then identifix suggested I run a new circuit straight from the ecm to the high pressure fuel pump, I used new pins on the x3 ecm connector and new 2 pin connector at the hpfp regulator and after about 60 miles the code come back, occasionally I’ll get a p228c with reduced power and the p163a, I’ve watched fuel pressure while driving and low is always between 50 and 60 and high is always over 550psi, freeze frame showed rail pressure at 61 psi when the light flagged, but there was no drivability change. The p163a always returns and the p228c occasionally flags and puts me in reduced power. I’m truly at a loss now it is very strange. We replaced the engine and trans because the head was leaking coolant and it had 190k on it and we found a salvage combination with 23k, thought it was a better solution, boy was I wrong…

[@andrewseyfarth]

Also this p163a code as per definition and strategy is very vague and the diagram simply shows 2 wires from high pressure regulator to the ecm, strategy doesn’t explain how the ecm is recognizing the fault all it says it that it’s a circuitry control code

[@ScannerDanner]

What would be helpful is to define all of these codes. That way people don't have to go look them up before being able to offer help.

[@andrewseyfarth]

Sorry about that, the codes that keep returning are P163A Code - Control Module Fuel Pressure Regulator 1 Control System Circuitry Performance P228C Code - Fuel Pressure Regulator Control Performance Low Pressure The p163a returns consistently after two trips and the p228c has returned 3 times on different trips over about 150 miles and put me in reduced power mode These 2 codes did also occur one time as well but have not come back since: P00C8 Code - Fuel Pressure Regulator High Control Circuit P0090 Code - Fuel Pressure Regulator Control Circuit

[@Mikes_Repair]

How is the high pressure pump doing as far as actual vs desired pressures? Does it seem to be regulating normally?

[@mike-yp1uk]

Great video.

If I was at a rest area and saw Paul with his scanner out, I'd have to do a double take. Feel I owe you a good bottle of Bourbon for the content you've dropped for free over the years. This has saved me time and money as a technician and hobbyist. Corinthians 10:24. No one should seek their own good, but the good of others.

[@ScannerDanner]

Thank you brother

[@tomtke7351]

spending 5 hours (@$130/hour labor) on a 'science project' is definitive in locating what's wrong. Spending $100 on very probable parts, instead, wins the pragmatic award.

[@majicdude88]

Unless those probable parts don’t work or solve the problem, which is highly likely lol

[@tomtke7351]

@@majicdude88 if the parts qualify as "probable" it means they are 99% likely. Typically the parts cannon is wasteful but it is a tradeoff between excessive labor and minor part expense.

[@freeride202]

I believe that statistic is around 70%. So you would be wrong roughly 30% of the time. That is if you are relying on professional experience. Internet sourced fixes drop that number down greatly. Someone that specializes in one brand or type of vehicle will see pattern failures but that should only be used to point you in the direction to start testing. Otherwise you run into the risk of being wrong 30% of the time. I see this every day as a shop owner.

[@tomtke7351]

@@freeride202 I'm not suggesting the 'part-store's-scanner" approach of code => part R&R. I'm only suggesting there's times when part R&R is appropriate as a troubleshooting step. My suggestion is (and only with a seasoned tech's good judgement) a $50 part R&R might be better than $500 of troubleshooting. When Thomas Edison was chided: "have you invented a lightbulb yet," would reply, "No! but I know a 100 ways that Don't Work!" I.E., a failed part R&R narrows the field. P.S. thx for being a business owner! You're invaluable to society. You provide a service and you employ workers... a double win.

[@ScannerDanner]

The key with all of this is proper communication with the customer. If the new sensor does not fix it, the customer must be made aware of the next path moving forward and that is one where the shop is NOT working for free! Also the part that was suggested is also NOT being refunded. The layperson doesn't understand what we deal with and it is our job to inform them properly BEFORE any work is done. Lay out the expectations. If they don't like what you are saying they can take the problem elsewhere.

[@AV-sm5ir]

My mother has a Toyota RAV4 ala30 2.2 diesel ad-ftv. Few years back she would get limp mode on the highway going on a vacation and coming back(10-12 hour total one way straight trip), but only after driving 3-5 hours straight (and with a heavy foot) and multiple times on said trip. Not being with her I could only read some stored codes afterwards. The one that came back and was of importance had something to do with DPF (can't remember the exact code). She had this the year after too. She also said that if she tanked for gas and had a long enough break it sometimes went away and took some time to come back. but I was not able to recreate this problem at home and for a year and until the next big trip everything was perfect. So I was like hmm this seems/might be like something getting really really hot/heat soaked and electronic. I knew the differential sensor for the DPF was mounted pretty close to the turbo (4-5 inches), just in case I ordered a new one and also moved it about 5-6 inches away wich worked fine with the flexible hoses (no bends,or pinched lines after). So because of the rather harder to recreate conditions I semi diagnosed and semi guessed that this sensor might be the issue, the car was about 9 years old and 80-90k miles so a sensor going bad was not that strange. She has been on multiple vacations since with same driving and milage. The problem was resolved by moving the sensor. She has been on the same vacation the years before since she had it new but finally this sensor was giving up under intense and long duration of heat.

[@alv1970]

Think it could have something to do with altitude?

[@careyautorepairs]

How may times in 2 years have you had a full load in this vehicle ? Do you think that also could've been some of the issue because it's under load more and working harder or would that extra load not be relevant to this problem ?

[@ScannerDanner]

full load and long periods of time with boost definitely had a factor on this sensor failure and when it would show it's ugly face

I love that you held onto that sensor for 1/ 1/2 years so you could further verify the issue. You could have easily just installed it the first time there was a boost fault. Never would’ve been able to actually verify the issue! Practice what you preach brother!

[@ScannerDanner]

Thanks man, unfortunately I was still unable to prove the fault to everyone.

[@Troy_Built]

Sometimes you have to do what you have to do. One night in Indianapolis my brother's truck blew a brake line. In an Autozone parking lot I put two compression fittings and line on it as they were closing up.@@ScannerDanner

The only way you would ever be able to 100% diagnose a problem this intermittent would be if cars were fitted with flight data recorders like on airplanes, that measure every single sensor at all times lol.

[@D2O2]

So if this had been a customer 1.5 years ago and they just came back, what do you do and what do you charge, then and now?

[@gordondowdy833]

As a shop owner myself, it is 12 months, or 36,000 !!! Same issue ? It's a product fault, not the shop...Just my opinion...

[@ScannerDanner]

no parts were changed 1.5 years ago. Diagnostic time was spent then and you charged them then. IT's not free when they come back! To be honest though, I would have changed this sensor 1.5 years ago. The reason I did not was to be able to prove the fault with you guys. I failed on that front again due to the family being packed in the car on a 20 hr drive. No way I was going to put them through that just for video purposes.

[@D2O2]

I think this could have been a real life situation where this vehicle rolls into the shop loaded with a family wanting to get somewhere in a hurry and they just want the sensor replaced now so they can get on the road instead of spending diagnostic time to then replace the sensor anyway. Real pressure to just be a parts changer.

[@brianmason8400]

Few years ago, i had an F-150 come in and the only symptom/cust complaint was intermittent "no crank". Cust couldn't say if it was dead battery, bad this/ that or what.....come to find out the truck was bought from the auction and it seriously took 8 "come backs" over a 6 month period. Every time it would act up, the customer would wait until it started and then bring it in, OR towing it in, things would get jarred and it fired right up. Again, took 6 months of come backs to finally get it to act up while at the shop. Turns out the PCM was dropping out all communications. We priced him a PCM install w programming, he decided to resell it through the auction...😔😔😔

Side note after working on a couple of these BS limp mode every 6 months to a year. Flagging a fuel pressure sensor. Both ended up being the ecu.
