Jeep Wrangler - Crank Shaft Position Sensor - locate and test

Jeep crankshaft position sensor - Where is it and how do you test it? I show symptoms and a simple test to diagnose this hidden in a hole sensor. Plus a very important tip in reinstalling it should you need to replace it.
Here is a link (affiliate) to the crankshaft position sensor that fits my Jeep: amzn.to/2yrVO63 . Mine has the round style plug. Some of the later model YJ & XJ has the oval / flat plug. Please be sure you are ordering the correct part to save you some time and frustration.

Hi from Spain. Could you help me? I just swap the tf999 to ax15 in my old 4.0l 91 YJ and now I don't have sparks in my plugs...I think that the problem is in the CSP, but is new (part number 56027866AB , buy in amazon )... the YJ Works perfect before the swap at morning. what do you think about it? Problem in the CSP, is different the PCM Between auto 4.0 and manual YJ...or anything. THANKS FOR ADVANCE, thanks for the re-clocking template and sorry for my language blunders.

We are thankful for all your extra kindness during your video's 🎉

[@GeraldThomasphotojunkie]

Great video it will help a lot of folks! Just a point of information, a bad crankshaft position sensor will shut the engine down when it's running and will not start when you attempt to start it back up, it shuts down spark. Sometimes it will restart after the engine cools down, but will shut down once the engine warms up again. A camshaft position sensor will allow the engine to run until you shut it off, and then will not start up again, it shuts down the fuel system. So if your Jeep shuts down abruptly and won't start back up with no spark, it's most likely a crankshaft position sensor, and if you park your Jeep and the next time you go to start it and it won't start up but you have spark, and the fuel pump doesn't run when you turn the key on, it's most likely a camshaft position sensor that's inside the distributor housing.

[@Poweraddicts]

Thanks guy. I've got three Jeeps, CJ7, Cheokee, JK Wrangler. I once twisted wrenches on cars and trucks before I did the same on aircraft for 30+ years. I got way behind the power curve going from the newer cars/trucks/Jeeps from turbine engines. Way different technology. Your videos bring me up to this "new" technology for me. Oh yeah. I'm 77 and still cranking.

[@Poweraddicts]

You go brother!! I hope I'm still cranking at that age. I really enjoy tinkering with Jeeps, Cars & motorcycles. Eventually I'm gonna get another Jeep to do a v8 swap on.

I just viewed your video tonight and found it to be of great help and of course I also signed up. Thanks for all the information and the way you put it out, very easy to understand too. I just acquired a non-running 91 Laredo, 4.0L, with the AW4 from a family member who couldn't get it started after last driving it a year ago. He put in a new fuel pump and the injectors are getting fuel. He put in new plugs and told me it was getting spark. I've recently installed a new N.S.S. safety switch and it cranks over in park and neutral, but no start. I will be checking out the CPS in the morning to see if its good, but based on all my reading and viewing, I think it might be the CPS or Coil. Manny Thanks. Tio AL.

Thanks for this video. I have a 1988 Cherokee that the crankshaft position sensor wire hit the exhaust manifold & melted. I barely got it home.

I'm hoping that after I replace the sensor again I can get it to start. Thanks.

There are 2 sensors that will prevent them from starting. Crankshaft position sensor and camshaft position sensor. If I understand what you are describing as it just randomly shutting off, that is typically the crankshaft position sensor. Good luck, hope you get it fixed!! Have a great day!

[@TwoOldFarts]

I'm confused - the video shows the round plug & you are testing across B & C - then you say that the round was replaced with a flat plug - A B C - then you say "you want the 2 outside poles" - does that mean test A & C on the flat plug? also, what is the 3rd pole? is it the power supply? & what voltage should it be?

[@ericsmith8961]

Good video thanks for your time.

[@pauleinerson5745]

When he tests the CPS in ohms and says it should have no resistance, the meter shows 1, and no resistance should show 0.0 When I bought a new CPS for my 4.0, it read 0.0 ohms, same as the one I removed after viewing this video. It turned out not to be the CPS but my Coil that gave me a false reading looking good, when I tested it, before researching additional reasons for the no-spark and found this video. The video did give some really good advice to be careful not dropping the CPS bolts in to the Bellhousing.

[@Poweraddicts]

No, Actually there is no fault in the video. The reading is correct. If you were watching the meter it stays at "1" all the time with the leads "not touching" anything. When I touch the leads together it then went to almost 0, just measuring the resistance of the leads themselves. What I was saying in the video, there should be no change at all in the meter reading and there wasn't. The display in the meter never changed as it shouldn't when reading across pins B and C. I'm reading and quoting this straight from the Chrysler service manual as I type this ... "Place an ohm meter across terminals B and C. The meter reading should be open (no resistance). Replace sensor if a low resistance is indicated". The part where is says "The meter reading should be open" means an open circuit, as in, there should be NO change in the meters reading and again, there wasn't. Yes, I've measured sensors after releasing this video that also read 0.0 and the sensor still worked. But technically, the meter should read the sensor just like it is when its turned on with the leads touching nothing. This video will soon be 3 years old. That Crank sensor is the same sensor I'm still running today. No issues with the sensor or the video. Coils can be finicky testing them. Sometimes it depends on whether the coil is hot, warm or cold as to if it test good or bad. Crank position sensors can be tricky as well to diagnose. About 95% of the time when a crank sensor fails .. its done and not coming back to life. I know of a Cherokee that has had 2 Crank sensors changed out. Each time when the engine cooled it would start up and run till the engine got hot ... then .. fall on its face again. Testing the Crank sensor after the engine cooled enough to touch, it tested good be cause is was cooled down. The symptoms at this point says that the coil could be the issue. Tested the coil, it tested good because it had cooled down. Swapped in a known good coil, still fell on its face after getting hot. Swapped in another Crank sensor ran for over a year trouble free. When it acted up again showing the same symptoms, we swapped a crank sensor in a all was good again. Glad you got your ride going! Have a great day :-)

[@johnbull6909]

If the bolt falls in the hole then you can remove a steel plate on the bottom of the bell housing and fish it out from there, you don't have to separate the transmission from the engine.

[@Poweraddicts]

That is true. The throw out bearing went out in my Dad's TJ. We pushed that plate back a bit and ball bearing came rolling out.

Question everything I’ve read on the forums is saying 200 ohms of resistance is normal, but I bought a cps from Oreillys and it had about the same Resistance as the one I took out but the Jeep wouldn’t start at all with the new one but still will with the old one, so had them order me another one lol I’m at a loss tho 1990 Jeep Wrangler 2.5 TBI

Great Video, Just one question... No Spark usually means Bad Coil.. How come you didn't test the Coil For Spark first before Blaming the CPS ? Does the CPS in fact make the Coil Work?

[@Poweraddicts]

On Jeeps (Wranglers and Cherokees) of this generation, the CPS "usually" goes out before the coil. But obviously not every time. Yes, if the CPS fails, the coil stops firing. Good question .. thanks for asking! Have a great day!

[@shebboleth]

Hey Drew! - I'm new to Jeep World having recently inherited a '90 Cherokee. I'm a mechanic wanna' be and (sure enough!) when doing my first Jeep tune-up managed to twist off the hold down screw on the distributor cap. SO....if there are any great tips on how to get the distributor back in CORRECTLY the 1st time , that'd be great. The vehicle runs but idles roughly after warm up. I heard a read a MILLION reasons why but have resolved to replacing each component that could be the culprit until I get it right. Don't know what else to do! The next potential culprit is CPS. and NOW, after watching your vid, I have a clue what I am doing AND WHY!!!The WHY is a big deal with me. When I "get" why it works or doesn't I seem more confident in what I am doing. Anyway, Thanks for taking time to 'splain stuff to us old "new" Jeep guys, keep up the good work, Man, you ARE appreciated!

[@Poweraddicts]

+Bill Evans Thats without a doubt one video I need to do. Kinda hard to explain without showing it. Basically get number 1 cylinder on top of compression stroke (not exhaust stroke). Drop the distributor in so the the rotor button is pointing at number one cylinder. That will get you in the ball park. The rest is using a timing light to set the engine to factory timing spec by the harmonic balancer. Just a note, if the CPS was bad, it wouldn't rut at all. If it did it may run for a short time then shut down. I think the HOW isnt complete until the WHY is put with it. I naturally over analyze everything. I'm not satisfied with a half way explanation. That tends to show in my videos. I get flamed occasionally for my video being too long. Thats fine, haters will be haters. I get more praise for over explaining than negative. So .. I'm doing all right :-). So with that being said.. Thanks for the great review! That keeps me reassured that Im doing the right thing. Have a great day!

Liked video!

[@Poweraddicts]

Thanks! Hope the video helped!

What a coincidence, I was station on Fort Campbell

[@XxBrMagicxX]

If I'm not having my check engine light come on when I'm cranking, is that my ECM or could it be my crankshaft position sensor? Thanks so much

[@Poweraddicts]

Verify you are getting power to the ECM. If you are getting power to the ECM and have no check engine light at any time. More than likely you have a bad ECM.

[@kingsoulsurfer41]

Have an important question the valve cover gasket do you have to use loctite on those bolts

[@Poweraddicts]

Nope .. no loctite.

[@GlorybetoGOD7]

Thanks.

[@Poweraddicts]

You're welcome! Hope it helps. Have a great day!

Great video. I have a 1997 Jeep Wrangler 2.5L, Automatic. I was getting code 11 doing the key trick. I changed the crankshaft position sensor and notice that mine was installed opposite of your video and on studs with nuts. I assume this is because mine is an automatic, 2.5 L. I have looked at a lot of videos and pictures on line and don't see any that are installed like mine? Do you know anything about this?

[@Poweraddicts]

Being that yours is a 97, you have a TJ which is a newer engine generation than the YJs like mine.

[@GregBloss]

I have a 94 YJ 4cyl and it's been running really rich lots of fumes, and when you de-excelerate it pops like a pop corn popper. I have replaced the MAP, upper and lower exhaust/oxygen sensors, idle control sensor, all plugs, wires, distributor cap and rotor and little or no difference. Any thoughts? I think it's timing but I'm told you can't change the timing on these?

[@galehess6676]

Please tell me you figured the jeep out? Any luck on this? I have a 4cyl that went from 16 mpg to 8, did the coil, map, all kinds of sensors and tune up.

[@davidbarkley8450]

Is this a hall effect sensor? If so looking up info. on one could show how to check it out.

[@Poweraddicts]

Its a type of hall effect sensor. Chrysler took a standard hall effect and tweaked it to their need. Can't remember exactly what the subtle difference is. Thanks for dropping in! Have a great day!

[@ja4476]

I lost the bolt that hold the sensor sensor on my 91 jeep yj 4.0l automatic, someone here have info about that bolt ? I got to buy another one but dont have info about it... thanks...

[@ivhadway2mini]

Haven't found the video yet, but how would you test the camshaft position sensor?

[@Poweraddicts]

I haven't created that video yet. I need to get that one done so that will have all the engine sensors covered.

[@dwaynegolliher1886]

Also, have you had success with non Mopar replacement parts? Just curious as they are way expensive...

[@Poweraddicts]

I get my sensors from the junkyards when I can find them. So to be honest, I haven't tried any of the store bought non-mopar sensors so I can't give an honest answer.

[@pusherpilot]

Hey Man thank for posting this video. I am in the process of rebuilding a 1991 jeep YJ. I have a problem no one else has though. My connector from the wiring harness has been on the exhaust manifold and is burnt to no recognition. I want to direct wire it to the CPS wiring but I dont know what color wire goes to the CPS wiring. Do you have a diagram of what color wire goes to the correct pin of the wiring harness connector? I can figure out what I need if I only knew which one of the 3 wires from the wiring harness goes to the correct pin. Hope this makes sense.

[@Poweraddicts]

+Paul Roberts Yep .. it makes total sense. I'll look this weekend at the color codes. During the week I pull long hours. But, if you gently take a razor blade and cut off the burnt insulation to separate the copper parts of the wires. The copper part of the wires should at least allow you to see where they are going well enough to rewire. I've done that many many times.

[@pusherpilot]

+Power Addicts - Jeep, car and motorcycle tips Thanks for that input but my connector was badly burned and the wire connections were broken. I guess I could do trial and error method but it would be nice to know which one of the 3 wires go to the corresponding pin. I cant find a diagram of this anywhere.

[@Poweraddicts]

I've got an extra sensor in my YJ tool box. I'll try to remember to look tomorrow.

[@pusherpilot]

Thanks for your help.

[@Poweraddicts]

The wiring diagrams I've looked at are crap! LOL .. Does yours have the round (like in the video) or oval shaped plug?

[@MrSlickmonster6973]

92 yj 4.0lt. it turns off while going down the street. then it turns right back on. then off again and on again while driving. but it stays on while in neutral. any ideas??? thanks

[@Poweraddicts]

Thats kind of a headscratcher. I'd like to say CPS. But the intermittent and then staying running in Neutral leads me toward a wiring issue. Why? When the engine is running it is vibrating. When in neutral there is no or little physical load on the chassis or engine mounts so therefore, less vibration to cause the "possible wire short or break" to act up. Start the engine and leave it idling in neutral (if it is a stick shift, chock the wheels so it doesn't roll). Start at the harness at the CPS, move the harness around by hand to see if it shuts it down. Then go the Camshaft Position Sensor in the distributor and do the same thing. Typically the Crank and Cam sensor are the only two sensors that will shut the engine down completely. After moving the harness and you get no issues, replace the Crank Sensor first, then the Cam sensor. I have seen those come and go intermittently. Hope that helps, but without actually hands on checking it out myself, kinda hard to diagnose. Please drop a line back in here if you discover what the issue is. I'd really like to know for sure myself. Good luck, Thanks for checking out my video! Have a great day!
