Jeep compass: flashing throttle light no go – Auto Repair Chat

Surplus electronic parts : https://epartsconnect.com

Come along as I have a look at this 2014 Jeep Compass that was towed in with a flashing throttle light, engine light and a customer complaint that it won't move! I found several codes P2101, P2110, P2112, and a P2118. Hmmm could this really be a no parts required fix?

    The evap system us a very sensitive system. Keeping the system clean in the positive crankcase ventilation is preventive maintenance.
    Nice cleaner.

    i just don't like these ETM's. i had one on a Volvo that used 2 sliding potentiometers to convey throttle position. 2 forcredundancy i guess.
    During normal cruise the throttle uses the same range of opening all the time.
    Those potentiometer tracks had worn away in some places to the point that there was no proper throttle control any longer. the engine would start to vibrate and jerk as the throttle blade would vary position. very annoying. And kinda dangerous IMO
    i discovered a Chinesium kit to modify that ETM to where those pot meters were eliminated and replaced by magnetic control. Fixid it!
    Why the heck did Magneti-Marelli not make it that way from the get-go is beyond me.

    A customer at the auto store stated he had the same issues. Sometimes it would throw the same codes.
    Thanks for your Channel he knows what to say when he takes it in for any repairs.

    What a rolling pile of junk.

    Funky Throttle Body sounds like that's a case for Bootsy Collins man

  7. Avataaar/Circle Created with python_avatars sagi fern says:

    isn't there a recommendation not to move electronic throttle blades by hand… like it might ruin the electrical circuit position tuning or something like that ?

    These new vehicles are getting idiotically over complicated with whiz bang electronics.
    I've never owned a vehicle that did not have a throttle controlled by a cable, with stiff dual return springs and my next one is going to have a points type ignition, even if I have to pay a premium to own an old one.
    I am a serious believer in the KISS rule…

  11. Avataaar/Circle Created with python_avatars Alan Mathies says:

    I'm guessing too that the heat from the engine might play a role in expansion where the throttle sticks less after things warm up. Nice job going right to the problem and trying not to fire off the parts cannon.

  12. Avataaar/Circle Created with python_avatars Kevin G says:

    After cleaning did the throttle plate stop sticking ? … …Whats the relearn procedure ?

  13. Avataaar/Circle Created with python_avatars Kelsy Cunningham says:

    The throttle body needs replacing. The nylon gears inside the housing have worn and the throttle plate dithers. The issue isn't electronic, it's mechanical.

  17. Avataaar/Circle Created with python_avatars Daddy says:

    Your "forced idle" code was the PCM cutting spark on random cylinders to "force" the idle speed down as it was too high in neutral. When you put it in drive idle speed dropped to within limits. The 0% throttle test is usually at key on/engine off before start up. I had a throttle cable bind up on an "old school" gm 3800 V6 many years ago. Not fun turning a corner in heavy traffic and had to key off to avoid a crash…… unless you are on a motorcycle, the throttle cable only opens the throttle, it does NOT close the throttle! ( motorcycle has 2 cables, 1 to open and 1 to close)

    Guess the Compass was pointing south to South Main Auto.

    Also, adding some more thoughts to the Bluetooth throttle, I think that it would probably lose communication 99% of the time. I walk ten feet away from my stereo on BT with my phone in my pocket and get a bad signal, not to mention that my 10 year old laptop rarely ever connects to the same Azultooth. What's even funnier is that I walked 3 miles away from a Chinesium portable speaker and the signal never quit even once.

    To be honest though, I think there was some truth to Toyota's throttle cables going WOT from corrosion. My Toyota is 22 years old currently and had the throttle cable recalled, since then the assembly has gotten a touch of corrosion from the salty winters and I can see where a poor quality assembly could fail. I don't believe every model was affected the same way, maybe your suggestion of user error i.e. the floor mats was part of the blame.

    Never push open by hand an electronic throttle body to clean it. I learned that the hard way. Destroyed it and got a replacement which fixed the throttle light on a Jeep Commander Hemi 5.7.

  20. Avataaar/Circle Created with python_avatars Keven says:

    Car diagnostics would be so much easier instead of codes the car just makes an Eric O poopy face.

  21. Avataaar/Circle Created with python_avatars Brent Dabels says:

    To be commended. I feel most shops would have replaced the throttle body, more money in the back pocket. Usually scheduled tune-ups would include a throttle body clean or induction cleaning. Great video! Shows that not all repairs need a parts store. I hope the new generation of techs are watching and learning

  22. Avataaar/Circle Created with python_avatars Jason Campbell says:

    Eric Sir. Even if it does eventually come back . Good bless you for not running a parts cannon scam shop !!!

  23. Avataaar/Circle Created with python_avatars The Car Crazy Guy says:

    Chrysler is garbage? Wait, what? 😂

  24. Avataaar/Circle Created with python_avatars VashthStampeede says:

    I liked the accelerometer/decellerometer turn and bank indicator hanging from the mirror. Push one out was classic.

  25. Avataaar/Circle Created with python_avatars dwayne0t says:

    The cleaner you remember might have been 1,1,1 trichloroethane

    That stuff smelled great as it dissolved your lungs (⁠θ⁠‿⁠θ⁠)

  26. Avataaar/Circle Created with python_avatars VashthStampeede says:

    Great video Eric. Loved the cable comments and loved the cleaning rag comment even more.

  27. Avataaar/Circle Created with python_avatars penny pincher says:

    Sounds like commifornia laws got to N.Y. . If it works can't use it.

  28. Avataaar/Circle Created with python_avatars randy bash says:

    I had 2016 compass my throttle did the same thing @236k miles. Then like 2wks later my gas pedal it became a big mess ugh

    berkable 2 plus 2 love that stuff . honda oe chemical throttle cleaner great stuff

  31. Avataaar/Circle Created with python_avatars David McClain says:

    Even though it was trying to "push one out", it looks like you cleaned out the restriction so that it doesn't have to push so hard! Great video as usual.

  32. Avataaar/Circle Created with python_avatars Fzghbkhv Gfhhgv says:

    Did u need to do a throttle body relearn ?

  33. Avataaar/Circle Created with python_avatars Thomas Brock says:

    I feel like you should at least clean it and give it a shot before replacing it. The throttle body that is, I suppose I shoulda said that part first otherwise you could be like," clean what"?…. And good job Mr. O that is exactly what you are doing right now!!!

  34. Avataaar/Circle Created with python_avatars Vancity23 says:

    Aewsome customer must ne very happy !

  35. Avataaar/Circle Created with python_avatars Jeff Jankiewicz says:

    Always a learning experience here, I epically fail with the newer computer cars. I miss the days of my youth, no computers, just a points distributor, carburetor etc, no computer crap. Those I can fix. Obd1 I have luck with. OBD2 not so much. Threw a bunch of cash at a P0172 rich code and I think the TCM shorted and blew the eatx 20 amp fuse in a 2002 Neon SE. Now my daily is dead. F me.😬 My diag skills suck, and the parts cannon emptied my wallet.

    👍

  39. Avataaar/Circle Created with python_avatars Kevin Berg says:

    I’m still early in the video, but the feeling of misfiring when sitting in idle in park after you had the throttle limp mode is because the ECM is limiting the engine speed down to 1500rpm by shutting off injectors. When the throttle hits limp mode, it will shut the power to the throttle motor off and the throttle will sit at about 10-15% open. When you were pushing the throttle and it revved up to like 2500rpm from 1500rpm, the only thing that was changing on the engine was re-enabling all the fuel injectors (and maybe changing ignition timing). The throttle body didn’t move at all, because the power to it was shut off. It would feel like it smoothed out when you shifted into gear because the additional load of the transmission being in gear was enough for it to be able to re-enable the injector(s) it was turning off and still stay within the rpm range that it was happy with.

    I'm glad they're still a few honest mechanic's out there

  43. Avataaar/Circle Created with python_avatars Gary Archer says:

    Dr. O another great video as usual. Wish you would have demonstrated more in depth on how you were manipulating the throttle body motors by just attaching jumpers to the battery.

  44. Avataaar/Circle Created with python_avatars Robin Sattahip says:

    We've learned a couple of things, don't buy a Chrysler product should rate near the top. Cars were better when a rod and a cotter pin controlled the throttle. Oh yeah. and don't live in New York (smile).

  45. Avataaar/Circle Created with python_avatars Alison Rahn says:

    imagine if airplanes only relied on electronics and didn't have the manual cables if something failed

    Hard to drive around like a tough Harley guy when Alexa is telling you where to turn. just perfect.

    There is something to the old school physical wire connected to throttle setup.

    Got my Black Hoodie SMA, love it. I have this issue with my Escalade EXT, they say it needs to be rewired to the computer. I think I'm going to try that GUNK first. $600.00 dollar repair.

  52. Avataaar/Circle Created with python_avatars danh nguyễn says:

    That'll be the day when all of the new tech you can throw at one of these things can out smart some genuine crud. This customer must be one of your loyal followers and didn't go the parts cannon route first. You got lucky there and the been there done that experience helps too! Good vid. Besides the humor one reason I watch is I'm fairly decent with older carbureted engines and a fair amount of their issues. But what they're putting out these days and the service data that they publish for it (1) you need a computer science and scan tool degree and (2) don't forget the subscriptions you pay extra for.

    Can you believe they added Peugeot to this Fiat, Chrysler and Jeep mess?
