    Newbie with timing issue

    What is so bizarre about this code is that it did not show up after I replaced the timing chain last weekend. It took a few days then it showed up. Same thing yesterday after I dropped the oil pan and cleaned it out. Did a ~15 mile road test and nothing. Park it for a bit and start it up and...

    Newbie with timing issue

    I mispoke about which side I moved the slack to. I moved it to the main tension side following the instructions in the video Cloyes had on their website: https://cloyes.com/gm-2-0-2-2-2-4l-timing-replacement-cloyes-9-4201s-9-4202s/ Do you think the non-OEM VVT solenoids could be the root cause...

    Newbie with timing issue

    Did drop the pan and found all of the pieces to the top guide (both metal and plastics). Disconnected the battery while I was doing that whole process. Got everything back together filled up the oil, and all the codes were gone. Took it on about a 14 mile drive, no issues at all. Has my daughter...

    Newbie with timing issue

    Got the timing chain replaced last weekend with the Cloyes kit and everything was going good until my daughter told me that the CEL is on. Put the code reader on it and now it is showing a P0017. The car runs perfectly fine and there are no other issues. I have read that sometime using non-GM...

    P2138 After replacing Throttle Body and Throttle Pedal

    I replaced the timing chain last weekend and everything was going fine, but now it is throwing a P0017 code which leads me to believe that I should replace the cam position sensors. The engine is running fine and other than the P0017, nothing else is wrong. The one thing that I am tackling...

    Newbie with timing issue

    I am getting ready to do the timing chain on my daughters 2012 'Nox with a LEA engine. The question I am finding myself having now is are the phasers the same for both the intake and exhaust cams? The Cloyes kit (9-4201SAVVT1) that I am looking at comes with 2 of the same phaser part number and...

    P2138 After replacing Throttle Body and Throttle Pedal

    Here is another question that I have been led to after researching timing kits until my head spins. The Cloyes kit with the replacement phasers includes two of the same phasers. In doing a VIN decode, I find that my engine is the LEA engine, even though there are no flex fuel marking on it, nor...

    P2138 After replacing Throttle Body and Throttle Pedal

    Decide to take the valve cover off today as I also suspect the timing chain, and sure enough, I can see a broken upper guide. I guess I will be doing this as well and then chasing down the P2138.

    P2138 After replacing Throttle Body and Throttle Pedal

    I used OEM parts. I disconnected the battery while performing the work. The only relearn procedure I found online (without using a scanner) is to do the idle for 3 minutes, shut off for 5 minutes, then do another 3 minute idle. Is there something else that you can point me to? I am considering...

    P2138 After replacing Throttle Body and Throttle Pedal

    The other thing that I forgot to mention, is that the code only gets thrown when going WOT. This was happening before I replaced both the pedal and throttle body, and it continues to happen afterwards. Would that point to a faulty ECM?

    P2138 After replacing Throttle Body and Throttle Pedal

    Well, since I already replaced the Accelerator Pedal, then next step would be to look at the ECM I guess. Can you share that info on how to check the ECM?

    P2138 After replacing Throttle Body and Throttle Pedal

    I replaced the throttle body and the accelerator pedal and the code is still popping up. Would the next best step be to have a dealer update the ECM?

    P2138 After replacing Throttle Body and Throttle Pedal

    My daughter recently got an original owner 2012 Nox with 192K miles on it. It started doing the reduced engine power / service Stabilitrak accompanied by a P2138 code. I replaced both the gas pedal and throttle body thinking that doing both sides of the signal would fix the issue. Took it on a...
