I have a 04 dodge Durango hemi 5.7. Error code p0648- p2122- p2127- p2138. Car is idling at 10mpg. The dealer replaced the throttle body and recommended I pay them $900 bucks to replace the PCM, I replaced...


Chrysler has a service bulletin on these codes along with a software update. Contact the dealer that did the throttle body replace and ask if they did the software update. If not, have them do it. If that fixes the problem, have a little nose-to-nose discussion with the service manager about getting a partial refund on their initial diagnosis

-Need to determine what these codes are before replacing parts.
-After replace, The CODE NEED to be Erase.
-Find these code in its repair manual. So you can pin point what is the problem.

I have a 2010 Chevy impala. Reduced engine power and check engine light also comes on but won't stay on. Codes are P2138 P2122 P0455


Hi Rosalee_IM,
The codes your vehicle is storing are for low voltage from your accelerator pedal position sensor and a gross evaporative emission leak. The code P2122 and P2138 are directing you to test the accelerator pedal position circuit and/ or sensor. This is the cause of the reduced power concern you are feeling.The P0455 is telling you there is a large leak in the evaporative emission system. The most common cause for this code is a loose or incorrectly installed gas cap.I hope this helps clarify the concerns you are experiencing. If you'd like more information on how to trouble shoot the problems,drop me a line. Please include the model Impala you have,(LS,LT or LTZ) and the engine size. I will do my best to get back to you as soon as possible.Thanks, Chuck

Same 3 codes , p0455, p0442, & p2138 on my 2009 Chevy Impala and brought the car to a General Motor or Buick Dealer Service Department to replace vent solenoid or solenoid fuel tank evaporator control . Also replaced gas pedal position sensor.
