I change the App on a 2008 Acura tl and the check engine light came back with the same codes p2138 p2122 what else can cause the codes to come back on


code p 2138 refers to throttle position (TP) sensor/switch D/E-- voltage correlation=== causes --- wiring -- tp sensor /switch

code p 2122 refers to accelerator pedal (APP) sensor /switch D --low input===causes --wiring short to ground --APP sensor/ switch

also refers to engine control module (ECM) , idle control ---high input===causes ---wiring short to positive --TP sensor--ETS control valve (ETS----electronic throttle system)

P2138,p2128


Problem is with the tps (throttle positioning sensor) or wiring. Does it idle weird? or stall?

Trouble Code: P0643 Every time I step on the gas peddle, there are two warning lights that come on: the ASR skid light and the ESP . Then I have no power. I can only get up to 35 MPH.


The vehicle enters limp mode.

P0643 is a generic code. Sensor reference voltage high. This would indicate a possible wiring issue somewhere. This could be on the electronic throttle module somewhere as it is triggered by using the throttle. Unfortunately it doesn't sound like a simple cheap fix. Look for a mercedes independant commercial garage in your area to have a look at it.

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...


-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.

P2138 code for a 2004 dodge ram 5.7 liter


Were the APP codes there BEFORE they replaced the BCM? APP codes usually are an indicator the throttle body needs to be replaced. As a precaution, some recommend to replace the throttle body AND the sensor on the gas pedal together. Unfortunately, this is a dealer only repair most o the time, since the ECM will have to be flashed to sync the new sensors.

Reduced engine power, service traction control, service stabilitrak


First of all a scan tool is need for this not a code reader, you need to view scan data after you find what code is stored in the PCM. It could have a problem with the powertrain control module, wiring, or the Accelerator Pedal Position (APP) Sensors. Here are a few codes that could set .
DTC P2120: Accelerator Pedal Position (APP) Sensor 1 Circuit

DTC P2122: Accelerator Pedal Position (APP) Sensor 1 Circuit Low Voltage

DTC P2123: Accelerator Pedal Position (APP) Sensor 1 Circuit High Voltage

DTC P2125: Accelerator Pedal Position (APP) Sensor 2 Circuit

DTC P2127: Accelerator Pedal Position (APP) Sensor 2 Circuit Low Voltage

DTC P2128: Accelerator Pedal Position (APP) Sensor 2 Circuit High Voltage

DTC P2138: Accelerator Pedal Position (APP) Sensor 1-2 Correlation

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
