2012 GMC Acadia SLT1 V6 3.6L with engine code B2128. What a problem do I have?

Question

My OBD 2 showed me a code P2127 that is not in the book that I got with my OBD 2 when I bought it. I have a 2012 GMC ACADIA SLT1. What problem do I have?

Answer 1

It looks like you have a concern with the engine code P2127.  The P2127 means that you have an issue with the Accelerator Pedal Position Sensor. Most likely you have to replace the Accelerator Pedal Position Sensor to fix the problem. There is more information on the P2127 code page.

Answer 2

the problem is that newer codes use there own codes after a certain number or B2128 and P2128 are different.

this car does not use B2128, try to use a different OBD-II reader the one you are using might not be compatible with your car

if the car is under warranty it is covered.
