Gm code p2120


Code p2120 is accelerator pedal position sensor APP sensor 1 circuit apparently this is known as the reduced engine power syndrome and is quite common on the avalanche. There is no mechanical linkage from gas pedal to throttle body and it is quite common for the throttle position sensor located on throttle body to mess up and throw this code and also for one of the wires to the throttle position sensor to get hot become brittle and sometimes break. I would start there

Check engine code


I'm new to this website, have a problem with my '93 Dakota, 5.2L but thought I'd post to your question.

The readers would need more information than what you supplied.

On my Dakota, to check the CEL(Check Engine Light), cycle the ignition switch to RUN-OFF-RUN-OFF-RUN, then count the flashes of the CEL. There will be a distinct pause between each set of 2 number flashes, finally ending with a code of 55 signaling the end of the code display.

Some of the codes will keep the CEL lit all the time, while others will store but not light the CEL when running.
If you post the codes you see, and look them up, it might give you (and the reaers here) a better idea of your problem.
