Code 2122
Accelerator position sensor is basically just a new gas petal, at least for a chevy Silverado,
bought at O 'Reillys Auto Parts store (not online). for around $100, simply two bolts and plug and play switch built in. Got me out of (LIMP Mode)-Reduce of engine power-
You’re right that on many Silverados the accelerator pedal assembly includes the position sensors, so replacing the pedal can fix a P2122 and get the truck out of reduced power mode. It’s a fairly common repair and usually is plug-and-play like you described.
The only thing I’d add for others reading this is that P2122 isn’t always the pedal itself. The code means the ECM is seeing low voltage on that circuit, and that can also be caused by wiring damage, a poor connector, or low reference voltage from the computer. If someone replaces the pedal and the code comes back, the next step is checking the harness and the 5-volt reference circuit.
But in a lot of real-world cases, especially when the truck suddenly drops into limp mode with no other electrical issues, the pedal assembly is the culprit and your fix is exactly what solves it.
Glad it got you back on the road.
