"Reduced Engine Power" Code (Accelerator Position Sensor)
When driving my 2005 Chevy Silverado, 2500 HD, 6L the "reduced engine power" comes up on the dash. I had the local mechanic connect his scan tool to the truck, he said to replace the accelerator position sensor. So after replacing 2 of them with no correction to the problem. I took it to the Chevy dealer, they recommended replacing the wiring harness to the sensor. Two weeks after replacing the wiring harness the reduced engine code came up again.
I have a CarMD scan tool. Error Code P1125 comes up when plugged in.
The definition of the code stated : Accelerator Position Sensor 1 and 2 Circuit Malfunction
