to be honest it has been up and down all day!!! just come back up. while i am doing some info research, here is what causes the code to set
The accelerator pedal position (APP) sensor 1 and the APP sensor 2 are potentiometer type sensors, each with the following circuits:
The control module provides the APP sensors with a 5-volt reference circuit and a low reference circuit. The APP sensors then provide the control module signal voltages proportional to pedal movement. The APP sensor 1 signal voltage is low at rest and increases as the pedal is depressed. The APP sensor 2 signal voltage is low at rest and increases as the pedal is depressed. When the control module detects that the APP sensor 1 and the APP sensor 2 signal circuits are out of correlation with each other, DTC P1125 sets.
this system is really hard to track down the problem without a scan tool that can read real time data. in most cases this problems turns out to be a bad wire terminal on one of the circuits. this is what you are going to have to do first. I have included a wiring diagram, you will need to check these wires for resistances. none of the circuits should have more than 5 ohms. if all the circuits check ok, you may a problem with the throttle control module
The PCM detects that the difference between APP sensor 1 and APP sensor 2 is more than the predicted value.
You are very welcome. and please let me know if you need any further help with this!!!
Thanks for using JA!!
great!! keep me posted and let me know how things are going?
Have a great evening!!
