Circuit Description
The Accelerator Pedal Position (APP) sensors are mounted on accelerator pedal/TAC module assembly. The are 3 individual APP sensors within one housing and 3 separate signal, ground and reference circuits are used which are contained with the Throttle Actuator Control (TAC) module. The APP sensor signal voltage increases as accelerator pedal is depressed. The signal circuits pull to ground within the TAC module.
DTC will set when APP sensor No. 1 disagrees with APP sensor No. 2 by greater than 10.5 percent and APP sensor No. 1 disagrees with APP sensor No. 3 by greater than 10.5 percent and conditions met for less than one second.
