DTC 84 - Accelerator Pedal Position (App) Circuit Fault: Notes

The Accelerator Pedal Position (APP) module provides a voltage signal that changes relative to accelerator position. There are 3 sensors located within the APP module that are scaled differently. DTC 84 will set when the PCM has recognized an intermittent APP fault and there are no other current APP faults set. PCM will default to when DTC 84 is set, a current and history DTC will set but will not turn on the SERVICE THROTTLE SOON light, and the vehicle will operate with limited power.

1. This step determines if DTC 84 is the result of a hard failure or an intermittent condition.
