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

Accelerator Pedal Position (APP) module provides a voltage signal that changes relative to accelerator position. There are 3 sensors located within APP module that are scaled differently. DTC 84 will set when PCM has recognized an intermittent APP fault and there are no other current APP faults set.

When DTC 84 is set, a current and history DTC will set but will not turn on SERVICE THROTTLE SOON light, and vehicle will operate with limited power.

NOTE: Test numbers refer to numbers on diagnostic chart.

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