DTC 84

Accelerator Pedal Position (APP) Circuit Fault:

DTC 84 Accelerator Pedal Position (APP) Circuit Fault:

CIRCUIT DESCRIPTION
The Accelerator Pedal Position (APP) module provides a voltage signal that changes relative to accelerator position. There are three sensors located within the APP module that are scaled differently.

DIAGNOSTIC TROUBLE CODE (DTC) 84 WILL SET WHEN
Powertrain Control Module (PCM) has recognized an intermittent APP fault and there are no other current APP faults stored.

ACTION TAKEN (PCM will default to)
When DTC 84 is set, a current and history DTC will set, but will not light the "Service Throttle Soon" lamp, and the vehicle will operate at limited power.

DTC 84 WILL CLEAR WHEN
The fault condition(s) no longer exist, and the ignition switch is cycled "OFF" then "ON."

DTC CHART TEST DESCRIPTION
Number(s) below refer to circled number(s) on the diagnostic chart.

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

DIAGNOSTIC AIDS
Check for faulty connections at APP module, Powertrain Control Module (PCM) and I/P connector.
