P1282

Diagnostic Chart:

Schematic:

The Accelerator Pedal Position (APP) sensor system consists of two independent sensors that read differently scaled values of one another in order to command the throttle butterfly to a particular position. The APP sensor signal circuits are monitored continuously. This DTC will set if APP 2 signal voltage should fall below a calibratable value.

DTC PARAMETERS
This DTC will set when:
^ APP 2 signal voltage less than 0.48 volts
^ Battery Voltage greater than 7 volts
^ Conditions exist for longer than 140 milliseconds

DTC P1282 is a (type A) DTC.

DIAGNOSTIC AIDS
To locate an intermittent problem, use the Scan tool to monitor APP sensor 2 with ignition On, engine Off.

Wiggling wires while monitoring APP sensor 2 may locate the area where an open or short to ground exists.
