APPS (Accelerator Pedal Position Sensor)

DESCRIPTION
The Accelerator Pedal Position Sensor (APPS) is located inside the vehicle. It is attached to the accelerator pedal assembly.

OPERATION
The Accelerator Pedal Position Sensor (APPS) provides the Engine Control Module (ECM) with two DC voltage signals which change as the position of the accelerator pedal changes. One of the DC voltage signals will be half the voltage of the other signal.

REMOVAL
CAUTION: Do not attempt to separate or remove the Accelerator Pedal Position Sensor (APPS) from the accelerator pedal assembly. The APPS is replaced as an assembly along with the pedal. If sensor is removed from pedal, its electronic calibration may be destroyed.

1. Disconnect 6-way electrical connector at top of APPS (2).
2. Remove APPS lower mounting bolt (4) and two mounting nuts.
3. Remove pedal and APPS assembly from vehicle.

INSTALLATION
CAUTION: Do not attempt to separate or remove the Accelerator Pedal Position Sensor (APPS) from the accelerator pedal assembly. The APPS is replaced as an assembly along with the pedal. If sensor is removed from pedal, its electronic calibration may be destroyed.

1. Position pedal and APPS assembly to its mounting bracket.
2. Connect 6-way electrical connector to top of APPS (2).
3. Install APPS lower mounting bolt (4) and two mounting nuts.
