Accelerator Pedal Position Sensor
Description
The Accelerator Pedal Position (APP) sensor is located inside the accelerator pedal. The accelerator pedal position
sensor can not be serviced separately from the accelerator pedal. The accelerator pedal and the APP sensor must
be replaced as a unit.
Operation
The Accelerator Pedal Position (APP) sensor in the accelerator pedal determines the opening angle of the throttle
valve in the throttle body. The APP sensor is a hall sensor, and the pedal value information is sent to the Engine
Control Module (ECM). The accelerator pedal position sensor is supplied with 5 volts from the ECM. As the accel-
erator is pressed, this produces a change in the voltage. The ECM determines the position of the throttle valve and
actuates the throttle valve motor based on inputs from the APP sensor.
Removal & Installation
1. Disconnect the negative battery cable.
2. Remove the instrument panel lower trim panel.
3. Disconnect the APP sensor electrical connector (2).
4. Remove the three APP sensor mounting bolts (1).
(Tighten: APP sensor mounting bolts to 11 N·m)
5. Remove the APP sensor with the pedal.
6. Installation is in the reverse order of removal.
Electronic Throttle Control Actuator
Description
The throttle body is located on the intake manifold. It controls air into the intake manifold. The electronic throttle
control actuator consists of the throttle control motor and the throttle position sensor. The throttle control motor is
operated by the Engine Control Module (ECM) and it opens and closes the throttle valve. The throttle position sensor
detects the throttle valve position.
