Accelerator Sensor
Description
The accelerator sensor is located on the right front body crossbeam.
Operation
The accelerator sensor monitors road conditions, and is designed to detect engine misfires. It sends a signal to the
Engine Control Module (ECM), and the ECM determines if a possible misfire condition exists.
Removal & Installation
1. Disconnect the negative battery cable.
2. Disconnect the accelerator sensor electrical con-
nector.
3. Remove the accelerator sensor (1).
4. Installation is in the reverse order of removal.
Manifold Absolute Pressure Sensor
Description
The Manifold Absolute Pressure (MAP) sensor, is mounted to the front of the engine.
Operation
The MAP sensor monitors the pressure in the intake manifold. The pressure in the manifold moves a diaphragm
connected to resistors which alter their resistance values. The MAP sensor sends an output voltage signal to the
ECM to determine the pressure in the intake manifold.
Removal & Installation
1. Disconnect the negative battery cable.
2. Disconnect the MAP sensor electrical connector.
3. Remove the MAP sensor mounting bolt (1).
(Tighten: MAP sensor mounting bolt to 6 N·m)
4. Remove the MAP sensor.
5. Installation is in the reverse order of removal.
