Accelerator Pedal Position Sensor: Testing and Inspection
ACCELERATOR PEDAL POSITION (APP) SENSOR INSPECTION[L3]
NOTE: Before performing the following inspection, make sure to follow the troubleshooting flowchart. (See FOREWORD[L3].)
1. Connect the M-MDS to the DLC-2.
2. Turn the ignition switch to ON position.
3. Select APP1 and APP2 PID on the M-MDS.
4. Verify that the APP1 and APP2 PID is within the specification when the accelerator pedal not depressed. (See PCM INSPECTION[L3]). See:
Computers and Control Systems/Testing and Inspection/Scan Tool Testing and Procedures/PCM Inspection
Circuit Open/Short Inspection
1. Disconnect the PCM connectors.
2. Disconnect the APP sensor connector.
3. Inspect the following wiring harnesses for an open or short circuit. (Continuity inspection)
