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]). 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)

Open circuit
- If there is no continuity in the following wiring harnesses, there is an open circuit. Repair or replace the wiring harness.
- APP sensor terminal A and PCM terminal 1 AE
- APP sensor terminal B and PCM terminal 1
- APP sensor terminal C and PCM terminal 1AA
- APP sensor terminal D and PCM terminal body ground
- APP sensor terminal E and PCM terminal 1AL
- APP sensor terminal F and main relay terminal C

Short circuit
- If there is continuity in the following wiring harnesses, there is a short circuit. Repair or replace the wiring harness.
- APP sensor terminal A and body ground
- APP sensor terminal A and power supply
- APP sensor terminal B and body ground
- APP sensor terminal B and power supply
- APP sensor terminal C and power supply
- APP sensor terminal D and power supply
- APP sensor terminal E and body ground
- APP sensor terminal E and power supply
- APP sensor terminal F and power supply
- APP sensor terminal F and body ground
