Accelerator Pedal Position Sensor: Testing and Inspection
ACCELERATOR PEDAL POSITION (APP) SENSOR INSPECTION
NOTE: Before performing the following inspection, make sure to follow the troubleshooting flowchart. (See FOREWORD.) See: Computers and
Control Systems/Testing and Inspection/Initial Inspection and Diagnostic Overview/Foreword
Voltage Inspection
1. Turn the ignition switch to the ON position.
2. Verify that the voltage at PCM terminals 5F (M-MDS PID: APP1) and 5C (M-MDS PID: APP2) increases while gradually increasing the
accelerator pedal opening angle according to the accelerator pedal opening angle.
-
If it can be verified, go to the next step.
-
If it cannot be verified even though the related wiring harnesses have no malfunction, replace the accelerator pedal.
3. Verify that the voltage at PCM terminals 5F (M-MDS PID: APP1) and 5C (M-MDS PID: APP2) is as indicated in the table.
APP Sensor Output Voltage
-
If it cannot be verified, replace the accelerator pedal.
Circuit Open/Short Inspection
1. Disconnect the PCM connectors.
2. Disconnect the APP sensor connector.
3. Inspect the following wiring harnesses for 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 4X
-
APP sensor terminal B and PCM terminal 5AB
-
APP sensor terminal C and PCM terminal 5C
-
APP sensor terminal D and PCM terminal 4Y
-
APP sensor terminal E and PCM terminal 5AE
-
APP sensor terminal F and PCM terminal 5F
