Throttle Position (TP) Sensor Inspection
THROTTLE POSITION (TP) SENSOR INSPECTIONNOTE: Perform the following inspection only when directed.
1. Verify that no DTC related to APP sensor has been detected.
- If any DTCs related to APP sensor have been detected, perform the DTC inspection.
2. Connect the WDS or equivalent to the DLC-2.
3. Turn the ignition switch to ON position.
4. Select TP1 or TP2 PID (percentage) on the WDS or equivalent.
5. Verify that the TP1 or TP2 PID is within the specification when the accelerator pedal not depressed. PID/DATA Monitor Table (Reference)
6. Operate the accelerator pedal and verify that the TP1 or TP2 PID (percentage) changes as shown in the following graph.
- If not verified, perform the "Circuit Open/Short Inspection".
- If there is no open or short circuit, replace the throttle body. (See INTAKE AIR SYSTEM REMOVAL/ INSTALLATION.)
Circuit Open/Short Inspection
1. Disconnect the PCM connector.
2. Inspect the following harnesses for open or short circuit. (Continuity check)
