Throttle Position Sensor: Testing and Inspection
THROTTLE POSITION (TP) SENSOR INSPECTION[LF, L3]
CAUTION: This inspection procedure cannot be completed correctly if the accelerator pedal position sensor has a malfunction. Before
performing this procedure, verify that any one of the DTCs (P2122, P2123, P2127, P2128, P2138) related to the accelerator pedal position
sensor is not detected.
NOTE: Before performing the following inspection, make sure to follow the troubleshooting flowchart.
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. (See TABLE[LF, L3].) See: Testing and
Inspection/Diagnostic Trouble Code Descriptions
2. Connect the M-MDS to the DLC-2.
3. Turn the ignition switch to ON position.
4. Select TP1 or TP2 PID (percentage) on the M-MDS.
5. Verify that the TP1 or TP2 PID is within the specification when the accelerator pedal not depressed. (See PCM INSPECTION[LF, L3].) See:
Testing and Inspection/Scan Tool Testing and Procedures/PCM Inspection
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.
Circuit Open/Short Inspection
1. Disconnect the PCM connector.
2. Disconnect the throttle body connector.
