Throttle Position Sensor: Testing and Inspection

INSPECTION
Using Ohmmeter
- Disconnect the throttle position sensor connector.




- Measure the resistance between throttle position sensor connector terminals A and C by using an ohmmeter.

Specification: 4.0 - 6.0 kohms

- If not as specified, replace the throttle position sensor.
- Connect the throttle position sensor connector.
- Adjust the throttle position sensor after installation.

Using the Engine Signal Monitor
- Remove the PCM.




- Connect the Special Service Tools (SST)s (Engine Signal Monitor) to the PCM.
- Verify that the throttle valve is at the closed throttle position.
- Turn the ignition switch to ON.
- Measure the voltage at the PCM terminal 3F.




- If not as specified, adjust the throttle position sensor.

Using The NGS
- Connect the SSTs New Generation Star (NGS) tester to the data link connector-2.
- Verify that the throttle valve is at the closed throttle position.




- Select the PID/DATA MONITOR AND RECORD function.
- Select "TP V" on the NGS display. The NGS measures and shows the voltage.




- If not as specified, adjust the throttle position sensor.
