Throttle Position Sensor: Testing and Inspection
INSPECTIONUsing 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.
