Throttle Position Sensor: Testing and Inspection
InspectionUsing ohmmeter
1. Disconnect the throttle position sensor connector.
2. Measure the resistance between throttle position sensor connector terminals A and C by using an ohmmeter.
Specification: 4.0-6.0 k Ohms
3. If not as specified, replace the throttle position sensor.
4. Connect the throttle position sensor connector.
5. Adjust the throttle position sensor after installation.
Using SST (Engine Signal Monitor)
1. Remove the PCM.
2. Connect the SSTs to the PCM.
3. Verify that the throttle valve is at the closed throttle position.
4. Turn the ignition switch to ON.
5. Measure the voltage at the PCM terminal 3F.
