Throttle Position Sensor: Testing and Inspection

Inspection




1. Connect the SSTs to the PCM.




2. Verify that the throttle valve is closed throttle position.
3. Turn the ignition switch to ON.
4. Measure the PCM terminal 3F voltage.

Specification:
Closed throttle position: 0.1-1.1 V
Wide open throttle: 2.8-4.5 V
(Verify that the voltage increase is directly proportioned to the throttle valve opening angle.)

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