Millenia V6-2255cc 2.3L DOHC (1995)
Throttle Position Sensor: Testing and Inspection
With SST-Engine Signal Monitor
Inspection
(Integral) Closed Throttle Position Switch
1. Verify that the throttle valve is closed throttle position.
2. Disconnect the throttle position sensor connector.
3. Check for continuity between throttle position sensor connector terminals C and D by using an ohmmeter
4. If no continuity, adjust the throttle position sensor.
5. Insert a 0.37 mm (0.015 in) feeler gauge between the throttle adjusting screw (TAS) and the throttle even Verify that there is no continuity
between terminal C and D.
6. If there is continuity, adjust the throttle position sensor.
Throttle Position Sensor
Using SST-(Engine Signal Monitor)
1. Remove the ECM.
2. Connect the SSTs to the ECM.
3. Verify that the throttle valve is closed throttle position.
4. Turn the ignition switch to ON.
5. Measure the ECM terminal 3B voltage by using a voltmeter.
Specification
