With SST-Engine Signal Monitor

Throttle Position Sensor Inspection
Using SST-(Monitor, Engine Signal)
1. Remove the engine control module (ECM).




2. Connect the special service tools (SST)s to the ECM.




3. Verify that the throttle valve is at the closed throttle position.
4. Turn the ignition switch to ON.
5. Measure the ECM terminal 3B voltage by using a voltmeter.

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

6. If not as specified adjust the throttle position sensor.
