With SST-Engine Signal Monitor

Throttle Position Sensor Inspection
Using SSTs (Monitor, Engine Signal)
1. Remove the powertrain control module (PCM).




2. Connect the special service tools (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 PCM 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.
