With SST-Monitor, Engine Signal

Throttle Position Sensor Adjustment
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. Loosen the attaching screws.
5. Turn the ignition switch to ON.
6. Adjust the throttle position sensor so that the ECM terminal 3B voltage is as specified, 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
proportioned to the throttle valve opening angle.)

7. Tighten the attaching screws.

Tighten torque: 1.6-2.3 N-m (14-20 in-lb)

8. If not adjusted, inspect the throttle position sensor harness.
9. If harness is OK, replace the throttle position sensor.
