Throttle Position Sensor: Adjustments
Using The Engine Signal Monitor1. Remove the PCM.
2. Connect the Special Service Tools to the PCM.
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 PCM 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.
Tightening torque: 1.6-2.3 Nm (14-20 in.lbs.)
8. If not adjusted, inspect the throttle position sensor harness.
9. If harness is OK, replace the throttle position sensor.
Using Special Service Tools (NGS)
1. Connect the Special Service Tools to the data link connector 2.
2. Verify that the throttle valve is at the closed throttle position.
3. Loosen the attaching screws.
4. Turn the ignition switch to ON.
5. Select the PID/DATA MONITOR AND RECORD function of the NGS.
6. Select "TP V" on the NGS display. NOS measures and shows the 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 pro-portioned to the throttle valve opening angle.
7. Tighten the attaching screws.
Tightening torque: 1.6-2.3 Nm (14-20 in.lbs.)
8. If not adjusted, replace the Throttle Position Sensor.
