Throttle Position Sensor: Adjustments
ADJUSTMENT- Verify that the throttle valve is at the closed throttle position.
- Disconnect the throttle position sensor connector.
- Turn the ignition switch to ON.
- Measure and record the voltage at the harness side connector terminal C by using the voltmeter,
Specification: 4.5 - 5.5 V
- Connect the throttle position sensor connector.
- Remove the PCM.
- Connect the SSTs (Engine Signal Monitor) to the PCM.
- Verify that the throttle valve is at the closed throttle position.
- Turn the ignition switch to ON.
- Loosen the throttle position sensor screw.
- Adjust the throttle position sensor so that PCM terminal 3F voltage is within the specification.
- Tighten the throttle position sensor screw.
Tightening torque: 1.6 - 2.3 Nm (14 - 20 in. lbs.)
- Fully open the throttle valve and verify that the voltage at PCM terminal 3F is within the specification.
Wide Open Throttle
- If not as specified, replace the throttle position sensor.
- Adjust the throttle position sensor after installation.
Using the NGS
- Verify that the throttle valve is at the closed throttle position.
- Disconnect the throttle position sensor connector.
- Turn the ignition switch to ON.
- Measure and record the voltage at the harness side connector terminal C by using the voltmeter.
Specification: 4.5 - 5.6 V
- Connect the throttle position sensor connector.
- Connect the SSTs (NGS) to the data link connector-2.
- Select the PID/DATA MONITOR AND RECORD function.
- Select the "TP V" and verify that the throttle valve is at the closed throttle position.
- Loosen the throttle position sensor screw.
- Adjust the throttle position sensor so that throttle position signal voltage is with in the specification.
- Tighten the throttle position sensor screw.
Tightening torque: 1.6 - 2.3 Nm (14 - 20 in. lbs.)
- Fully open the throttle valve and verify that the voltage is within the specification.
- If not as specified, replace the throttle position sensor.
- Adjust the throttle position sensor after installation.
