Throttle Position Sensor: Adjustments

CAUTION:
- The TP sensor is adjusted at the factory before shipment. Unnecessary adjustment will negatively affect the engine performance.
- Adjusting the TP sensor using the throttle adjusting screw (TAS) will negatively affect the engine performance.

Closed Throttle Position (CTP) Switch
1. Verify that the throttle valve is at the CTP.
2. Disconnect the TP sensor connector.
3. Loosen the attaching screws.

Specification:

4. Insert a feeler gauge between the throttle adjusting screw (TAS) and the throttle lever. By adjusting the throttle adjusting screw (TAS), verify the continuity between the CTP switch terminals C and D are as follows using an ohmmeter.
5. Tighten the attaching screws.
- If not adjusted, replace the TP sensor.

Tightening torque: 1.6 - 2.3 N.m {16 - 24 kg.cm, 14 - 20 in.lb}

Throttle Position (TP) Sensor




1. Connect the SSTs to the DLC-2.
2. Verify that the throttle valve is at the CTP.
- If not adjusted, replace the TP sensor.
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. NGS measures and shows the voltage.

Specification:
- Closed throttle position: 0.1 - 1.1 V
- Wide open throttle: 2.6 - 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 N.m {16 - 24 kg.cm, 14 - 20 in.lb}
