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 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 that the continuity between the CTP switch terminals C and D are as shown using an ohmmeter.
5. Connect the TP sensor connector.
6. Tighten the attaching screws.
- If not adjusted, replace the TP sensor.

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

Throttle Position (TP) Sensor




1. Disconnect the PCM connector.
2. Connect the SST (ESM adapter harness) between the PCM and the vehicle harness connectors.
3. Verify that the throttle valve is at the CTP.
4. Loosen the attaching screws.
5. Turn the ignition switch to ON.
6. Verify that PCM terminal 3B voltage is within the specification, by adjusting the throttle position sensor.

Specification
CTP: 0.1 - 1.1 V
WOT: 2.8 - 4.5 V
(Verify that the voltage increase is directly proportioned to the throttle valve opening angle.)




7. Tighten the attaching screws.
- If not adjusted, replace the TP sensor.

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