- Adjusting the TP sensor using the throttle adjusting screw (TAS) will negatively affect the engine performance.

Throttle Position (TP) Sensor




1. Connect the SSTs to the DLC-2.
2. Verity 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:
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.

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