Throttle Position Sensor: Adjustments

THROTTLE POSITION SENSOR (TPS) ADJUSTMENT




1. Connect a HI-SCAN to the data link connector.
2. If a HI-SCAN is not used, connect a digital type voltmeter between connector 1 and 3
3. Turn the ignition switch to the ON position (do not start engine) and check that the TP Sensor output voltage is as specified. If a HI-SCAN is used, press code No. 14 and read the voltage.
Standard value 300 - 900 mV





4. If the voltage is not within the specification, loosen the TPS mounting screws and adjust it by turnings the TPS.

NOTE: Turning the TP Sensor clockwise increases the output voltage.
Tighten the screws securely after adjustment.





5. Turn the ignition switch to the OFF position.
