Throttle Position Sensor: 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

    • Tighten the screws securely after adjustment.
