Inspection [12/2019 - ]: Procedure

WARNING: This page is about a different variant/trim than selected.
  1. INSPECT OIL PRESSURE AND TEMPERATURE SENSOR 
    1. Check the oil pressure and temperature sensor output voltage.
      1. Apply 5 V between terminals 3 (VC) and 2 (GND).

        *a Component without harness connected
        (Oil Pressure and Temperature Sensor)
        *b Voltage Applied between Terminals
        NOTE:
        • Be careful when connecting the leads as the oil pressure and temperature sensor may be damaged if the leads are connected to the wrong terminals.
        • Do not apply more than 6 V to terminals 3 (VC) or 2 (GND).

        HINT: 

        If a stable power supply is not available, connect 4 nickel-metal hydride batteries (1.2 V each) or equivalent in series.

      2. Measure the voltage between terminals.

        Standard Voltage

        Tester Connection Condition Specified Condition
        4 (TOUT) - 2 (GND) 20°C (68°F) Approximately 1.5 to 2.5 V*

        *: The output voltage changes depending on the voltage applied to the terminals.

        If the result is not as specified, replace the oil pressure and temperature sensor.
