PROCEDURE


  1. INSPECT ENGINE OIL PRESSURE SWITCH ASSEMBLY

    CAUTION:


    • A004AW3

      When working near the engine room while the engine has started or the power source mode is ignition switch to ON (IG), do not touch the fan and generator V belt or rotating components such as the fan, etc.

    • Touching the fan and generator V belt or rotating components such as the fan, etc. could result in your hand or clothing getting caught and pulled in.


    • A0049EQC11
      *a High temperature areas

      Do not touch the engine or exhaust manifold converter sub-assembly when they are hot.

    • Touching the engine or exhaust manifold converter sub-assembly when they are hot could result in burns.


    1. Disconnect the engine oil pressure switch assembly connector.

    2. Start the engine.

    3. Check the resistance.


      1. A00475A

        Measure the resistance according to the value(s) in the table below.

        Standard Resistance
        Tester Connection Condition Specified Condition
        1 - Switch body Idling 10 kΩ or higher
        Engine stopped Below 1 Ω

        If the result is not as specified, replace the engine oil pressure switch assembly.

    4. Connect the engine oil pressure switch assembly connector.
