METER / GAUGE SYSTEM Oil Pressure Gauge Malfunction

DESCRIPTION

The oil pressure sender detects the oil pressure generated when the engine is started. The combination meter determines that the engine is running when the engine speed is 400 rpm or more, and determines that the engine is cranking when the engine speed is 200 rpm or less. The oil pressure receiver gauge detects and indicates the oil pressure applied to the oil pressure sender.

  3. INSPECT OIL PRESSURE GAUGE ASSEMBLY (OIL PRESSURE SENSOR)


    1. Temporarily replace the oil pressure sender gage assembly with a new or normally functioning one.


    2. Perform an operation check and check that the operation of the combination meter returns to normal.

      OK
      Needle is as shown in illustration when engine is stopped.
      Operation of combination meter returns to normal.

  4. CHECK HARNESS AND CONNECTOR (COMBINATION METER - OIL PRESSURE SENSOR AND BODY GROUND)


    • *1: for 3UR-FE

    • *2: for 1VD-FTV


    1. Disconnect the E121 meter connector.

    2. Disconnect the D6*1, C72*2 gauge connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      E121-6 (S) - D6-1 (S) Always Below 1 Ω
      E121-6 (S) - C72-1 (S)
      E121-6 (S) or D6-1 (S) - Body ground Always 10 kΩ or higher
      E121-6 (S) or C72-1 (S) - Body ground

    OK
