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.

OK


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

  1. Check that the needle moves in accordance with the engine speed.

    OK:
    Needle is as shown in illustration when engine is stopped.
    Needle moves when engine is running.

4.CHECK HARNESS AND CONNECTOR (COMBINATION METER - OIL PRESSURE SENSOR)
  1. *1: for 1UR-FE, 3UR-FE
  2. *2: for 1GR-FE, 1VD-FTV

  1. Disconnect the E120 combination meter assembly connector.

  1. Disconnect the D18*1, C47*2 oil pressure sender gauge assembly connector.

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

    Standard Resistance:
    Tester Connection
    		Condition
    		Specified Condition
    E120-6 (S) - D18-1 (S)
    		Always
    		Below 1 Ω
    E120-6 (S) - C47-1 (S)
    		Always
    		Below 1 Ω
    E120-6 (S) or D18-1 (S) - Body ground
    		Always
    		10 kΩ or higher
    E120-6 (S) or C47-1 (S) - Body ground
    		Always
    		10 kΩ or higher
