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.

2. PERFORM ACTIVE TEST USING GTS (OIL PRESSURE SENSOR)

   
   

   1. Operate the GTS according to the display and select Active Test Click here.

      Combination Meter

      Tester Display	Test Part	Control Range	Diagnostic Note
      Oil Pressure Meter Operation	Oil pressure receiver gauge	LOW, 1/4, 1/2, 3/4 or HIGH	Perform the test with the vehicle stopped and engine idling.

      OK
      Needle indication is normal.

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.

      Result

      Result	Proceed to
      Oil pressure receiver gauge operates correctly according to engine condition	A
      Oil pressure receiver gauge does not operate correctly according to engine condition (for 1GR-FE)	B
      Oil pressure receiver gauge does not operate correctly according to engine condition (for 1UR-FE)	C
      Oil pressure receiver gauge does not operate correctly according to engine condition (for 3UR-FE)	D
      Oil pressure receiver gauge does not operate correctly according to engine condition (for 1VD-FTV)	E

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

   
   

   • *1: for 1UR-FE, 3UR-FE

   • *2: for 1GR-FE, 1VD-FTV

   
   

   1. Disconnect the E120 combination meter assembly connector.

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

   3. 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
