Oil Pressure Gauge Malfunction

METER / GAUGE / DISPLAY: METER / GAUGE SYSTEM: Oil Pressure Gauge Malfunction
- 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.

INSPECTION PROCEDURE

PROCEDURE

1. CHECK DTC

(a) Use the Techstream to check if the CAN communication system is functioning normally Reading and Clearing Diagnostic Trouble Codes.

Result





B -- GO TO CAN COMMUNICATION SYSTEM Service Precautions
A -- Continue to next step.

2. PERFORM ACTIVE TEST USING TECHSTREAM (OIL PRESSURE RECEIVER GAUGE)

(a) Connect the Techstream to the DLC3.

(b) Turn the ignition switch to ON.

(c) Turn the Techstream ON.

(d) Enter the following menus: Body Electrical / Combination Meter / Active Test.

(e) According to the display on the Techstream, perform the Active Test.

Combination Meter





OK:

Needle indication is normal.

NG -- REPLACE COMBINATION METER ASSEMBLY Removal
OK -- Continue to next step.

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

(a) Disconnect the E13 gauge connector.





(b) Apply battery positive (+) voltage to the sender gauge terminal through a test LED.

(c) Check that the LED does not illuminate when the engine is stopped.

(d) Check that the LED flashes when the engine is running. The number of flashes varies with engine speed.

OK:

LED flashes when engine is running.

LED does not illuminate when engine is stopped.

Result





D -- REPLACE OIL PRESSURE SENDER GAUGE ASSEMBLY Removal

C -- REPLACE OIL PRESSURE SENDER GAUGE ASSEMBLY Removal

B -- REPLACE OIL PRESSURE SENDER GAUGE ASSEMBLY Removal
A -- Continue to next step.

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

(a) Disconnect the H37 meter connector.





(b) Disconnect the E13 gauge connector.

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

Standard Resistance:





NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR

OK -- REPLACE COMBINATION METER ASSEMBLY Removal
