Oil Pressure Gauge Malfunction

METER: 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 CAN COMMUNICATION SYSTEM

(a) Check for DTCs 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) Operate the Techstream according to the display and select or "Active Test" Meter / Gauge System.

OK:

Needle indication is normal.

Combination Meter:





Result





C -- REPLACE COMBINATION METER ASSEMBLY Removal

B -- INSPECT OIL PRESSURE SENDER GAUGE
A -- Continue to next step.

3. INSPECT OIL PRESSURE SWITCH

(a) Disconnect the D1 switch connector.





(b) Apply battery positive (+) voltage to the pressure switch 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.

NG -- REPLACE OIL PRESSURE SWITCH Removal
OK -- Continue to next step.

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





(a) Disconnect the J28 meter connector.

(b) Disconnect the D1 switch 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

5. INSPECT OIL PRESSURE SENDER GAUGE

(a) Disconnect the E11 sender 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.

6. CHECK HARNESS AND CONNECTOR





(a) Disconnect the J28 meter connector.

(b) Disconnect the E11 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
