NO. 10 OIL PRESSURE GAUGE INDICATION IS DEFECTIVE (OIL PRESSURE GAUGE NEEDLE DOES NOT MOVE FROM THE L POSITION OR LESS)


id0903d5858100

10

Oil pressure gauge indication is defective (oil pressure gauge needle does not move from the L position or less)

POSSIBLE CAUSE

• PCM malfunction
• Instrument cluster malfunction
• Oil pressure switch malfunction
• Connector or pin malfunction
• Short circuit in wiring harness between CAN-L, CAN-H and GND
• Open circuit in CAN wiring harness (CAN-L, CAN-H)
• CAN wiring harness (CAN-L, CAN-H) short each other

Diagnostic procedure

STEP

INSPECTION

ACTION

1
• Start the engine.
• Does the oil pressure gauge needle indicate L position or more?
Yes
Troubleshooting completed.
No
Go to the next step.
2
• Do the speedometer, the tachometer, and the water temperature gauge operate normally?
Yes
Go to the next step.
No
Go to Step 5.
3
• Does the engine oil need replenishment?
Yes
Add the engine oil.
No
Go to the next step.
4
• Start the instrument cluster input/output check mode.
• Inspect the oil pressure gauge using the check code 28.
• Is the oil pressure gauge normal?
Yes
Inspect the PCM, oil pressure switch, or connectors.
No
Replace the instrument cluster.
5
• Start the engine.
• Does the ABS warning light turn off?
Yes
Inspect the PCM or connectors.
No
Go to the next step.
6
• Disconnect the negative battery cable.
• Measure the resistance between the DLC-2 terminals F and E.
• Is the resistance 54-66 ohms?
Yes
Go to the next step.
No
Go to Step 8.
7
• Disconnect the negative battery cable.
• Inspect the DLC-2 terminals F and E for short to power supply or GND.
• Is there any malfunction?
Yes
Inspect the wiring harness and CAN system-related module.
Repair or replace the malfunctioning part.
No
Replace the instrument cluster.
8
• Turn the ignition switch off.
• Inspect the instrument cluster connector terminals for poor connection (such as damaged/pulled-out pins, and corrosion).
• Are the terminals normal?
Yes
Go to the next step.

No
Repair or replace the terminal.
9
• Disconnect the negative battery cable.
• Measure the resistance between the instrument cluster connector terminals 1J and 1L.
• Is the resistance 114-126 ohms?
Yes
Inspect the wiring harness and CAN system-related module.
Repair or replace the malfunctioning part.
No
Replace the instrument cluster.
