Description

The oil level sensor detects the level of engine oil, and then transmits the oil level signal to the combination meter.

DTC Logic

DTC DETECTION LOGIC

NOTE

:
When the following conditions are satisfied, the combination meter reads the resistance value of oil level sensor.

The combination meter does not read the oil level sensor resistance value within 5 minutes after the previous reading of oil level sensor resistance value by the combination meter.

1. Turn the ignition switch OFF.

2. Wait for 5 minutes or more, then open the front door.

DTC (B2321: OIL LEV SEN OPEN, B2322: OIL LEV SEN SHORT) is also detected at the timing described above.

Diagnosis Procedure

1.CHECK OIL LEVEL SENSOR SIGNAL CIRCUIT

1. Turn ignition switch OFF.

2. Disconnect connectors of combination meter and oil level sensor.

3. Check for continuity between combination meter harness connector and oil level sensor harness connector.

*1: HR16DE engine models *2: MR16DDT engine models *3: K9K engine models

4. Check for continuity between combination meter harness connector and ground.

Is the inspection result normal? YES >> GO TO 2.

NO >> Repair harnesses or connectors.

2.CHECK OIL LEVEL SENSOR GROUND CIRCUIT

Check for continuity between combination meter harness connector and oil level sensor harness connector.

*1: HR16DE engine models *2: MR16DDT engine models *2: K9K engine models

Is the inspection result normal? YES >> INSPECTION END

NO >> Repair harnesses or connectors.

Component Inspection

1.CHECK OIL LEVEL SENSOR

1. Turn ignition switch OFF.

2. Disconnect oil level sensor connector.

3. Check resistance between oil level sensor terminals 1 and 2.

Is the inspection result normal? YES >> INSPECTION END

NO >> Replace oil level sensor.
