ENGINE OIL CONTROL VALVE CHECK
Checking the Operation Sound
1. Disconnect the engine oil control valve connector.
CAUTION: To prevent the coil from burning, keep the duration of the voltage application as short as possible.
2. Check that the operation sound of the engine oil control valve can be heard when the positive battery voltage is supplied to the engine oil control valve. (Use the jumper wires to connect terminal No.2 of the engine oil control valve connector to the positive battery terminal and terminal No.1 to the negative battery terminal.)
3. If the operation sound cannot be heard, replace the engine oil control valve.
Checking the Coil Resistance
1. Disconnect the engine oil control valve connector.
2. Measure resistance between terminal No.1 and terminal No.2 of the connector at the engine oil control valve side.
Standard value: 6.9 - 7.9 ohms [at 20°C (68°F)]
3. If resistance is not within the standard value, replace the engine oil control valve.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
