Then go to Step 2.

STEP 2. Check harness connector B-106 engine oil control
valve and harness connector B-10 at ECM for damage.

Q:Is the harness connector in good condition?

YES:

Go to Step 3.

valve connector

(2)

Measure the resistance between engine oil control valve side
connector terminal No. 1 and No. 2.

Standard value: 6.9 - 7.9 Ω [at 20°C (68°F)]

Q:Is the measured resistance between 6.9 and 7.9 ohms [at

20°C (68°F)]?

YES:

Go to Step 4.

NO:

(3)

Measure the voltage between terminal No. 1 and ground.

｠

Voltage should be battery positive voltage.

(4)

Turn the ignition switch to the "LOCK" (OFF) position.

Q:Is battery positive voltage (approximately 12 volts)

present?

YES:

Go to Step 5.

NO:

Repair it because of open circuit or harness damage

between relay box (fuse No. 22) and engine oil control
valve connector B-106 (terminal No. 1). Then go to Step
7.

STEP 5. Check for open circuit and short circuit to ground
and harness damage between engine oil control valve
connector B-106 and ECM connector B-10.
