ENGINE OIL CONTROL VALVE CHECK
 
 
Required Special Tool:
  • MB991658: Test Harness
 
 
 
 
 
<Checking the Operation Sound>
1. Disconnect the engine oil control valve connector.
2.
cautionTo prevent the coil from burning, keep the duration of the voltage application as short as possible.
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 special tool MB991658 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 the resistance between terminals.
Standard value: 6.9 - 7.9 Ω [at 20°C (68°F)]
3. If the resistance is not within the standard value, replace the engine oil control valve.
