Mazda CX-5 Service & Repair Manual: Oil Control Valve (OCV) Inspection
Coil Resistance Inspection
1. Disconnect the negative battery cable..
2. Remove the plug hole plate..
3. Disconnect the OCV connector.
4. Measure the resistance between terminals A and B using an ohmmeter.
-
OCV coil resistance
-
6.9—7.5 ohms [20°C {68°F}]
-
If not as specified, replace the OCV..
5. Install in the reverse order of removal.
Spool Valve Operation Inspection
1. Disconnect the negative battery cable..
2. Remove the OCV..
3. Verify that the spool valve in the OCV is in the maximum valve timing advance position as indicated in the figure.
-
If not as specified, replace the OCV..
4. Verify that the battery is fully charged..
-
If not as specified, recharge the battery..
NOTE:
-
When applying battery positive voltage between the OCV terminals, the connection can be either of the following:
-
Positive battery cable to terminal A, negative battery cable to terminal B
-
Positive battery cable to terminal B, negative battery cable to terminal A
5. Apply battery positive voltage between the OCV terminals and verify that the spool valve operates and moves to the maximum valve timing retard position.
-
If not as specified, replace the OCV..
6. Stop applying battery positive voltage and verify that the spool valve returns to the maximum valve timing advance position.
-
If not as specified, replace the OCV..
7. Install the OCV..
