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..
