Spool Valve Inspection

1. Disconnect the 1 P connector from the spool valve.
2. Measure resistance between the terminal and body ground.

Resistance: approx 14-30 ohms
3. If the resistance is within specifications, remove the spool valve assembly from the cylinder head, and check the spool valve filter for clogging.
•   If there is cologging, replace the engine oil filter
and the engine oil.

4. If filters are normal, push the spool valve with your finger and check its movement.
•   If spool valve is normal, check the engine oil pressure.
