INSPECTION

a. Resistance inspection.
1. Using an ohmmeter, measure the resistance between the terminals.
Resistance: 6.9 to 7.9 Ohms at 20 °C (68 °F)
b. Movement inspection.
1. Connect the positive (+) lead from the battery to terminal 1 and negative (-) lead to terminal 2, and check the movement of the valve.
NOTE: Confirm the valve moves freely and does not stick in any position.
HINT: Bad returning of the valve by catching foreign objects causes subtle pressure leak. The subtle pressure leak will cause the cam to
advance, and this condition will set a DTC.
