1. Resistance inspection.
Using an ohmmeter, measure the resistance between the terminals.
Resistance: 6.9 - 7.9 ohm at 20 °C (68 °F)
2. Movement inspection.
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 does not adhere.
HINT: Bad returning of the valve by entrance of foreign objects causes subtle pressure leak to the advanced direction. Then, DTC can be
detected.
