Resistance Inspection (Off-Vehicle)

WARNING: This page is about a different car, the 2005 Mazda RX-8. However, it is still accessible from the selected car via links, so may be relevant.

Remove each solenoid valve. (See SOLENOID VALVE REMOVAL/INSTALLATION .)
Measure the resistance of each solenoid valve individually.
- If not within the specification, replace the solenoid valve. (See SOLENOID VALVE REMOVAL/INSTALLATION .)
