Resistance Inspection (Off-Vehicle)

WARNING: This page is about a different car, the 2004 Mazda MPV. 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 specified, replace the solenoid valve.
- If it is normal, replace the harness.
