WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 1994 Mazda MX-5 Miata, 1992 Mazda MX-5 Miata, 1992 Mazda MPV, 1992 Mazda B2200, and 1991 Mazda MX-5 Miata. However, it is still accessible from the selected car via links, so may be relevant.
Disconnect solenoid valve connector. See Fig 1 . Check resistance of each terminal to ground. Resistance should be 13-27 ohms. If resistance is not 13-27 ohms, check wiring for opens or shorts. If no opens or shorts are found, replace solenoid valve(s).
