WARNING: This page is about a different car, the 1994 Mazda Protege, 1994 Mazda MX-3, and 1994 Mazda 323. However, it is still accessible from the selected car via links, so may be relevant.

Disconnect ISC valve electrical connector. Connect ohmmeter to Idle Speed Control (ISC) valve 2-wire connector. Measure resistance. Resistance should be 11-13 ohms at 68°F (20°C). If resistance is not within specification, replace ISC valve.
