Crankshaft Position (CKP) Sensor: Protege
WARNING: This page is about a different car, the 1995 Mazda Protege. However, it is still accessible from the selected car via links, so may be relevant.
Unplug CKP sensor connector. Measure resistance between Blue wire and Green wire on sensor. Resistance should be 500-600 ohms at 68 °F (20 °C). Replace sensor if not within specification. When installing sensor, adjust air gap to .020-.060" (.5-1.5 mm).
