Crankshaft Position Sensor

Unplug Crankshaft Position (CKP) sensor connector. Measure resistance between CKP sensor terminals "A" and "B". See Fig 1 . Resistance should be 520-580 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).
