Crankshaft Sensor Pick-Up Coil Short & Resistance Checks
- Set DVOM on the 2000-ohm scale. Connect leads to crank angle sensor, located on side of engine block. On 2.5L models, it will be necessary to remove ignition module. Crankshaft sensor resistance should be within specification in CRANKSHAFT SENSOR RESISTANCE table. If resistance is not as specified, replace sensor.
- Connect one ohmmeter lead to either sensor terminal. Touch other lead of ohmmeter to engine block. No continuity should exist. If continuity exists, sensor is shorted to ground and must be replaced.
