Crankshaft Position (CKP) Sensor Pick-Up Coil Short & Resistance Checks

  1. Set DVOM on 2000-ohm scale position. Connect DVOM leads to CKP sensor connector located on side of engine block. Turn ignition off. Disconnect ignition control module connectors. Check resistance between CKP sensor terminals at ignition control module connector.
  2. CKP sensor resistance should be within specification range. See CRANKSHAFT POSITION (CKP) SENSOR RESISTANCE table. If resistance is not as specified, replace CKP sensor. If sensor is within specification, go to next step.
  3. With CKP sensor installed in block, connect one ohmmeter lead to either sensor terminal at ignition control module. Touch other lead of ohmmeter to engine block. No continuity should exist. If continuity exists, CKP sensor is shorted to ground and must be repaired or replaced.
