  1. Disconnect CMP sensor harness connector. Measure resistance between CMP sensor connector terminals (component side). Resistance should be 835-1400 ohms (cold sensor) and 1060-1645 ohms (hot sensor). If resistance is as specified, go to next step. If resistance is not as specified, replace CMP sensor.
  2. Check for open or short in wiring between ECM and CMP sensor. See WIRING DIAGRAMS article. If problem exists, repair wiring as necessary. If problem does not exist, go to next step.
  3. Remove and inspect CMP sensor. Also inspect signal plate. If problem exists, replace CMP sensor and/or signal plate as necessary. If problem does not exist, replace ECM.
