WARNING: This page is about a different car, the 2002 Toyota Highlander. However, it is still accessible from the selected car via links, so may be relevant.
  1. Disconnect CMP sensor harness connector. Measure resistance between CMP sensor connector terminals (component side). Resistance should be 835-1400 ohms with sensor temperature of 14-122°F (-10-50°C) and 1060-1645 ohms with sensor temperature of 122-212°F (50-100°C). 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 does not exist, go to next step. If problem exists, repair wiring as necessary.
  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.
