Diagnosis & Repair

WARNING: This page is about a different car, the 2000 Toyota ECHO. 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 terminals (component side). Resistance should be 1630-2740 ohms (cold sensor) or 2065-3225 ohms (hot sensor). If resistance is not as specified, replace CMP sensor. If resistance is as specified, go to next step.
  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 camshaft timing pulley. If problem exists, replace CMP sensor and/or camshaft timing pulley as necessary. If problem does not exist, replace ECM.
