DTC 11: Camshaft Position (CMP) Sensor

  1. Check Power Supply

    Turn ignition off and disconnect CMP sensor harness connector. Turn ignition on. Measure voltage between CMP sensor harness connector terminal "b" (Black/White wire) and ground. See Fig 1 and Fig 2 . If battery voltage is present, go to next step. If battery voltage is not present, verify harness continuity between CMP sensor and ECCS relay (Black/White wire), and between CMP sensor and ECM (Black/White wire). Repair harness or connectors as necessary.
  2. Check Input Signal Circuit

    Turn ignition off and disconnect ECM harness connector. Verify harness continuity between CMP sensor connector terminal "d" (Green/Black wire) and ECM connector terminals No. 41 and 51 (120-degree signal), and between terminal "c" (Green/Yellow wire) and ECM terminals No. 42 and 52 (one degree signal). See Figure , Figure and Fig 1 . If continuity is present, go to next step. If continuity is not present, repair harness or connectors as necessary.
  3. Check Component

    Inspect CMP sensor. See SYSTEM/COMPONENT TESTS article. Replace CMP sensor if necessary and perform FINAL CHECK  .
