DTC 11: Camshaft Position (CMP) Sensor
- 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.
- 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.
- Check Component
Inspect CMP sensor. See SYSTEM/COMPONENT TESTS
article. Replace CMP sensor if necessary and perform FINAL CHECK
