DTC P0335: Crankshaft Position Sensor Circuit Malfunction: Testing

NOTE: Record freeze frame data. Check for service bulletins and on-line information.
  1. Disconnect 12-pin harness connector X-09, located at top right side of engine. See WIRING DIAGRAMS article. Connect voltmeter between female X-09 harness connector terminals "J" (Red wire) and "K" (Green wire). Check AC voltage output while cranking engine. If voltage is not present, go to next step. If voltage is present, go to step  8 .
  2. Turn ignition off. Check resistance between female X-09 harness connector terminals "J" (Red wire) and "K" (Green wire). If resistance is 0 ohms, go to next step. If resistance is 315-385 ohms, check pulse wheel for damage. Replace as necessary and go to step  12 . If continuity is not present, go to step  5 .
  3. Disconnect CKP sensor. Check for continuity between female X-09 harness connector terminal "J" (Red wire) and ground. Check for continuity between female X-09 harness connector terminal "K" (Green wire) and ground. If continuity is not present, go to next step. If continuity is present, repair short to ground and go to step  12 .
  4. Check for continuity between female X-09 harness connector terminals "J" (Red wire) and "K" (Green wire). See WIRING DIAGRAMS article. If continuity is not present, go to next step. If continuity is present, repair short between circuits and go to step  12 .
  5. Check CKP connector. If connector is okay, go to next step. If connector is faulty, repair as necessary and go to step  12 .
  6. Check for continuity of Red wire between female X-09 harness connector terminal "J" and CKP sensor harness connector terminal "A". Check for continuity of Green wire between female X-09 harness connector terminal "K" and CKP sensor harness connector terminal "B. If continuity is present, go to next step. If continuity is not present, repair open circuit and go to step  12 .
  7. Check resistance between CKP sensor terminals "A" and "B". If resistance is 315-385 ohms, check for poor connection or bent terminals. Repair as necessary and go to step  12 . If resistance is not 315-385 ohms, replace CKP sensor. Go to step  12 .
  8. Ensure ignition is off. Disconnect PCM harness connector. Check PCM and harness connector terminals. See Figure . If terminals and connector are okay, go to next step. If fault is present, repair as necessary and go to step  12 .
  9. Check for continuity of Pink wire between male X-09 harness connector terminal "J" and PCM harness connector terminal No. 21. See WIRING DIAGRAMS article. Check for continuity of Green wire between male X-09 harness connector terminal "K" and PCM connector terminal No. 22. See Figure . If continuity is present, go to next step. If continuity is not present, repair open circuit and go to step  12 .
  10. Check for continuity of Pink wire between male X-09 harness connector terminal "J" and ground. Check for continuity of Green wire between male X-09 harness connector terminal "K" and ground. If continuity is not present, go to next step. If continuity is present, repair short to ground and go to step  12 .
  11. Check for continuity between male X-09 harness connector terminals "J" (Pink wire) and "K" (Green wire). If continuity is not present, go to next step. If continuity is present, repair short between circuits and go to next step.
  12. Reconnect all components. Turn ignition on. Using scan tool, clear DTC. Start engine. Using scan tool, select MAF PID. Ensure MAF PID is more than .36 lb. min. (2.7 g/sec.). Recheck DTCs. If DTC P0335 is present, replace PCM and go to next step. If DTC P0335 is not present, go to next step.
  13. Perform after repair procedure. See AFTER REPAIR PROCEDURE  . If DTC is not present, testing is complete. If any DTC is present, go to appropriate test for diagnosis and repair.
