Diagnostic Procedures

WARNING: This page is about a different car, the 2000 Isuzu Hombre. However, it is still accessible from the selected car via links, so may be relevant.
  1. Perform On-Board Diagnostic II (OBD-II) System Check. See SELF-DIAGNOSTICS - INTRODUCTION article. Retrieve and record FREEZE FRAME and/or FAIL RECORDS data for each DTC set. Go to next step.
  2. Disconnect CKP sensor harness connector. Connect a test light between engine ground and ignition feed circuit (Pink wire) at CKP sensor. Turn ignition on, engine off. If test light comes on, go to next step. If test light does not come on, go to step  8.
  3. Turn ignition off. Connect test light between battery voltage and sensor ground circuit (Purple wire) at CKP sensor. If test light comes on, go to next step. If test light does not come on, go to step  7.
    NOTE: CKP sensor ground circuit may also be referred to as CKP sensor signal low circuit or reference low circuit.
  4. Disconnect VCM Blue connector. Using a test light connected to battery voltage, probe CKP sensor 3x signal circuit (Yellow wire) at CKP sensor harness connector. If test light comes on, go to step  10. If test light does not come on, go to next step.
    NOTE: The CKP sensor 3x signal circuit may also be referred to as CKP sensor signal high circuit or reference high circuit.
  5. Reconnect VCM Blue connector. Install Gray jumpers from Connector Tester Kit (J35616-A) between CKP sensor and CKP sensor harness connector. Start engine. Connect a DVOM (set to duty cycle) between CKP sensor 3x signal circuit (Yellow wire) and sensor ground circuit (Purple wire). If duty cycle is less than 40 percent, go to step  11. If duty cycle is not less than 40 percent, go to next step.
  6. Check for faulty connection at CKP sensor and go to step  12.
  7. Check for open in CKP sensor ground circuit (Purple wire). If open is found, go to step  12. If circuit is okay, go to step  9.
  8. Check for open or short to ground in CKP sensor 3x signal circuit (Yellow wire) and go to step  12.
  9. Check for faulty connection at VCM. If faulty connection is found, go to step  12. If connection is okay, go to step 13)  .
  10. Repair short to ground in CKP sensor 3x signal circuit (Yellow wire). After repairs, go to step  14.
  11. Replace CKP sensor. After replacing sensor, go to step  14.
  12. Repair circuit(s) as necessary. After repair, go to step  14.
  13. Replace VCM. Program replacement VCM. See PROGRAMMING . After replacing VCM, go to next step.
  14. Using scan tool, select DTC, CLEAR INFO function. Start engine and allow it to reach operating temperature. Using scan tool, select DTC, SPECIFIC function and enter DTC P0337. Operate vehicle within conditions required to set DTC. If scan tool displays RAN AND PASSED, go to next step. If scan tool does not display RAN AND PASSED, return to step  2.
  15. Using scan tool, select Read and Record INFO, REVIEW INFO function. If any undiagnosed DTCs are displayed, diagnose affected DTCs. If no DTCs are displayed, system is okay.
