(J35A6 engine, J35A7 engine ('07 model))
DTC P0385:
CKP Sensor B No Signal
(J35A6 engine, J35A7 engine ('07 model))
NOTE:
- Before you troubleshoot, record all freeze data and any on-board snapshot, and review the general troubleshooting information Initial Inspection and Diagnostic Overview.
- Information marked with an asterisk (*) applies to CKP sensor B.
1. Turn the ignition switch to ON (II).
2. Clear the DTC with the HDS.
3. Start the engine.
4. Check for Pending or Confirmed DTCs with the HDS.
Is DTC P0335 and/or P0385 indicated?
YES -
Go to step 5.
NO -
Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at CKP sensor A/B and the PCM.�
5. Turn the ignition switch to LOCK (0).
6. Disconnect the CKP sensor A/B 6P connector CKP Sensor Replacement (Except J35A7).
7. Turn the ignition switch to ON (II).
8. Measure the voltage between CKP sensor A/B 6P connector terminal No. 6 (No. 3)* and body ground.
Is there battery voltage?
YES -
Go to step 9.
NO -
Repair open in the wire between CKP sensor A/B and PGM-FI main relay 1 (FI MAIN), then go to step 18.
9. Measure the voltage between CKP sensor A/B 6P connector terminal No. 5 (No. 2)* and body ground.
Is there about 5 V?
YES -
Go to step 10.
NO -
Go to step 11.
10. Measure the voltage between CKP sensor A/B 6P connector terminals No. 4 (No. 1)* and No. 6 (No. 3)*.
Is there battery voltage?
YES -
Go to step 16.
NO -
Repair open in the wire between CKP sensor A/B and G101, then go to step 18.
11. Turn the ignition switch to LOCK (0).
12. Jump the SCS line with the HDS.
13. Disconnect PCM connector B (49P).
14. Check for continuity between PCM connector terminal B45 (B44)* and CKP sensor A/B 6P connector No. 5 (No. 2)*.
Is there continuity?
YES -
Go to step 15.
NO -
Repair open in the wire between the PCM(B45 (B44)*) and CKP sensor A/B, then go to step 18.
15. Check for continuity between PCM connector terminal B45 (B44)* and body ground.
Is there continuity?
YES -
Repair short in the wire between the PCM(B45 (B44)*) and CKP sensor A/B, then go to step 18.
NO -
Go to step 24.
16. Turn the ignition switch to LOCK (0).
17. Replace CKP sensor CKP Sensor Replacement (Except J35A7).
18. Reconnect all connectors.
19. Turn the ignition switch to ON (II).
20. Reset the PCM with the HDS.
21. Do the PCM idle learn procedure PCM Idle Learn Procedure.
22. Do the CKP pattern clear/CKP pattern learn procedure Initial Inspection and Diagnostic Overview.
23. Check for Pending or Confirmed DTCs with the HDS.
Is DTC P0335 and/or P0385* indicated?
YES -
Check for poor connections or loose terminals at CKP sensor A/B and the PCM, then go to step 1.
NO -
Troubleshooting is complete. If any other Pending or Confirmed DTCs are indicated, go to the indicated DTC's troubleshooting.�
24. Reconnect all connectors.
25. Update the PCM if it does not have the latest software PCM Update, or substitute a known-good PCM Initial Inspection and Diagnostic Overview.
26. Check for Pending or Confirmed DTCs with the HDS.
Is DTC P0335 and/or P0385* indicated?
YES -
Check for poor connections or loose terminals at CKP sensor A/B and the PCM. If the PCM was updated, substitute a known-good PCM Initial Inspection and Diagnostic Overview, then recheck. If the PCM was substituted, go to step 1.
NO -
If the PCM was updated, troubleshooting is complete. If the PCM was substituted, replace the original PCM Service and Repair. If any other Pending or Confirmed DTCs are indicated, go to the indicated DTC's troubleshooting.�
