11. Measure voltage between ECM/PCM connector

terminal A19 and body ground.

Repair open in the wire between the ECM/

PCM (A19) and CMP sensor A, then go to step 18.

Go to step 12.

12. Turn the ignition switch OFF.

13. Jump the SCS line with the HDS.

14. Disconnect ECM/PCM connector A (31P).

15. Check for continuity between ECM/PCM connector

terminal A19 and body ground.

Repair short in the wire between the ECM/

PCM (A19) and CMP sensor A, then go to step 18.

Go to step 24.

16. Turn the ignition switch OFF.

17. Replace CMP sensor A (see page 11-323).

18. Reconnect all connectors.

19. Turn the ignition switch ON (II).

20. Reset the ECM/PCM with the HDS.

21. Do the ECM/PCM idle learn procedure (see page

11-349).

22. Start the engine.

23. Check for Temporary DTCs or DTCs with the HDS.

If DTC P0340 is indicated, check for poor

connections or loose terminals at CMP sensor A
and the ECM/PCM, then go to step 1. If any other
Temporary DTCs or DTCs are indicated, go to the
indicated DTC’s troubleshooting.

Troubleshooting is complete.

24. Update the ECM/PCM if it does not have the latest

software, or substitute a known-good ECM/PCM
(see page 11-6).

25. Check for Temporary DTCs or DTCs with the HDS.

If DTC P0340 is indicated, check for poor

connections or loose terminals at CMP sensor A
and the ECM/PCM, then go to step 1. If any other
Temporary DTCs or DTCs are indicated, go to the
indicated DTC’s troubleshooting.

If the ECM/PCM was updated, troubleshooting

is complete. If the ECM/PCM was substituted,
replace the original ECM/PCM (see page 11-284).

Wire side of female terminals

Is ther e about 5 V ?

Is ther e continuity?

CMP Sensor A and CKP Sensor

Incorrect Phase Detected
(2002-2004 models)

1. Reset the ECM/PCM (see page 11-4).

2. Start the engine.

Go to step 3.

Intermittent failure, system is OK at this time.

Check for poor connections or loose terminals at
CMP sensor A and the ECM/PCM.

3. Check the VTC oil control solenoid valve (see page

11-321).

Go to step 4.

Clean the VTC oil control solenoid valve, or

replace it (see page 11-321).

4. Remove the head cover, and check the cam chain

for damage or looseness (see page 6-25).

Go to step 5.

Replace the cam chain (see page 6-14).

5. Check the VTC actuator (see page 6-10).

Update the ECM/PCM if it does not have the

latest software, or substitute a known-good ECM/
PCM (see page 11-6), then recheck. If the symptom/
indication goes away with a known-good ECM/PCM,
replace the original ECM/PCM (see page 11-284).

Replace the VTC actuator.

Is DT C P0341 indicated?

Is the V T C oil contr ol solenoid valve OK ?

Is the cam chain OK ?

Is the V T C actuator OK ?

VTEC/VTC

DTC Troubleshooting (cont’d)

CMP Sensor A and CKP Sensor

Incorrect Phase Detected
(2005-2006 models)

1. Turn the ignition switch ON (II).

2. Clear the DTC with the HDS.

3. Test-drive at a steady speed between 19

38 mph

(30

60 km/h) for 10 minutes.

4. Check for Temporary DTCs or DTCs with the HDS.

Go to step 9.

Go to step 5.

5. Do the VTC TEST in the INSPECTION MENU with

the HDS.

Go to step 6.

Go to step 9.

6. Test-drive at a steady speed between 19

38 mph

(30

60 km/h) for 10 minutes.

7. Check the VTC STATUS in the DATA LIST with the

HDS.

Go to step 8.

Go to step 6 and recheck.

8. Monitor the OBD STATUS for DTC P0341 in the

DTCs MENU with the HDS.

Go to step 9.

If the screen indicates PASSED, intermittent

failure, system is OK at this time. If the screen
indicates NOT COMPLETED, go to step 6 and
recheck.

9. Turn the ignition switch OFF.

10. Test the VTC oil control solenoid valve (see page

11-321).
