VTEC/VTC
DTC Troubleshooting (cont’d)
13. Inspect the VTC actuator (see page 6-10).
Go to step 14.
Replace the VTC actuator (see page 6-33),
then go to step 14.
14. Turn the ignition switch ON (II).
15. Reset the ECM/PCM with the HDS.
16. Clear the CKP pattern with the HDS.
17. Do the ECM/PCM idle learn procedure (see page
11-349).
18. Do the CKP pattern learn procedure (see page 11-5).
19. Do the VTC TEST in the INSPECTION MENU with
the HDS.
20. Check for Temporary DTCs or DTCs with the HDS.
If DTC P0011 is indicated, check for poor
connections or loose terminals at the VTC oil
control solenoid valve 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.
Go to step 21.
21. Monitor the OBD STATUS for DTC P0011 in the
DTCs MENU with the HDS.
Troubleshooting is complete.
If the screen indicates FAILED, check for poor
connections or loose terminals at the VTC oil
control solenoid valve and the ECM/PCM, then go
to step 1. If the screen indicates NOT COMPLETED,
go to step 19 and recheck.
Is the V T C actuator OK ?
Ar e any T empor ar y DT Cs or DT Cs indicated?
Does the scr een indicate PASSED?

Intermittent Interruption
(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. Turn the ignition switch OFF.
4. Disconnect CMP sensor A 3P connector.
5. Turn the ignition switch ON (II).
6. Measure voltage between CMP sensor A 3P
connector terminal No. 3 and body ground.
Go to step 7.
Check the No. 4 ACG (10 A) fuse in the under-
dash fuse/relay box. If the fuse is OK, repair open in
the wire between CMP sensor A and the No. 4 ACG
(10 A) fuse.
7. Measure voltage between CMP sensor A 3P
connector terminal No. 1 and body ground.
Go to step 8.
Go to step 10.
8. Measure voltage between CMP sensor A 3P
connector terminals No. 2 and No. 3.
Go to step 9.
Repair open in the wire between CMP sensor
A and G101.

9. Substitute a known-good CMP sensor A and
recheck.
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 original CMP sensor A (see page
11-323).
10. Measure voltage between ECM/PCM connector
terminal A25 and body ground.
Repair open in the wire between the ECM/
PCM (A25) and CMP sensor A.
Go to step 11.
11. Turn the ignition switch OFF.
12. Disconnect ECM/PCM connector A (31P).
13. Check for continuity between ECM/PCM connector
terminal A25 and body ground.
Repair short in the wire between the ECM/
PCM (A25) and CMP sensor A.
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).
