DTC Troubleshooting (cont’d)
17. Monitor the OBD STATUS for DTC P2648 in the
DTCs MENU with the HDS.
Troubleshooting is complete.
If the screen indicates FAILED, go to step 1
and recheck. If the screen indicates NOT
COMPLETED, go to step 15 and recheck.
18. Update the ECM/PCM if it does not have the latest
software, or substitute a known-good ECM/PCM
(see page 11-6).
19. Do the VTEC TEST in the INSPECTION MENU with
the HDS.
20. Check for Temporary DTCs or DTCs with the HDS.
If DTC P2648 is indicated, check for poor
connections or loose terminals at the rocker arm oil
control solenoid (VTEC 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.
If the ECM/PCM was updated, troubleshooting
is complete. If the ECM/PCM was substituted,
replace the original ECM/PCM (see page 11-284).
Does the scr een indicate PASSED?
Ar e any T empor ar y DT Cs or DT Cs indicated?

1. Turn the ignition switch ON (II).
2. Clear the DTC with the HDS.
3. Start the engine. Hold the engine speed at
3,000 rpm without load (in Park or neutral) until the
radiator fan comes on, then let it idle.
4. Check for Temporary DTCs or DTCs with the HDS.
Go to step 5.
Intermittent failure, system is OK at this time.
Check for poor connections or loose terminals at
the rocker arm oil control solenoid (VTEC solenoid
valve) and the ECM/PCM.
5. Turn the ignition switch OFF.
6. Disconnect the rocker arm oil control solenoid
(VTEC solenoid valve) 2P connector.
7. Measure resistance between rocker arm oil control
solenoid (VTEC solenoid valve) 2P connector
terminals No. 1 and No. 2.
Go to step 8.
Go to step 13.
8. Check for continuity between rocker arm oil control
solenoid (VTEC solenoid valve) 2P connector
terminal No. 1 and body ground.
Go to step 9.
Repair open in the wire between the rocker
arm oil control solenoid (VTEC solenoid valve) and
G101, then go to step 14.
9. Jump the SCS line with the HDS.
10. Disconnect ECM/PCM connector B (24P).
11. Connect rocker arm oil control solenoid (VTEC
solenoid valve) 2P connector terminal No. 2 to
body ground with a jumper wire.

12. Check for continuity between ECM/PCM connector
terminal B6 and body ground.
Go to step 20
Repair open in the wire between the ECM/
PCM (B6) and the rocker arm oil control solenoid
(VTEC solenoid valve), then go to step 14.
13. Replace the rocker arm oil control solenoid (VTEC
solenoid valve) (see page 11-324).
14. Reconnect all connectors.
15. Turn the ignition switch ON (II).
16. Reset the ECM/PCM with the HDS.
17. Do the ECM/PCM idle learn procedure (see page
11-349).
18. Check for Temporary DTCs or DTCs with the HDS.
If DTC P2649 is indicated, check for poor
connections or loose terminals at the rocker arm oil
control solenoid (VTEC 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 19.
19. Monitor the OBD STATUS for DTC P2649 in the
DTCs MENU with the HDS.
Troubleshooting is complete.
If the screen indicates FAILED, go to step 1
and recheck. If the screen indicates NOT
COMPLETED, go to step 17 and recheck.
20. Update the ECM/PCM if it does not have the latest
software, or substitute a known-good ECM/PCM
(see page 11-6).
21. Check for Temporary DTCs or DTCs with the HDS.
If DTC P2647 is indicated, check for poor
connections or loose terminals at the rocker arm oil
control solenoid (VTEC 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.
If the ECM/PCM was updated, troubleshooting
is complete. If the ECM/PCM was substituted,

1. Disconnect the VTC oil control solenoid valve 2P
connector.
2. Remove the bolt (A) and the VTC oil control
solenoid valve (B).
3. Check the VTC oil control solenoid valve strainer
for clogging. If the strainer is clogged, replace the
VTC oil control solenoid valve.
4. Note the amount of valve opening by observing the
position of the piston shoulder (A) through the
valve retard drain port. If you see the shoulder of
the piston, the valve is open and must be replaced.
