16. Remove the rocker arm oil pressure switch (VTEC

oil pressure switch) (A), and install the special tools
as shown, then install the rocker arm oil pressure
switch (VTEC oil pressure switch) in the pressure
gauge adapter (B).

NOTE: Install the parts in the reverse order of
removal with a new O-ring.

17. Reconnect the rocker arm oil pressure switch

(VTEC oil pressure switch) 2P connector.

18. Start the engine. Hold the engine speed at

3,000 rpm without load (in Park or neutral) until the
radiator fan comes on.

19. Check the oil pressure at engine speeds of 1,000

and 2,000 rpm. Keep the measuring time as short
as possible (less than 1 minute) because the engine
is running without load.

Check for air in the fuel line, then go to step

20.

Inspect the VTEC system (see page 6-7), then

go to step 20.

20. Turn the ignition switch ON (II).

21. Reset the PCM with the HDS.

22. Clear the CKP pattern with the HDS.

23. Do the PCM idle learn procedure (see page 11-273).

24. Do the CKP pattern learn procedure (see page 11-4).

25. Test-drive the vehicle for several minutes in the

range of these recorded freeze data parameters:

• ENGINE SPEED
• VSS
• REL TP SENSOR
• CLV (calculated load value)
• ECT SENSOR 1
• APP SENSOR

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

Check for poor connections or loose

terminals at the ignition coil, the injector, and the
PCM, then go to step 1.

Go to step 27.

27. Monitor the OBD STATUS for DTC P0301, P0302,

P0303, P0304, P0305, or P0306 in the DTCs MENU
with the HDS.

Troubleshooting is complete. If any other

Temporary DTCs or DTCs were indicated in step 26,
go to the indicated DTC’s troubleshooting.

If the screen indicates FAILED, check for poor

connection or loose terminals at the ignitions coil,
the injector, and the PCM, then go to step 1. If the
screen indicates EXECUTING, keep driving until a
result comes on. If the screen indicates OUT OF
CONDITION, go to step 25.

Is the oil pr essur e below 49 kPa ( 0.5 kgf / cm ,
7 psi)?

Is DT C P0300 and any combination of DT C P0301,
P0302, P0303, P0304, P0305, or P0306
indicated?

Does the scr een indicate PASSED?

NOTE: Before you troubleshoot, record all freeze data
and any on-board snapshot, and review the general
troubleshooting information (see page 11-3).

1. Turn the ignition switch ON (II).

2. Clear the DTC with the HDS.

3. Start the engine, and let it idle without load for

2 minutes (in Park or neutral).

4. Monitor the OBD STATUS for DTC P0301, P0302,

P0303, P0304, P0305, or P0306 in the DTCs MENU
with the HDS.

Go to step 9.

If the screen indicates PASSED, go to step 4. If

the screen indicates EXECUTING, keep idling until
a result comes on. If the screen indicates OUT OF
CONDITION, wait for several minutes, and recheck.

5. Check the CYL1 MISFIRE, CYL2 MISFIRE, CYL3

MISFIRE, CYL4 MISFIRE, CYL5 MISFIRE, and/or
CYL6 MISFIRE in the DATA LIST for 10 minutes
with the HDS.

Go to step 9.

Go to step 6.

6. Test-drive the vehicle for several minutes in the

range of these recorded freeze data parameters:

• ENGINE SPEED
• VSS
• REL TP SENSOR
• CLV (calculated load value)
• GEAR POSITION
• ECT SENSOR 1

7. Monitor the OBD STATUS for DTC P0301, P0302,

P0303, P0304, P0305, or P0306 in the DTCs MENU
with the HDS.

Go to step 9.

If the screen indicates PASSED, go to step 8. If

the screen indicates EXECUTING, keep driving until
a result comes on. If the screen indicates OUT OF
CONDITION, go to step 6.

8. Check the CYL1 MISFIRE, CYL2 MISFIRE, CYL3

MISFIRE, CYL4 MISFIRE, CYL5 MISFIRE, and/or
CYL6 MISFIRE in the DATA LIST for 10 minutes
with the HDS.

Go to step 9.

Intermittent failure, the system is OK at this

time. Check the fuel and ignition system circuit
connectors for loose wires or poor connections.

9. Turn the ignition switch OFF.

10. Exchange the ignition coil from the problem

cylinder with one from another cylinder.

11. Reconnect all connectors.
