Engine Oil Filter (3/4-turn type)
1. Remove the oil filterwiththesDecial tool.
2. Inspect the threads {A) and rubber seal (B) on the
new filter. Wipe off the seat on the engine block,
then apply a light coat of oil to the filter rubber seal.
Use only filters with a built-in bypass system.
Installthe oilfilter by hand.
After the rubber seal seats, tighten the oil filter
clockwise with the special tool.

Did the engine stall or run rough?
YES Test-drive at a steady speed between
20 40 mph (30 60 km/h) for 10 minutes.
lf temporary DTC P00'l 1 is indicated, update the
ECIVI if it does not have the latest software, or
substitute a known-good ECM, then recheck (see
page 11-6). lf the symptom/indication goes awaywith a known-good ECM, replace the original
ECM. !
NO Go to step 14.
Check the VTC actuator (see page 6,8).
ls the VTC actuatot OK?
YES Remove the auto-tensioner (see page 4-281,
and clean or replace the VTC oil strainer. Update
the ECI\4 if it does not have the latest software, orsubstitute a known-good ECM, then recheck (see
page 11-6). lf the symptom/indication goes awaywith a known-good ECM, replace the original ECM.

WC OilControl Solenoid Valve Removal/Test
1. Remove the WC oilcontrol solenoid valve (A).
NOTE: lnstall the valve in the reverse order of
removal with a new o-ring (B), then check these
tlems:
Clean and dry the VTC oil control solenoid valve
mating surface.
Coat the O-ring with engine oil.
Do not install the VTC oilcontrol solenoid valve
while wearing fibrous gloves,
Be careful not to contaminate the cylinder head
openrng.
Check the VTC oil control solenoid valve filter for
clogging. lf it is clogged, replace the VTC oil control
solenoid valve.
Check the clearance between the port (advance
side) and the valve. The clearance (A) should be at
least 2.8 mm (1/8 in.).
Connect the battery positive terminal to VTC oil
control solenoid valve 2P connector terminal No. 2.

WEC Solenoid Valve Removal/
Inspection
1.Disconnect the VTEC solenoid valve 2P connector.
Measure resistance between VTEC solenoid valve
connector terminals No. 1 and No. 2.
Resistance: 14-30 Q
3. lf the resistance is within specifications, remove the
VTEC solenoid valve assemblv (A)from the
cylinder head, and check the VTEC solenoid valve
filter (B)for clogging. lf it is clogged, replace the
