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.).

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
solenoid valve filter, the engine oilfilter, and the
engine oil.

4. Align the quick-connect fittings with the line (A).
and align the retainer (B) locking pawls with the
connector {C) grooves. Then press the quick-
connect fittings onto the line until both retainer
pawls lock with a clicking sound.
NOTE; lf it is hard to connect, put a small amount of
new engine oil on the line end.
Connection with new retainer:
Reconnection to existing retainer:
5. lvlake sure the connection is secure and that the
pawls are firmly locked into place; check visually
and by pulling the connector.
6. Reconnectthe negative cable to the battery, and
turn the ignition switch ON (ll). The fuel pump will
run for about 2 seconds, and fuel pressure will rise
Repeat 2 or 3 times, and check that there are no
fuel leaks.

Transmission Fluid Inspection and
Replacement
'1. Park the vehicle on level ground, and turn the
engine OFF.
2. Remove the oilfiller plug (A) and washer (B), check
the condition of the fluid, and make sure the fluid is
at the proper level (C).
lf the transmission fluid is diny, remove the drain
plug (D) and drain the fluid.
A44 N.m{4.5 kgt.m,33 rbr.ftl
Reinstall the drain plug with a new washer, and
refill the transmission fluid to the proper level.
Oil Capacity
1.5 0 (1.6 US (F) at tluid change
1.7 0 {1.8 US qt) at overhaul
Always use Honda Manual Transmission Fluid
(MTF). Using motor oil can cause stiffer shifting
and noise because it does not contain the proper
additives.
Reinstall the oil filler plug with a new washer.5.

Back-Up Light Switch Test
1. Disconnectthe back-up light switch (A) connector.
Check for continuity between the back up light
swilch 2P connector No. 1 and No.2 terminals.
There should be continuity when the shift lever is in
reverse.
lf necessary, replace the back-up light switch.
Apply liquid gasket (P/N 08718-0001), and install it
on the transmission housing.
