Test the VTEC Solenoid Valve:
1. Turn the ignition switch OFF
2. Disconnect the VTEC solenoid
valve 1P connector,
3. Attach the batterY Posrtrveterminal to the VTEC solenoid
valve terminal.4. Start the engine and check
the oil Pressure at engine
speed ol5,000 rPm
lrcoect the VTEC solenoid valve(see page S54)ls the pressure above 390 kPa(4.0 kgt/cm?, 57 Psi)?
Test the VTEC Pressure Switch:
With the battery Positive terminal
connected to the VTEC solenoid
valve, measure voltage between
the ECM connector terminal C10
and body ground.
ls there battery voltage above
5,000 rpm?

Inspection
1. Remove the VTEC solenoid valve assembly fromthe cylinder head. and check the VTEC solenoidvalve filter for clogging.
. lf there is clogging, replace the engine oilfilter andengine oil.

lf the filter is not clogged. push the VTEC solenoidvalve with your finger and check its movemenr.
. lf the VTEC solenoid valve is normal, check theengine oil pressure.

Rocker Arms
Removal
'1. Hold the rocker arms together with a rubber band to
prevent them from separating.
Remove the intake and exhaust rocker shaft oil con-
trol orifices, then remove the VTEC solenoid valve
and the sealing bolts.
NOTE: The shapes ofthe intake and exhaust oil con-
trol orifices are different, ldentify the parts as they
are removed to ensure reinstallation in the original
locauons.
