1. Disconnect the 2P connector from the VTEC
solenoid valve.
2. Measure resistance between the YEL (front) or
BLU/YEL (rear) terminal and body ground.
Resistance: approx 14—30 ohms
4. If filters are normal, push the VTEC solenoid valve
with your finger and check its movement.

the VTEC valve assembly from the cylinder head,
and check the VTEC valve filter for clogging.
