Component Tests and General Diagnostics

1. Disconnect the 1P connector from the VTEC Solenoid Valve.

Measuring Resistance:

2. Measure resistance between the Terminal and body ground.

Resistance: 14 - 30 Ohms

VTEC Solenoid Valve Filter:

3. If the resistance is within specifications, remove the VTEC Solenoid Valve assembly from the Cylinder Head, and check the VTEC Solenoid Valve filter/O-ring for clogging. If there is clogging, replace the Engine Oil Filter and the Engine Oil.

Checking Movement:

4. If the Filter is not clogged, push the VTEC Solenoid Valve with your finger and check its movement. If the VTEC Solenoid Valve is normal, check the Engine Oil pressure.
