Variable Valve Timing Solenoid: Testing and Inspection

1. Disconnect the 1 pin connector from the Variable Valve Timing and Valve Lift Electronic Control System (VTEC) solenoid valve.

VTEC Solenoid Resistance Check:

2. Measure resistance between the terminal and body ground.

Resistance: 14 - 30 ohms

Checking For Filter Clogging:

3. If the resistance is within specifications, remove the VTEC solenoid valve assembly from the cylinder head, and check the VTEC solenoid valve/O-ring filter for clogging.

If there is clogging, replace the engine oil filter and the engine oil.

Checking For Free Movement Of The Valve:

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.
