Solenoid valve for variable valve timing

Caution: Do not apply 12 V voltage to the solenoid valve from a self-contained power source.

1. Inspect the valve, look for:

• damage to the wiring connector;
• accumulation of dirt in the undercut area near the pin;
• deposits of oil sludge on the pin, which can lead to sticking and / or a decrease in the amount of stroke of the pin.

2. Turn the solenoid valve with the pin up and measure (A) protrusion of the pin. Record the result.



3. Turn the valve upside down and measure the protrusion of the axle again.



4. Calculate the stroke of the pin: the stroke of the pin should be 3.0-5.5mm. If not, replace the solenoid valve assembly.
