Now modern cars have advanced variable valve timing that is using electronic technology for applying the variable electronic signals from the ignition system. Subsequently, the variable valve timing solenoid is used for controlling the oil flow to the VVT system to run the engine with a heavy load. When the VVT solenoid is failing in Volvo XC90, you will notice the signs given in the following slide.

2. In your car, the
variable valve timing
(VVT) is used for
applying the variable
electronic signals from
the ignition system.
3. VVT solenoid in Volvo
can control the flow of
oil to the VVT system
to run the engine with
a heavy load such as:
• Traveling up hills
• Carrying additional
weight
4. Moreover, it can
lubricate the variable
valve timing chain and
gear assembly by
providing the right
amount of oil.
5. When the VVT
solenoid is failed, the
timing chain and gear
assembly are worn out
prematurely.
9. If the oil is
contaminated, then it
will clog the
passageway from the
VVT solenoid and could
damage the:
• Gear drive
• VVT chain
• VVT solenoid
11. For maximizing the
fuel mileage, the VVT
system ensures that its
valves are opened and
closed at the right
time.
12. If the VVT solenoid is
failed, then the entire
system of the car is
compromised and
reduces the fuel
mileage.
14. Thus, the VVT system
is activated in your
Volvo when the engine
is running at higher
RPM or in load-
bearing situations.
15. If the VVT solenoid
failed, then the VVT
gear needs additional
engine oil that can
cause rough engine
idling.
17. Like the other engine
problems, the failed
variable valve timing
solenoid will also
activate the check
engine light.
18. When it happens, you
have to contact a
reputed auto repair
shop for checking the
VVT solenoid of the
car.
20. Neglecting the damaged
variable valve timing
solenoid in the Volvo is
causing numerous problems
such as:
• Reducing the engine
performance
• Decreasing the fuel mileage
• Wearing out the engine
components
21. If the VVT solenoid in
your Volvo XC90 is
failed, then consult a
mechanic to diagnose
and repair the
solenoid immediately.
