Where is the VVT actuator located?
Where is the VVT actuator located?
camshaft
The VVT actuator is located on the camshaft, and is not visible without significant engine teardown.
What happens if a VVT actuator fails?
A malfunctioning VVT solenoid can prevent the valve timing from advancing or retarding as needed. As a result, the engine may exhibit performance problems, such as rough running and poor acceleration.
How much does a VVT actuator cost?
The average cost for variable valve timing actuator replacement is between $731 and $849. Labor costs are estimated between $452 and $570 while parts are priced at $279. This range does not include taxes and fees, and does not factor in your specific vehicle or unique location. Related repairs may also be needed.

How do I know if my VVT actuator is bad?
Common signs include a rough engine idle, the Check Engine Light coming on, and the engine stumbling when climbing hills or under load.
How much is it to replace the variable valve timing?
The average cost for variable valve timing control solenoid replacement is between $326 and $388. Labor costs are estimated between $138 and $175 while parts are priced between $188 and $213. This range does not include taxes and fees, and does not factor in your specific vehicle or unique location.
How does Volvo VVT work?
Basically, it varies the valve timing by shifting the phase angle of camshafts. For example, at high speed, the inlet camshaft will be rotated in advance by 30° so to enable earlier intake. This movement is controlled by engine management system according to need, and actuated by hydraulic valve gears.
Is variable valve timing good?
There are many benefits to using VVT and virtually no drawbacks. One benefit is an increase in maximum engine speed (and therefore more peak power) – as much as a 25% increase. Low speed torque is also increased, providing better handling and drivability.
What happens when a variable timing solenoid goes bad?
Rough Acceleration The main purpose of the VVT solenoid is to adjust the camshaft timing so you will have effective and smooth engine operation at all different RPMs. If it fails, you may find it causing your acceleration to become rough, and it might even cause misfires when accelerating.
