What are the symptoms of a bad VVT actuator?

Symptoms of a Bad or Failing Variable Valve Timing (VVT) Solenoid

  • Check Engine Light comes on. Since today’s modern cars are controlled by an Engine Control Unit (ECU), virtually all individual components are monitored by the ECU.
  • Engine oil is dirty.
  • Rough engine idle.
  • Decrease in fuel economy.

Where is the variable valve timing actuator?

camshaft
The variable valve timing actuator is one of several critical components, and is located on the camshaft. It receives a signal from the engine control module to advance or retard the timing in small increments.

How is the variable valve timing VVT camshaft actuator controlled?

This movement is controlled by engine management system according to need, and actuated by hydraulic valve gears. Note that cam-phasing VVT cannot vary the duration of valve opening. It just allows earlier or later valve opening. Earlier open results in earlier close, of course.

Can you drive with a bad variable valve timing actuator?

Can You Drive with a Bad VVT Solenoid? Even though you may technically be able to continue driving with a bad VVT solenoid, the issue can cause damage to additional parts, such as the VVT actuator. So, you should address the issue as soon as possible.

How much does it cost to replace a VVT actuator?

Replacing one should cost about $20 to $40 in labor and $180 to $250 in parts depending on the cost of labor and parts in Your area. That gives You a total price range of $200 to $290 for the job. The VTC actuator in Your Honda has the job of keeping the intake valve timing accurate.

Is variable valve timing good?

Benefits of VVT 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.
