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.

What does the exhaust camshaft position actuator do?

The camshaft position actuator solenoid valve controls the oil flow to the actuator, which in turn, advances or retards the camshaft. Solenoid operation is controlled by the car’s primary computer, also known as the powertrain control module or PCM.

What happens when a camshaft actuator goes bad?

A failing camshaft position sensor begins losing its ability to quickly transfer data. Mismatched fuel delivery and ignition timing, even if off by a few milliseconds, will cause your vehicle to sputter, accelerate poorly, lack power, stall or even shut off.

What causes a camshaft actuator to go bad?

The camshaft position sensor gathers information about the vehicle’s camshaft speed and sends it to the vehicle’s engine control module (ECM). Over time, the camshaft position sensor can fail, or become worn down, due to accidents or normal wear and tear.

Can you drive with a bad camshaft position actuator solenoid?

Yes, it is safe to drive with a bad camshaft sensor. If a camshaft position sensor is not repaired, then you will likely experience more and more issues with your vehicle’s ignition system that could lead up to very expensive repairs.

What is a camshaft actuator?

A camshaft actuator is a mechanical or electronic device that is mounted on the camshaft gear. Its purpose is to slightly advance or retard the timing of when the camshaft opens or closes the intake and/or exhaust valves.

How do you know if your camshaft actuator is bad?

A glowing check engine light, stalling, poor acceleration and bad fuel mileage are all possible signs your camshaft position sensor may be failing. Gone are the days of carburetors and distributors, replaced by a variety of sensors that help a car’s computer get the maximum performance out of the engine.
