VVT Solenoid (Camshaft Control Valve)
The VVT solenoid controls oil flow to the camshaft phaser.
What is VVT Solenoid (Camshaft Control Valve)?
The control unit drives it. Dirty oil blocks it. Faults set timing codes. Many solenoids have a fine mesh screen that can clog with sludge. Checking oil level and condition is the first step when timing codes appear. Live data showing desired and actual camshaft position helps decide whether the solenoid, the phaser or the timing chain is at fault. A solenoid can often be tested by applying power briefly and listening for a click, following service information. Some engines have one solenoid per camshaft.
How it works
A valve directs oil pressure.
Why it matters for your car
Use correct oil. Clean screens if fitted.
