VVT Solenoid

What it does
Modern engines can adjust their valve timing on the fly to make more power and better mileage. The VVT solenoid is the oil-controlled switch that makes that adjustment happen. It runs on clean engine oil — so when oil gets dirty or the solenoid screen clogs, it can't move the timing and the computer throws a timing code.

Frequently asked questions
Try anything before replacing it?
Yes — a fresh oil change with the correct grade fixes many VVT codes, because dirty oil is the usual culprit. Do that first; it's the cheapest possible fix.
