• Description:

  A variable valve timing solenoid or VVT (10921AA231) is in charge of managing the oil flow based on the engine speed and load of your car. The VVT solenoid ensures optimal fuel efficiency and engine performance. This component gauges the needs of your engine based on the oil pressure as it controls which camshafts move to open or close specific engine valves. The VVT solenoid also manages the proper lubrication of the variable valve timing chain and gear assembly of your engine.
  

  However, this component is still prone to wear and tear. If your engine oil is full of debris and foreign particles, it can clog up the chambers from the solenoid to the gears and VVT chain. If the VVT solenoid is blocked, the timing chain and gear can wear or break faster due to the lack of proper lubrication. Other signs of a failing VVT solenoid include rough engine idling from fluctuating engine RPM and reduced fuel economy.
