Walker Products Variable Valve Timing

The Engine Variable Valve Timing Solenoid (VVT) sends oil pressure to the Variable Timing Sprocket, also referred to as VTS or Cam Phaser, allowing the Phaser to retard or advance the camshaft position. The Cam Phaser (VTS) connects the camshaft to the timing belt and keeps the timing belt in the same rotation as the crankshaft depending on the speed and load of the engine for optimum engine performance. Variable valve timing technology was introduced to increase engine performance without sacrificing fuel economy. When operating correctly, the variable valve timing system can adjust engine timing at specific RPM ranges or under various engine load situations.

Common causes of Variable Timing Solenoid failure:

• Dirty engine oil clogging the screen
• Low engine oil level
• Lack of basic maintenance
• Failed solenoid due to poor quality

Symptoms of a failing Variable Timing Solenoid may include:

• Rough idle
• Decrease in fuel economy
• Engine stumbles when going uphill or carrying load
• Loud and rough idle
• Engine knock
• Engine will not function at a high rpm
• Check Engine Light on
