One or more camshaft actuators—also known as camshaft phasers—act as the heart of the VVT system. When conditions are correct, the phasers alter the position of the camshafts to adjust the engine’s valve timing. Although camshaft phasers sound great in theory, they’re a common failure point on many modern engines.
What happens when a cam phaser goes bad?
When a cam phaser goes bad, the Variable Control Timing (VCT) solenoids would be destroyed, and the engine control unit (ECU) would no longer be able to control the phasers. When this happens, the engine’s timing would be affected and could lead to excessive phaser noise.
What does a camshaft phaser do?
The phaser cavity changes the valve timing by rotating the camshaft slightly from its initial orientation, which results in the camshaft timing being advanced or retarded. The PCM adjusts the camshaft timing depending on factors such as engine load and RPM.

When a cam phaser goes bad they will almost always do several things.
Why do cam phasers make noise?
The cam phasers are used to advance and retreat cam timing. This is oil pressure controlled by variable cam timing solenoids. … If the pressure drops due to a malfunctioning part, it will cause a knocking noise. Basically, a locking pin keeps oil thin at idle, and the problem goes away when you start driving.
Does a 2004 f150 4.6 have cam phasers?
