How do Ford cam phasers work?
How do Ford cam phasers work?
The cam phaser has two basic components: an outer sprocket connected to the timing chain and an inner rotor (connected to the camshaft) that varies the valve timing by adjusting the rotation angle of the cam. This inner rotor consists of a set of lobes, and oil fills the space between the outer housing and the lobes.
How does the phaser control the valve timing?
The phasers use directed oil pressure to manipulate camshaft position relative to the sprocket and therefore vary valve timing. Notice there is a spring on the exhaust cam phaser.
What are the cam phasers in a car?
Basically cam phasers are a portion of the VVT (variable valve timing) component of your engine. Initially it was meant to help give better gas mileage, and be more efficient, however as the vehicles aged (and some even with low mileage) the system begins to fail causing a ticking or knocking sound, which is never exactly a great experience.
Why is my cam phaser not working on my Triton?
Cam phaser issues were a common problem on certain 3 valve Ford engines, and the design has been updated since. They had a minor oil pressure problem as well. The cam phasers are used to advance and retreat cam timing. This is oil pressure controlled by variable cam timing solenoids.
How does a variable valve timing engine work?
Notice there is a spring on the exhaust cam phaser. Variable valve timing (VVT) engines have become rather common in the last decade. Different versions of VVT technology exist, but the version this article will focus on is using a phaser to manipulate camshaft position and, therefore, valve timing.

What do you need to know about camshaft phaser?
NOTE: This repair requires extensive knowledge & experience and is probably best done by a professional ASE certified automotive technician. The variable valve timing (VVT) camshaft phaser is a sprocket that will alter its position in reference to commands from the PCM for variable valve timing.
