What are cam phasers f150?

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.

How can you tell if a cam phaser is bad?

Typically, worn phasers create a loud and rough idle. Often, a knocking noise is heard. In some instances, the noise is not due to wear in the phasers but rather low oil pressure due to cam bearing wear in the cylinder heads. If that is the case, the heads may need to be replaced or machined.

Can a cam phaser be fixed?

Replacing phasers will sometimes cure the problem but often rattle comes back within a few months. The sure fix to phaser problems is to lock the variable cam timing by essentially turning the phaser into a fixed timing gear. The WMS Cam Phaser Lockout kit will solve the phaser issue permanently.

What causes cam phaser knock?

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.

What is a cam phaser on a Ford truck?

Ford began using computer controlled camshaft gears, known as cam phasers, in their modular 3-valve truck engines in 2004 to allow for variable cam timing. The variable valve timing system operates when the engine computer (PCM) sends oil pressure to one or the other chamber of the phaser via cam timing solenoids.

What are cam phasers in a truck?

What exactly IS a Cam Phaser, you ask? Ford’s Cam Phasers are specially designed, computer-controlled cam gears for all 2005 and newer Ford Modular 3 Valve engines that have the ability to adjust camshaft position while the engine is running. Since the modular engine uses two camshafts, two Cam Phasers are used.

Where is the cam phaser located?

Phasers can be found just on the exhaust cam or on both the intake and exhaust cams. The alteration of camshaft position changes the cam centerline and the lobe separation angle between intake and exhaust cams. This allows engineers to improve fuel economy and power while continuing to meet emissions standards.

What are phasers on a truck?

What are cam phasers? Ford’s cam phasers are specially designed, computer-controlled cam gears that have the ability to adjust camshaft position (centerline ” advance or retard) while the engine is running. They are used on all 2005 and newer, Ford 3 Valve Modular engines.

Will bad cam phasers throw a code?

It will go into safe (or limp) mode, which will in most cases, and stop the engine from going over a certain RPM. It will also throw a code and illuminate the check engine light.

What are timing phasers?

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.

What does a cam phaser lockout do?

Using a phaser lockout that locks the cam phaser into a fixed position prevents any movements that could rattle.
