cam phaser sensor
 

If the cam phaser is making noise, would a person change the sensor first. Or just replace the cam phaser itself.

ttt im curious to

Change the cam Phasers. The sensor will not cause it to make noise.

Do they make a whistling sound when they are going bad? My truck was making a whistling noise yesterday when is was 5 degrees out. When i would let off the gas, It would stop and then gradually start up again.

hey mine whistles to and i had the phasers priced for labour and parts $23?? yikes

How much? Can a guy do it himself without tearing the engine apart?
