Subject: Camshaft Position Sensor R&R for '99+. Author: Magnum : member since January, 2004 : 3968 posts Posted on: 2005-03-31 20:38:36

I searched and found a lot of info on this replacement for 98, 97 and even a 5'er, but nothing for a '99+. So I did a short pictorial to have around, everybody likes pics, right.

Story: My SES light was on and off, I finally caught it and reported code P0340.

This was easy, did it on my lunch hour. The only thing is space on passenger side, there isn't much. BTW, here's a .pdf for printing if you like [yes, I had some free time this evening].

Here is what the Camshaft Position Sensors x 2 [for '99+] & the O-Rings look like.


Start out by removing this cover, as shown.


Next loosen the “hose clamps” and unclip the “clips”.


Now remove the MAF sensor. I didn’t unplug the wiring on top of the MAF, as it is long enough to slide it to the side.


Remove this bolt, from what I can tell it secures the MAF from floating around.


Now remove the CPS, there isn’t much room, but I had luck loosening it and then unscrewing by hand. It’s a 5mm allen screw if you have trouble seeing photo text.


To remove the sensors plug, simply push in on this metal clip and pull off.


Passenger side “bank 1” done.


Now let’s move on to Drivers side “bank 2”.


Remove this 5mm Allen Screw.


Dual picture for ease, but push in the metal clip to remove this plug side.


Replace the “Acoustic Cover”.


Now’s a good time to get in and reset your Service Engine Soon Light with your favorite reset tool, You’re done! Easy stuff......

It could be my imagination, but I do seem to notice my car seems to have less hesitation off the line and idles a bit better. I will be curious to see if this help the starting issue I had leading up to my SES light coming on. Time will tell, but more new parts none the less!
