Hi,

I've been reading on these forums for the last few days and they've been helpful. I've had the chirping noise that other threads have attributed to the camshaft position synchronizer & sensor. It was replaced yesterday with a balkamp camshaft synchronizer, but the chirping noise is still occurring. I want to now try and replace the sensor (probably should have started with that one, first) but I am having a hard time locating it.

I thought I found it yesterday but the replacement part is different than what was pulled out of the engine, and after some digging around I realized that what I thought was the camshaft position sensor was actually the crank position sensor.

So can anyone help me locate the camshaft position sensor?

The Ford has 94,000 miles on it

Thanks for all the help, these forums have been useful.

Cmp (camshaft position sensor) bolts to the top of the camshaft synchronizer which sits in the old distributor hole under a wiring harness on the drivers side of the vulcan engine.

Wow, really? Because then that means that the camshaft sensor was replaced too because that's the part that came with the synchronizer.

This is the part that I was showed by a NAPA representative that is a camshaft sensor, so this is what I've been looking for:



THis is what I pulled out of my car thinking it was the camshaft sensor but later realized its the crankshaft sensor:


so now it appears as though the camshaft synchronizer & sensor HAVE been replaced, but the noise still persists. Could this mean that it wasn't installed correctly? I have noticed a slight improvement, but it still chirps.

Out of curiosity, do you think the crankshaft sensor could cause the chirping too?

Another issue I seem to be having now is that the check engine light is pulling through the p0171 & p0174 codes this morning.

(just for background information: for the last two month my car would have the "check engine" light soon on and off about every other week. Last month the chirping started. The last time I pulled the codes it was how I discovered this site and that it was the camshaft synchronizer. 2 weeks ago my MPG has decreased, but on my last 2 fill ups, it has gone back up to normal. So it's not consistent, just like the "check engine soon" light is not consistently on. So right now I'm only trying to focus on one thing at a time...)

Thanks a lot for you help!

That NAPA pic is NOT the CMP sensor for a Vulcan. Looks a little like the CMP for the Duratec.

On the Vulcan, the CMP is a seperate part from the shaft / syncro assy. You can replace one, the other, or both. If the "tang" in the new syncro assy isnt bent, broken, and is compatable with the new syncro shaft assy etc, the old sensor itself will not cause squeeking. The sensor itself has no moving parts.

That NAPA one is a Duratec sensor. For Vulcan should look similar with the below pic (syncronizer, sensor and alignment tool):

The recommendation here on the forum is to only use the oem motorcraft cam sync, esp. not the ill-fitting, poorly constructed dorman part. Iirc, balkamp is napas rebranded dorman part which could be (probably is) the cause of your continued squeak. As for the po171-174 codes, you have a vacuum leak(s) affecting both cylinder banks. For starters, i would check the pcv hose and clean the maf sensor with crc maf spray cleaner. You may have a vacuum diagram sticker affixed underhood to assist your search. Good luck. And yes, the napa pic is the cmp for the 3.0 duratec engine, you have the 3.0 vulcan.

Okay thanks for the help, I appreciate it! A week later, the squeeking is still happening and just today the car isn't starting on first attempt. It has only happened 3 times today so I need to let the engine cool and try and figure things out from there. :(

I appreciate the input from all!

Keep in mind that if the syncronizer shaft pin fails, you loose instantly the oil pressure. That could be the end of that engine (in several seconds of normal driving).
