Racerguy, thanks for the quick response. I'll see if I can get it from the passenger side. Looks like I might have to move some electrical harnass wires out of the way. Maybe thats whats blocking most of it.
Thanks

I couldn't get to my camshaft postioning sensor without removing the plenum, even then it was under a harnass of wires. Anyways, the bottom line is that there are 3 different types of camshaft postioning sensor's for a 1995 Ford Ranger. The one I have does not just involve changing the top cap (being the camshaft positioning sensor). Mine is the CPS complete with synchronizer and stator. The Ford Dealer here cannot even get the Ford part. I can get an after market one (item # J12K073) for $600.00.

My question is:What if I just continue to drive it like this? What could happen? Would I just not get as good of gas mileage. Right now it just idles up and down alittle. The prevous owner says the service light has been on for the last 10- years that he has had it.

I'm looking at just putting it back together and driving it as is. If anybody else has driven it like this, I would like to hear some feedback on this.
Thanks

That doesn't look like an OHV 4.0L.

Are you sure yours isn't a SOHC 4.0L? If it is, then it will not have a cam synchro assembly like the OHV.

You are correct, its a SOHC. I dont know what that means with respect to the car.

Im trying to replace it due to a P0340 error- "Camshaft Position Sensor Circuit Malfunction".

On the 4.0L SOHC engine (VIN E), the Camshaft Position Sensor is triggered by the high-point mark on the left-hand camshaft. It is mounted to the valve cover.

Thanks for the replys and link

Im confused. The part I picked up does not look like the one in the drawing you linked. The drawing has only 1 bolt, but the replacement I purchased has 2.

Car Part Wholesale - Auto Parts and Accessories Catalog - Camshaft Position Sensor For 1996 Ford Explorer XLT 6 Cyl 4.0L

This link shows what I purchased. Ive also verified this part at 2 different auto parts places. What am i missing- are they selling me the wrong part?

1995 4.0 OHV Ranger Camshaft Synchronizer

Dealer says synchro. needs rpl at $1,200. $300 for more recent model that must be modified as the part for my 1995 is no longer available, plus $900 in labor. The only symptom I've noticed other than not great MPG, is an intermittent metallic whine or squeal. My CEL has not come on to indicate any sort of problem. Any INFORMED opinions on what (if any) actions I should take?
I've read the 3.0 & 4.0 threads on this matter. Thanks for your response.

Follow up.

With the diagram you attached, I easily located what I think is the part. The first photo has me pointing to the part, on the drivers side valve cover. The second photo shows the original part on the left , and the Advance Auto part on the right. Obviously, they are not the same.

So, do I have the correct original or replacement? This is crazy- i called the local Ford dealership, and he wasnt any help either. Im thinking the part I removed is not the correct part- isnt the CPS supposed to be riding on a part like a distributor? The original part is more like a plug- sort of like a pcv valve.Name:  IMG_2633.jpg

mdfan, the problem I think you might be having is that the first year of the SOHC was supposedly 1997. Try telling the parts people that you have a '97 4.0L Single Overhead Camshaft (SOHC) engine and you'll get the right part.

I have read before that the '95 synchro assembly is indeed different, and that it's a little harder to find these days. I've also heard that you can find re-manufactured ones on eBay. Or you could check the local wrecking yards for a '95 4.0L Ranger.

$900 for labor is a joke. If you can find the correct part, you can put it in yourself. You'll have to remove the upper intake to get at it. For guidance on that, see: Replacing Ford 4.0L Upper Engine Gaskets

You are a genius.

FWIW. This is/was my parents car, and they recently gave it to me. Door sticker says its manufactured Sept 06. Called Dad to ask if he every buys 97 parts, and he says "yes, its a 97".

Intake manifold back on. Picking up the correct part in the am. Thanks for the help!

A genius? Try telling that to.... well ...never mind. Glad I could help. Let's hope the new sensor clears up that P0340 code.

It sounds like you have what they call a Model Year (MY) 1997 Explorer, equipped with one of the first generation Ford 4.0L SOHC engines put into production.

I have a 97 Sable 3.0L. The check engine light came on, giving me the code posted in this thread. I went to the local parts store & ordered the sensor. When I got to the sensor in the car it was different. The senor on the left, is the one I bought. The sensor on the right, is the one I have in the car. After all the trouble of locating it & getting access to it, I find out it's the wrong one. Now I need a special tool to replace it. This sucks... I thought this was going to be easy.

You don't need any special tools to change the CMP sensor on your 3.0L OHV Sable; the positioning tool is only required when changing out the CMP synchronizer shaft. Check out: https://www.ford-trucks.com/forums/2...placement.html
