Talking cam shaft position sensor

WOW.. I wish I had known about this blog before!!!!

I have a problem with my 96 f250 rough running.. hard start and just recently started missing at highway speed producing a buck, so to speak, then keeps going like nothing happened. I had the cam shaft position sensor replaced and it worked miracles. Now, 3 days later, it has started again this time stalling and not starting up right away.

I saw on another site something about the other components of this circuit and to have all pieces checked. Where is this part located??? Is this something that someone can do without removing multiple parts?

Any help will be greatly appreciated. This truck is my baby I hate being without it. Specially with winter weather starting

Welcome to

Double-check your connection at the CPS. Also, check if you're setting any codes. Most shops will check it for free. Once you check for codes, you'll have a better idea of what's going on.

If you were asking where the CPS is, i'm pretty sure its at the 10 o'clock position on the front of the block.

Welome to FTE As you alread found out, this is the best place to get
your rig up and running...lots of good/helpful people here.

If the CPS fixed it for 3 days then I would say you need another new one. It's not unusual
to have a new part fail that quickly. Even if that doesn't fix it you'll have a spare to keep
in the glove box. A CPS can totally fail without warning....leaving you stranded.

x2 what Cuda-Jim said about the CPS failure, also foxracing is correct on the location being the 10 oclock position on front of engine. You should always keep a spare CPS in the truck as well as a 10mm socket and ratchet, short extension and pliers,screwdriver so you can change it on the road. Likewise a spare fuel filter.

The cam sensor can be reached from under your truck, on the passenger side. To find out if it is the sensor acting up, look at the tach while trying to start it. The tach should move some while cranking. If it doesn't than it is quite likely the sensor, or a bad connection going to the sensor. If the tach moves, then the problem is likely somewhere else, but don't rule out the CPS.

Welcome to FTE.

I would beg to differ with the location however, it is more like the 1900 position.

Funny..... where you located I might need a shearer .

I sure do appreciate all the help on this and I will definetly have a spare right along with the fuel filter!!! I just hope it is easier for me to change then that cover on that filter.

The reason I asked about the location is because there is a group of wires that come out from under the cover on the fuel filter that are showing some wear and tear I was concerned that they might possibly be a contributing factor in why that went bad in such a short time.

Before I had the codes checked I had a concern that it was possibly the wire harness for the glowplugs/injectors as I had run into a problem with one of the plugs failing b4. I was checking that out and found this group of wires that go from the cover to the pasenger side firewall and possibly the selinoid(sp????)

Thanks again for all your feedback..

Paula

Paula,

I would check the connections at the valve covers since yo have gone through this before......there are 2 on each side....look for burnt pins and wires.....you can even smell them(rotten eggs= burnt harness) to diagnose.

Tayln(Bill) is in Mi down the road from me.....but I know he travels to shear.

The CPS is a 10 min. job to change and can be bought cheap now($25-30.)

I'm going to indiana on the 22nd of december (this month)
I'll be in virginia, washington dc, and west virginia on trips this year as well.

If there are enough sheep in your area for both of us to sheer for a week, we will make a trip if the jobs can be lined up.

I'd PM you this stuff, but you dont have enough posts for PM's yet.
