Default ford 2.3 crankshaft position sensor

hello, does anyone here have any experience with these? i know the wiring goes up under the timing cover for this, but where does it come out and plug into? is it hard to change? my engine is spitting and sputtering at almost all speeds now, and codes say it is this. any help appreciated.

try keeping it all in one thread. no need for 3 threads on one problem. Changing the sensor isn't the easiest thing. bout as hard as doing a timing belt, which you might as well do while you're in there. You'll need to take the timing belt cover and crank pulley off to get to the sensor. you'll see it's attached with 2 small bolts. some people insist on using the alignment tool when installing the new one. I personally didnt use one and haven't had troubles but that may be just luck.

Anyways if you dont have access to the tool you can use something like a buisness card or feeler guages when installing the new sensor to make sure it has an even gap on both sides. Once you start getting into it you'll understand what i mean. good luck.

it dosen't "plug in" on both ends. one end is the crank sensor the other end goes to the wiring harness. it dosen't come out either. it's bolted to the block behind the timing cover.

the other end of the wire is under the intake manifold, there's one single wire connector and a 4 wire connector that are in the same loom.

at first glance you would have to take the rear timing belt cover off to change the sensor assuming you get a sensor that isn't just a pigtail to splice in. you can put the new sensor in without taking the cover off if you pull the wires out of the 4 wire connector, push the wires under the cover then put them back in the connector. If you are lucky, the replacement sensor has the same wire colors in the same location as what your engine originally had. To pull the wires out of the connector, use some small pliers and pull out the red wedge from the connector then release the latches on the wire terminals with a needle tool.

ok, so since you guys have both changed them, what were the symptoms of them going bad on your trucks?

A bad CPS will throw the timing off. You might throw a code. You will have fuel and spark and it will not start

I changed mine b/c i had the engine apart on the bench- cheap insurance. so no symptoms. But i have had 2 cam sensors go bad, and the truck just bucks like crazy and dosen't run very well. I'd imagine the CPS would have about the same effect.

ok, now here is the next problem. i gave the codes that came up already for pip failure and cylinder id failure. now i find out that i also have a cam position sensor which i found under the intake. goes on with 2 screws. so how do i tell which sensor is bad and causing this problem? they both have to do with timing, correct?

we need details, details, details..........update your vehicle profile so it looks like mine..............GIVE US THE ACTUAL CODE #'S YOU GOT...............the camshaft positioning sensor is more of a fine tuning of the timing. I think the truck will run if you disconnect it.......they did not start adding them until 95, 94 in califonria
