Replaced cam/crank position sensor with no change in rough running engine. Syncronizer has not been replaced. Do I need a tool to syncronize both sensors? It's not been rebuilt or jumped time.

ignition coil?

When you ask for help with servicing your vehicle, it would be nice if you would mention WHICH ENGINE your 2002 Taurus is equipped with. However, in this case it makes no difference because niether of the engines available for that year have any adjustable timing other than the cam sensor syncronizer. Adjusting the cam sensor syncronizer requires the use of special service tools.

It is one of two things. Crank shaft sensor, on timing cover, behind crank pulley. Or the camshaft syncronizer, or the camshaft sensor (sits on top of Camshaft syncronizer) Located on drivers side end of engine, in what used to be the home of the old type distributor.

Hi, welcome to FixYa.com my name is Shawn and I will be answering your question.

It is not the cam sensor it is the cam syncronizer that needs to be replaced. That is the piece driven by the cam shaft that the cam sensor sits on.

I hope my assistance helped you and resolved your concern, if you need further assistance please ask.

YES. Very common problem. The cam sensor driver unit goes bad. (Usually called a "Cam Syncronizer") Squeeks like crazy, causes hard starts, poor fuel mileage, usually destroys the cam sensor itself, and will cause catalytic converter damage if not fixed promptly. (You will find broken, rusted pieces inside the assembly if you take the sensor off of the top)
Complete kits (Made by Dorman) are available at most parts retailers. It will look similar to this:

It should be noted that although this part is relatively easy to replace, it can also be very easy to install it incorrectly. Proper alignment (Syncronization) should be checked using a scan tool after installation.

The camshaft position sensor and syncro are located on the back of the engine and will sqeek. The syncronizer sits in the engine and is run by the camshaft. the camshaft position sensor sits on top of the syncro and is held down by 2 7/32" screws. If you remove the camshaft position sensor from the top of the syncro and put about 3-5 drops of motor oil in the syncro you may fix your squeek. The syncronizer shaft that goes into the engine will dry out and loose its lubrication causing a squeek/chirp.
I have done this to a few vehicles and had great success.
Hope this helps

You need a special tool to install the bottom (aluminum) part aka syncronizer. You have to have the engine on top dead center and with the tool install the syncro assembly. The tool will come with instructions.

Please get a brand new sensor.

New parts are better than used/ old parts.

Good luck and remember to rate.

look under the coil pack you will find a round black housing just about where the distributor used to be before they changed over to the coil pack engine

2 screws and this housing comes off and it is the cam sensor

a word of warning the main cause of cam sensor problems is that the magnet in the rotating part
(or as ford calls it the syncronizer ) this magnet comes apart and actually hits the sensor and damages it
if this occurs you have to replace the sensor and the syncronizer this requires a special tool to set
it ( if you do not use the tool you will set a code for cam crank not syncronized

Hope this helps David
