camshaft position sensor keeps burning out

[rucan]

I have a 1998 windstar and 6 weeks ago the engine light came on and I had the computer scanned and it showed the camshaft position sensor to be the problem. I replaced it and 5 days later light came back on again. I return the sensor for new one and sure enough it lasts a week and it doesnt work anymore I replaced it again and same problem after a feww days it stops working. what could be the problem??

you may have to be aligned
In this article, I am using a 1995-1998 3.8L Ford Windstar as an example. Usually the problem starts after engine work has been done. Maybe the timing cover has been removed or the engine was replaced. Either situation requires the synchronizer to be installed and timed to the engine. The service manual states that a "special tool" is required to index the vane inside the synchronizer to the housing. As you read through the procedure, you may be thinking, "I don't have that tool - now what?"

Good news! You can line up the synchronizer without a special tool and without a lot of extra time. Here's how:

1) Bring the engine up to top dead center (TDC) of the compression stroke for cylinder No. 1.
2) The engine needs to be positioned at 26 degrees after TDC. There will often be a large groove machined into the balancer at this point. If not, mark the balancer by measuring from TDC to 26 degrees before TDC. Take that measurement and make your own mark at 26 degrees after TDC.

3) Drop in the synchronizer so that the leading edge of the vane is close to the center of the opening in the housing (this is directly below the actual sensing part of the cam sensor).

4) Leaving the synchronizer loose, install the cam sensor and connect a voltmeter from the ground to the dark blue/orange wire with the sensor plugged in.

5) With the key on, the voltmeter should read either "0 volts" or "battery voltage."

6) Turn the synchronizer back and forth to find the point where the voltage is just switching from "0 volts" to "battery voltage."

7) Once you find that point, tighten down the hold-down bolt. This same procedure can be used on most OBD-II Ford products with Hall-effect type cam sensors.
