cam sensor on 1994 Ford Escort

to replace it do you have to pull the heads

Asked by for the 1994 Ford Escort
No its at the driver's side rear of the cylinder head, dark green and a light blue wire attached to it I think. A little over an hour to change.
I finally found my cam sensor and I detached the wires and sprayed with electrical contact cleaner as well as the gizmo that it's attached to above it that was loose and I tightened it. I'm not sorry I bought the oxygen sensor, worth 140,000 miles, because it got me a new code number, from 412 to 214 at Pep Boys (free code check). I also sprayed the MAFS real good, and anything else I could find. Drove the car 12 miles and no more Check Engine light for now. I'll keep my 1994 Escort LX a couple of years more now that I have a new headliner, detailed inside and out, 2 new tires etc.
