1998 Mercury Sable This Daughters Car Had Computer Hooked Camshaft Sensor Will

First you have to tell us which engine we're working on. Size and single or dual camshafts. They are different. Next, you must understand that fault codes never say to replace parts. They only indicate the circuit or system that needs further diagnosis. In this case it more likely than the typical 50 percent chance the sensor itself is the cause of the problem. Camshaft position sensors and crankshaft position sensors commonly fail by becoming heat-sensitive, and they will work again once they cool down. Your cam sensor isn't very expensive; still, you should check the wiring first to be sure no terminals in the connectors are spread or corroded and no wires are cut.
