I'll have to do compatibility research, but we also have a '99 Explorer w/ 4.0 SOHC. Probably would be a different part though. There is the neighbor's truck. He's a **** anyway.
I talked to a local garage that knows the troubled history of this truck. He said that the sensor itself would not be bad unless the computer started throwing out codes. um, yeah. There has NEVER been a sensor that was getting weak that would give false readings in other words.
