Hi, I have a 98 4.0 0hv (my BF's). He took out the engine and put in an engine out of a 98 mazda B2000. It is a 4.0 ohv also. Everything was fine until camshaft synchronizer did not match. So he looked up the number on the part and it is for a 99. My question is can he swap these 2 engines and if so how does he make that part work? He is getting a p0340 code.

 

Ford/Mazda switched all 4.0ls to VR Cam sensors in 1999, its 2 wire
1998 and older used Hall Effect Cam sensors, 3 wire

The computer software is different for VR and hall effect sensors so you have to use the sensor the Computer is programmed for, its NOT a wiring thing, so no working around by messing with the wires, the signal from the sensors is different

The cam sensor and it's synchro tower of any years fits any year 4.0l OHV, 1990-2000
So you can swap over the 1999 cam sensor/synchro to the 1998 engine, or get a new 1999 cam sensor/synchro

 

Hello and thanks for taking the time to help! So the engine he has put into his truck is a 99 4.0 can the cam sensor/synchro from the 98 that he took out of the truck be used in the 99 that he put in the truck? I am just trying to clarify.
thanks

 

Yes, it can, pull out the whole synchro unit from the '98 and put it in the '99,it does need to be timed

 

Thank you so much!
