when you replace the sensor - what does the syncro look like?

rivguy,
the '96 2.3l has no snycro.its just a cross shaped sensor which reads a high spot on the auxillary shaft cam gear,or the oil pump gear as others refer to it.Thanks

I have the similar problem. I got the cam sensor code. i reset the computer and drove the car 20 miles and no light. I shut the vehicle off and resterted it and the check engine light came on. Truck runs fine. Any ideas? By the way; where is the cam sensor located on the 4.0 engine? hard to change?
