That does suck. That’s enough to drive you nuts. There are gears that change the trigger gear in relation to the cam though, I’ve used them before. TFS billet adjustable crank gears.

"If you look at the two different brand gears below, you see Lowndex's gear (2nd pic) moves the cam sensor with the angle of the cam (degreeing). The Comp Cams gears do not alter the relationship between the cam and crank signals, while still allowing the cams to be degreed. It looks like a small change in angle, but the Ford computer may see that as excessive timing chains stretch and call it an error condition."

Here are some clear photos. Waveform out of the cam sensor needs to be checked, although a solid signal won't prove that cam signal alignment is not a problem. Should confirm tooth/sensor function though.

Looks like it’s picking up on the adjuster bolts as well as the trigger
It also appears to be not be close enough to the outer portion for a good reading.
Although the sensors shown above prove to be all the same, what about placement on the cover for different 4V’s? If there is slight differences but close enough for stock gears, then I think you found the problem..

The placement of the sensor is the same
Looks close enough to me
I wonder if you put a washer under the sensor to put it just out of reach of the bolts to test if that's the case. You should still get enough when the big bump passes under the coil to send a signal. It's an easy test anyway.

Are the bolts stainless? If so, should be non magnetic depending on the grade used and unable to trigger the sensor.
Checking/ adjusting sensor height is a good idea. Seen a few bone stock vehicles which needed adjustment with replacement sensors.
The problem has been identified: picking up the adjuster bolt and gear tooth. The cam gear is from MMR and to their site shows a slightly different mount for the sensor. KC feels he has a simply solution and should be resolved quickly.
