Cam sensor in a SVT head on a zetec engine/ECU

On my build I installed an SVT head on a regular zetec, car started but the cam sensor interferes and didn't let the car stay on. The tuner turned off the sensor and the check engine light because it would stay lit. Trying to find a way to have the check engine light to know if a code shows up. I could delete the extra pegs on the SVT cam to make it read like a zetec cam but it's already in time and running, was wondering if there's any pin on the ECU to recreate the cam sensor reading? Thought about the tachometer (pin 48) Any thoughts?

If this helps I know your trying to avoid pulling the cam. The "Peg Ring" on the cam is lightly pressed on. I've swapped them between SVT and reg zetec. To be safe you can use some Loctite bearing mount 620 compound.

The regular isn't pressed on, it's cast in and unmovable.


Grind the unused pegs off the SVT ring. That's what I did. Works just fine.

*Thought I had a pic of it but can't find it.

Celebrated a bit early LOL Didn't want to take the cam out to grind, like I said in first post but it looks like the only way.

For the SVT, yes.
Standard zetec, no.


My regrind has a pin and a tac weld holding it in place (was moved due to being reground).

Thanks! Running stock SVT cams and head on a zx3, this will make it run with the cam sensor on without pulling the cam.

I'm sorry if I was wrong. It was 10 years ago but I still think the zetec ring was removable. I got some cams on the shelf I'll look them over, perhaps some batches were pressed on?

For my issue it was the solution, thanks again.
