Can anyone shed some light on this strange fault?

I've got a recurring "impulse sensor fault" that come back pretty much immediately.

Up to now ive changed the crank ,Cam sensors. Changed the crank sensor connector ( as the wires had split insulation)

I've checked all the ecu connectors, cleaned them and checked for corrosion (non apparent)

Ive then checked the 3 wires from the ecu connector to the crank for continuity/high resistence, and everything checked out there.

The only then i can think thats left us the ecu itself.

The car runs and drive with no warning lights (just the impulse sensor faulty message when ypu scan for codes. The cars definitely down on power. It cant get past 60mph or rev pas 2500rpm. I suspect its stopping the vnt in the turbo from moving.

l've logged the rpm signal coming from the crank sensor and theres nothing wrong with it. Signal is constant with no dips or breaks in signal.

5v and sensor ground look to be good

The only thing that does look funny is theres 10v on the signal line. Im not sure if this is normal or not as I can't see the raw data for the crank signal line with my scanner.

Any help would be appreciated
