Having some grief with the above, TPS sensor seems fine, even tried another one thinking it might have a fault with lower readings but as soon as ignition is switched on it logs fault p0121 ans won't clear unless throttle is off idle.

Good supply to sensor and signal out consistent with live data, position on scan tool is showing idle as closed throttle and anything above as part throttle.

There does not seem a function to reset KAM to relearn idle position like on the earlier ones thinking it may be a software issue ?

Known lower stop is 0.68v and at idle we are close to that every time.

Searched archives and can't see anything similar , anyone had anything similar, I'm thinking maybe software issues ??
