Bought a 'new' sensor off eBay from surplus stock installed on intakes but never actually used before GT production stopped. Installed it yesterday, drove about 150 miles today (with a few redlines in there for good measure) and I'm happy to report that the CEL did not come back. Thanks all for your input.
Rowing through the gears....purely for testing purposes. No fun was had on this drive
