Wire1 Brown blue wire goes into the Camshaft position sensor wire which is blue green (wire 3)

Wire3 on the tps is brown green and that goes into the ecu pin 53 as above and the other wire is the earth and it shares the earth on pin 30 see below

So that would say to me that the wire most likely to be dead is the brown/green, because it doesnt share this wire with any other sensor?

This gets more confusing than I thought...

by process of elimination yes it would say that, but do what the troubleshotting says and get a multimeter across the pins in the plug to check it, the wire going to the CPS could be off as iirc you had the loom custom made so could be a dodgy solder or similar,

I think its straight forward but i got the diagrams sat in front of me .

Fancy looking at the din data on the 1.0 corsa c and the astra gsi turbo as they share the same ecu but just use different pins lmao

Could be, will check that tomorrow after the purchase of a multimeter. Thanks Ben!
