Open circuit suggests there's a broken connection somewhere between the sensor element and the ECM.

Yes I agree,going to put a meter across it tomorow to check for continuity, if I get a loop, then i don’t know what I will do.hopefully the o/c is in the sensor ,if so do you know if the front prop has to come off to get access to it. Thanks anyway.

Yes it has got adblue, but wouldn’t that show up on the code reader.
