Problem with Lambda sensors

so scanned the car as it seems to be using fuel like crazy and was surprised to see all these codes related to both lambda sensors, surely they both cant fail electrically? I've checked fuses on the interior fuse board etc and all seems okay? Anyone had anything like this before?

I don't think the fault codes are that efficient to always accurately label them as "implausible signal" or "open circuit" etc.
Any wiring break can cause it to get confused.

I think you'll just have to get it up on ramp and look at the cables from the sensors.

Still getting the codes however it had an emissions test yesterday and passed the lambda test, but found that it had an exhaust leak just before the turbo so think it might be that
