Dav, Whilst you have a code from the sensor it doesnt mean the sensor is defective. The sensor is detecting an air to fuel ratio problem; it doesnt necessarily mean that sensor is defective. The cause of the air fuel ratio needs to be checked/verified first. You could be about to spend money on a component you dont need.

My other observation is that it is expected that all members should endeavour to do some 'self help'. You have a computer so why are you asking other members to do the leg work of shopping for this part you? As member GCMarcal has listed why didnt you look this up for yourself on your computer?

This Forum also has helpful posts as to where to obtain GM parts. The Forum Search function is an ideal tool for provided for this type of information.
Typically here :- Chevrolet Parts Mail Order.

Six months on and you have not embraced any understanding of this information.

teribil (Terrible) mpg and fault code keeps coming back after clearing code
Typical description example of possible poor air/fuel ratio. Have you checked air filter, have you checked or cleaned (carefully) the MAF sensor, have you checked the air intake hose for splits or tears (this can allow incorrect air fuel ratio).
Have you used the Forum Search Function for similar issues.

If any of this is beyond your scope take the vehicle to your nearest GM Agent.

Thank you so much for your reply. I've just fitted a second hand 02 sencer now and a new air filter and checked air filter box with map sensor and air filter pipes that fit onto turbo and I've checked fuel filters making sure they are seated correctly and change leak of pipes as i had 4 brand new injectors fitted and checked for leaks from injector pressure rail and changed pressure sensor rail senser and I've cleaned diesel fuel cap and i checked the fuse for the Lampard sensor bank 1 and the dpf regenerate properly now now I've spent well over a 1000 on this car after I Paid 6000 So I clear the fault code and the fault has come back next step is auto electricians as i am get a power signal for the Lampard sensor heater

Could it be the intercooler pipe leaking for code P2246 ????

Any leak or tear can affect air/fuel ratio. There is an outside chance that you may have a defective (burnt) throttle body gasket. (a b*gg*r to get at)
I'm assuming you mean Lambda sensor. With the items you say you've checked we are starting to run out of possibilities.
The work you've had done - has this been by a GM Agent/Dealer?
