Got sensor code P0101 MAF performance error on my xkr. Brought the car back to the dealer (non Jaguar). Checked all pipes and air boxes, all ok. Fitted 2 new maf sensors and new jaguar filters. Erased engine light code, but it comes back on after a short drive. We called several jag dealers to get information on sensors but all said "you have to bring in the car to them", One sensor shows higher readings than the other, which is the correct one the high or low readings? We drove the car with live diagnostics, steady at 90 km/h and left sensor (drivers side in US) is giving a lower voltage than the other.
Any one have info on the problem.
If anyone 07-09 xkr and has a diagnostics tool could they tell me what maf sensor reading they have when driving at 90 km/h, or when idling , what should each side be showing.

 

looks like nobody has any answers to my problem on maf readings, any views welcome

 

I am not able to tell you what is a correct value for your car, but since you know the sensor itself isn't the problem have you tried checking the voltages into and out of each with a multimeter?

You might also post the actual values you are seeing.

Some difference between the sides is to be expected but it shouldn't be more than a few milivolts unless there is some obstruction blocking airflow to one side or there is an electrical problem.
