2008 Xc70 - P0175 System rich bank 2
 

This is a t6 petrol engine, I have being battling this fault code in other to get the check light off but yet still, I change maf sensor, checked for intake air leakage, checked injectors for leakage ; to the extend of swapping the 4,5,6 injectors to 123 yet still the problem keep showing in bank 2, this car has no turbo. Fuel pressure is okay on the scan tool as well. Please what else can I look into.

I'm slightly confused by the concept of a T6 that doesn't have a turbo?

this is a short video showing the reading of the oxygen sensors,

taking a look at first line sensor, and third line, you will see that the third line sensor is not reading to match or meet the first sensor, on top... and the third sensor is the bank 2 sensor 1,

and the top first line is the bank 1 sensor 1...

There is a 3.2 straight six non turbo model in the range somewhere.

Indeed there is.

But it's not a T6.

It's badged 3.2.

St4 and i-s , grateful for the correction yes it is 3.2 and I name it t6 because I saw that it has 6 cylinder.

By the way no answer to my question
