bad bank connection or just bad o2 sensors

[karlsbad]

I have a 2005 range rover throwing codes - Bank 1, Sensor 1 - P2A00, Bank 1, Sensor 2 - P0139, P0140, P0141.... are my o2 sensors on that bank bad or is it possible there is a problem with the bank connections? Any thoughts.

Thanks

More than likely the Mass Air Flow Sensor is dirty or you have the air filter lid not on tight.

Was it a bad MAF ? I’m having a similar issue
