Question about 2005 Chevrolet Express
I assume that you had the code pulled from the computer,and it sounds like it is an oxygen sensor code.bank 2 is the passenger side oxygen sensor but it should have also said sensor 1 or 2.sensor 1 is the first 02(oxygen sensor) you see looking from the manifold along the exhaust towards the rear of car and the 2nd 02 is the second sensor you see along the exhaust.past the front Y pipe.this all i can help with the info you have supplied.
