Code P0155 on my 02 Blazer
Hi, everyone.. This is my 2nd post here, new to the forum.. I have had my blazer now for 2 years now and just now the check engine light came on, so I checked it out.. The code P0155 " H02S Heater Performance Bank 2 Sensor 1" Is this my O2 sensor that went bad?

I believe bank two is the one for cylinders 2, 4, and 6. Sensor 1 would be the first one that is closest to the beginning of the exhaust manifold.
