DTC 2274 02 Sensor stuck on lean bank 1 Sensor 3. Does anyone know what sensor is 3. Is that the one on the exhaust manifold
When using a scanner for live data, to check 02 Sensor's. If there are 3 how and I want a certain one I don't want to be checking the one behind the cat. Will the scanner know that?

O2 sensors are the ones after the cat converter
As they are wired differently to HO2S sensors ( before the cat converter) the ECM knows which sensor is doing the reporting
with a bank 1 reading you should have a v6 or v8 engine in nwhich there will be 4 sensors -- 2 HO2S ( before the cat converter ) and 2 O2 sensors after the cat converter
