Hi,

I have a Alfa GT with 2.0 JTS motor. Reading out is working fine. I'm only wondering what is meant with bank 1 and bank 2. Can you explain?

Does bank 1 stands for cilinder 1 (at the site of the passenger) and 4 and bank 2 for cilinder 2 and 3?

Thx,
Hans

Tengo entendido que esto se refiere es al sensor de o2 que va arriba (bank1) y el banco es el sensor de o2 que esta despues del catalizador

Unfortunately naming and positioning of sensors might be confusing, as OBD-II standard does not give exact mapping for the id and place of appropriate sensors. Please follow the discussion at appropriate theme at our forum O2 Sensor Names

Thanks!
