Sorry to trouble you, but I am confused over which sensor I need replacing.
I am getting P0037
HO2S Heater Control Circuit Low (Bank 1 Sensor 2).
on my newage WRX 2005 Blobeye. all 3 CATS have been removed.
not sure if its the front or rear sensor, and can also do with how many wires this sensor has and what the colours are ?any advise welcome.
