Which Oxygen Sensor is this?
Good Afternoon Folks!
My '05 EX has presented me with a weekend project. I get this code from the OBDII - P2237 Rear Air/Fuel Ratio (A/F) Sensor (Bank 1, Sensor 1) IP Line High Voltage. My take on this is that it is the OS on the rear cylinder bank exhaust manifold. The darn things are too expensive to just start replacing them until the light goes out. What do ya'll think?
