it means that there is too much oxygen in bank 1 of the exhaust. Bank 1 is the back of the engine on a front wheel drive vehicle, it is the passenger side on a rear wheel drive vehicle. you can search for a leak by spraying down the intake manifold with carburetor cleaner while the engine is running. when the idle changes or the engine runs rough, you found your leak.
Would it be Bank 1 if the car is AWD?
Bank 1 is the same side cylinder 1 is on the engine.
Where do the accessories mount on the front of the engine or the side?
I will look and get back to you. Thank you for the help!
I have same code and its making my 2004 t5 2.5L turbo s40 Volvo cut out at anything under 4k rmps. Iv changed fuel pressure sensor, MAF sensor, and O2 sensors. My question is: with this forced air combustion system (turbo) can I still check it with the carburetor cleaner as mentioned above?
