Car Forum / Honda Cars / August 2006How many o2 sensors on 1996 accord?
I need to replace one and I was told bank 1 sensor 2. Are there more than 2 sensors on the 4cylinder? I see the one on the front of the engine where is the other? Thanks:) :) wrote: > I need to replace one and I was told bank 1 sensor 2. Are there more > than 2 sensors on the 4cylinder? I see the one on the front of the > engine where is the other? Thanks:) There should be one before the catalytic converter and one after. Sensor 2 would normally be the one after the cat. John >I need to replace one and I was told bank 1 sensor 2.

Thanks:) The "bank 1" part doesn't apply to single manifold engines like yours; on engines that have dual heads and dual exhaust manifolds one side is bank 2. In each case, sensor 1 is the one ahead of the catalytic converter that provides feedback to the ECU to correct the mixture. Sensor 2 is after the catalytic converter to monitor the catalyst operation. With that bad, the ECU doesn't know if your emissions are in spec or not.

Thanks:) ------------------------------- Actually, you need to tell us the CODE that helped 'them' come up with that suggestion. It should be written down on your work order. All is speculation otherwise. What symptoms do you have? 'Curly' > ":)" wrote: >> I need to replace one and I was told bank 1 sensor 2.

Thanks again to all of you!!! :)Nel > > ":)" wrote: > >> I need to replace one and I was told bank 1 sensor 2.

I only glanced at the list. All is speculation without the CODE, whether he got it for free, or paid somebody to read it.  Signature'Curly' |
