Hello Sir,Mam,
I have a 2005 Honda Accord v6 that has a code P2240-oxygen sensor open bank sensor 1.
I don't now what that means or were to look, The car has more than 1 oxygen sensor.
Will you please help me to find the oxygen sensor that need to be replace.?
The check engine light on, I thought it was the service reminder but it wasn't.
I don't have a book that shows the oxygen sensor.
Thank You for all your help.

I see the p2240 as a Bank 2, Sensor 1 code.....you kind of left out which "bank".

On the exhaust manifold, front of the car.

SIR, MAM,

 

Sir, Mam, I don't have any thing to add to this message,
I am sorry.

 

The sensor in question is in the exhaust manifold closest to the radiator. Can't remember but I think there is a cover over the top of the engine that has to come off.

There are tests that should be done to confirm it is the sensor. Yes they go bad and many people replace them when a code comes up. The choice is yours.

If you don't clear the code and the issue is corrected. At some point the CEL will go out, however the code will still be stored....but at least the light is off.

 

Thank You for helping me with this oxygen sensor .
I hope you have a great Thanksgiving.
Have a good day.
