I will check this weekend and get back to you.
Also would you know how to check a o2 sensor manually?

Thanks for the reply

O2 sensor tests are hard to do and you ususally need special equipement, and the tests results are often inconclusive.

Hi blacktop, the code came in as p0175.
I understand this means a rich condition and it refers to bank 2. Can you tell me what side bank 2 is and if the sensor is before or after the cat.

Thanks for the help.

If its rich on bank 2 then it has to be sensor one which is before the catalytic convertor on the exhaust manifold, as the one after the convertor, sensor 2, is used for catalyst efficency.

Bank 2 is the side of the engine that doesnt include the #1 cylinder which on fords is the passanger side.

So your looking at the sensor on the DRIVERS side BEFORE the convertor.

Thanks for the reply, however I am a little confused.
In one paragraph you say that bank #2 is the passenger side, then the next paragraph you say it is the drivers side. Could you please let me know what side it acctually is.

Many thanks

Sorry about that I was saying the passanger side had the #1 cylinder so the one oppositve of that is the drivers side.

Your looking at the drivers side.
