F53 oxygen sensor

[Mike_M2]

I had my check engine light come on recently and after reading the code it seems I need to change an oxygen sensor out. Seems to me that at 23K miles it's a little premature for a failure. Has anybody had this same problem on this chassis?

that leak is realy not that evident its very small in my shop we use a smoke machine that when engine is off we put smoke in the intake manifold and look to see wear the smoke comes ouy

I'll check that out next time I am at the coach. Thanks for the lead! I did notice that as I did more searching on the internet, the O2 sensor was less of a possibility.

The engine was quite warm when the code popped up. Hopefully the leak point will be evident....

The reader we used showed the exact sensor giving the trouble but I don't remember which one. I believe it was a downstream sensor. I'll reread it tomarrow and let you all know.

That's funny. I just had the first code on our old F53 V10 and it was fuel mixture lean bank 2. I hear it might be O2 sensor as well.

What code did it set? There's quite few codes associated with the O2 sensors. Not all of them mean a sensor is bad.

I get an O2 sensor code periodically. Use my Scangauge to reset it and it's fine for months.

Pick up a 6 point O2 sensor socket... it has a cutout for the wire... makes life easier. And while you are waiting to get the new one(s) , spray the old ones with penetrating oil and let it soak in a few days, if possible.

MikeM2: Do you know which one it is? Most likely you have multiples. 4 or more.

It's been well over 10 years! OK, i'll order a new one and put it in next weekend. Thanks all!

Electronics. There ain't no tellin'. They fail quickly or last forever. However, the O2 sensor might come under the 5 year/ 50,000 mile air pollution warranty.

g'luck!

Have a friend and his came on in less than 2000 miles.

Dealer fixed under warranty.

If you give me year engine size and code I'll tell you how to check it very easy to do

How old is the RV? Most last 100,000 miles and are replaced at about 7 years old. I had to replace mine at about 45,000 miles when it was 15 years old on my 97 460" V8 Ford.

I do not consider it unreasonable. The part cost me only about $55, it is the same one used on the 1996 F-350 with the same engine.

I installed it myself, there is plenty of room under the RV to get to it.
