F53 oxygen sensor

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.

Hi All.

Do you have any "SMOG" requirements where you live. A hose could have easily come lose. I have had that happen to me several times, but not a Sensor. Do you know anyone who has the same Motorhome as you do? What Motor do you have?. Doesn't really matter, a 454, a 460 or the V10, you can try one from a car also

If so, see if they will let you try out their sensor. That would only take you a few seconds to check it out. I've even seen many Motorhomes Fail do to their Gas Caps, of all things.

Good Luck. Happy TYravels, Dan & Jill & our two small "YORKIE KIDS' who love to travel as much as we do.
