O2 sensors
Im sure the answer im going to get is if it aint broke don't bother with it but well see.
I have never replaced one of mine, and I have around 175k on them. Is that normal? Would there be any gains to replacing them? I really dont have and mpg complaints. I averaged 17.2 on a 200 mile trip running around 62mph for half the trip and 72 the other half.
Just throwing it out for discussion. I like to see lots of interesting conversation on our forum.
Thanks fellas

I replace them as a maintenance item, usually every 100K. They can get "tired" before they eventually throw a code to be replaced. Since the fronts tell the engine how to burn the fuel you want them to be as efficient as possible at all times.

A lot of vehicles that have front/back O2 sensors, the sensor that is located behind the cat. converter is used only to monitor the cat. converter function and will trigger a trouble code. This type has nothing to do with how well the engine runs and there is no economy/performance to gain by replacing it.
So before you plunk down your hard earned cash for a replacement, find out for sure the purpose of the rear sensor on your vehicle.

You CANNOT use a wide-band O2 sensor on your truck. It's a tuning tool only used with a processor that can see the wider range of air/fuel measured by the wide band sensor.
