Question

How many miles should an O2 sensor last? My car has 5000 miles and is having problems? Will warranty cover?

Answer 1

For as i know there's really no exact number of mile's before one goes bad, but i know for sure it should not be bad with just 5000. mile's on it.Maybe if it had at less 30to40,000 mile's on it one could say that it should be bad, but not at 5000, mile's. Your check engine light should be on if one of the 02 sensors are bad.Your car should also be missing out are something like that.I would must definitely thank that the warranty should cover this.

Answer 2

I've always purchased an extended auto warranty for every car I've owned in the last 7 years.  I used to get them from the dealer, but lately it's less expensive to get them from an aftermarket company that specializes in warranties. http://www.autoadviceonline.com/Warranty... They offer free quotes, so it can't hurt to see how much one would cost for your car.

Answer 3

It's hard to answer any of your questions without knowing year, make, and model of your vehicle, but....O2 sensors have a general efficient lifespan of about 100k miles.  Every veh manufacturer I know will cover an O2 sensor with a manufacturing defect at 5000 miles.  How do you know you have an O2 sensor problem?

Answer 4

If your car only has 5000 miles on it then yes it will be covered

Answer 5

What sort of problems? Did you retrieve Diagnostic codes? If you did, what did the codes identify? Just because you have a code that identifies an oxygen sensor circuit or data doesn't indicate that the sensor has failed. It may well be doing the job it was designed to do.

For instance, if the code you retrieved was a P0171 (System too lean, Bank 1), there may well be an oxygen sensor failure. BUT the problem is more likely another cause, such as a restricted fuel filter, a failing fuel pump, a MAF/MAP sensor slightly out of calibration, a coolant temperature sensor outside spec, a fuel injector restriction, or a vacuum leak at a hose or intake manifold or throttle body, or the power brake booster may be failing.

Proper and satisfactory repairs come after proper diagnostic routines, NOT as a result of throwing parts (and money) at the problem.
