Could someone tell me what the p0137 obd code means on my 2006 sebring?? I know it meansoxygen sensor butwhat is theexact problem and why did it happen? How does it affect the proformance of the car. I notice that is doesn't have any hestitation now( I had a little at first)when first coming off a green light when the MIL light is on. Is that normal?

 

Had the same code. How do you find out what a code means on this forum?
My mech had another code reader his code told what air sensor was acting up.
Apparently there are at least 2 sets of air sensors with more.
He told me it was an air sensor on the second line (harder to reach).
car still running but he said when it goes the car will run rough then we will have to replace it.
Has to do with air/fuel mix.
Don't know how they go bad but dirt is always a suspect problem.
My check engine light goes on & off about it now.

 

If you want to know about that code, just google P0137 and see what comes up. There are lots of sites on the web that discuss OBD codes.

You didn't state which engine you have in your car, but if it's a V-6, then there are two sets of two oxygen sensors. They operate in the exhaust stream before and after the catalytic converters. It's a harsh environment and failures are not at all uncommon. They measure the oxygen content before and after the exhaust gasses pass through the cats and thus are able to determine if the cats are working properly.
Since they work in pairs, it's best to replace them in pairs. Don't wait until the car starts running rough or you might wind up having to replace the catalytic converter as well, which runs into bigger money.

 

Thanks for all of the good info.
@ sensors you say to replace in pairs thx I don't want an expensive cat bill as well!
