You're good. Might run a little rich. I have been told Long term use might cause some issues with the catalytic converter. I ran a car for 50k with a bad o2 never threw a code for the cat.

I wouldn't trust any advice unless the person can see and smell the exhaust.

A 02 sensor can pop off for a number of reasons. Some minor and some ( stuck injector) are major.

How many miles on the car?
Some pop on the light at preset mileage as a reminder for standard factory defined maintenance.

I would think he would have read more codes if it was much more than a faulty sensor.

IMO I wouldn't be worried based off of info in OP, a solid check engine light with a single o2 code would not raise much concern if nothing else seemed off.

Thats me too but I don't know Cav vets abilities.
It's probably just a slow sensor but it might not be. Need more info

i can fuck something up as bad as the next guy.

i asked because i pondered running it this weekend on a little road trip, but Google got me scared of fucking up the cat converter.

stole it from the wife, drove right in the dealership. i bought the chrysler factory lifetime maxcare warranty when new, they just called - all done, all covered.

thx to everybody.

Have a nice trip.

What did they do?

O2 sensor problems almost always entail increased fuel consumption, and possible damage to cat convertor. You were wise to have it serviced under warranty.

Here's a tip: If you have not recently done so, replace your air filter before the trip. Your engine will breathe easier, and you will increase your fuel mileage.

thx raf, it got done before i came in.

they just said it was a software problem. they said per chrysler, if the fault comes back they will replace the catalytic converter. and my max care warranty covers it!

best $1800 i ever spent!
