Check engine light warranty?

check engine light came on. Auto zone checked and it is code P2201. After treatment NOx sensorcircuit performance-Bank 1 Sensor 1. Dodge says I can use truck till I get it in for service in a couple weeks. Does anyone have experience with this? Also, purchased truck in Dec 2013 and it only has 30 k miles on it. Is this still under warranty?

There is supposedly a Federal Emissions warranty for 8 yrs/80K assuming your issue is covered under that. I can't see where you're located. But, in CA, there are additional emissions parts covered by a 7/70 warranty.

I have the same code. It falls under the 5 year 50k warranty. From what I have learned it trips the CEL because it is getting a funky reading sometimes it is actually the sensor (which is located in the elbow right behind the turbo) othertimes it could be the DEF injector nozzle is gummed up or possibly junky DEF. FYI there are two of the NOx sensors and they are not the same according to Chrysler the second or (lower) sensor is downstream of all the exhaust mumbo jumbo. If you have to buy the part it is $1300 at the dealer an aftermarket sensor can be found for $350 or so. I am choosing neither of those options. My truck has 82k on it its time for EFI live.

Hope this is helpful
