My Emissions System indicator light came on this morning about 10 minutes into driving. I have a 2012 Civic that only has about 69,000 miles on it. Any possibility there is an easy fix for this or am I am looking at something that's going to cost an arm and a leg? The car is in good shape otherwise, obviously isn't driven for long distances, but I'm back in the office a couple of days a week now and am concerned about how quickly I need to get this fixed? Any help is appreciated!

Pull the fault codes. Parts stores will usually do this for free.

Need to scan the car, either parts store or buy a scanner for under $20
