May be one of your O2 sensors went bad. Usually the one closest to the combustion chamber is the failed sensor.
If there is an AutoZone store near you, they will read the diagnostic code for free.
The Sentras were recently recalled with symptoms of engine light coming on. Reason: Crank sensor and lining in CPU box needs replaced.
