Traction light and code P0101
 

I have a 2012 Sentra with a 2.0 engine and has 135,000 miles.
Having an issue with intermittent hesitation when accelerating but not always.
What happened first felt like a transmission issue because it jerk or buck but the car would idle ok. Then I noticed the traction light on.
I did diagnose test and got a P0101 code. The car has been running great until yesterday.
please help
