I already received a new oxygen sensor and update yet my engine light came on yesterday. Anyone experience this or have any ideas? Car is driving normal.

 

Take the car to most any car parts store and they can tell you what code was thrown. (Usually for free)

 

I too received the amber color engine light the last time I drove. Manual says it's something to do with either the engine or transmission emission system bot no change in operation. I'm going to a dealer for something else so will have it checked at that time.
