Did test, did tuneup.


Replaced a lot of sensors.

Define "everything". What "test"? What is a tune-up? Define "a lot of sensors". What SPECIFIC DTCs did you get with the code reader? "tried everything" would need to include a scanner with LIVE data. What can we do to help?
I need to know what I NEED to do to get the engine light off so I CAN get the smog done. Thanks, Deborahhurst

Take it to a qualified mechanic for diagnosis and repair!!
