if check tire pressure light still on after filling all the air, is it mean i might have issue with sensor or tires?? almost died today because of flat tire on the highway,,,

 

my guess would be a nail in your tire.

 

If you had a bad sensor, i think it would say TPMS not detected. I had 1 sensor that failed once and it had a different message ( not 'low tire" that i think you are seeing). I went to Discount Tire and they had a hadheld unit that re-synced it.

 

If the car can't find one of the TPMS sensors due to it being defective, dead battery, or not registered to the car the message will be "CHECK SYSTEM" with the TPMS light on the dash lit and a flashing exclamation mark.

 

Sometimes you have to go above the recommended pressure by a few pounds to get the sensor to reset. Once it resets you can let the pressure back down to the recommended level.

 

took the tire off today and saw the big bubble on my tire,,,dont know if tire is bad or what,,,did some research on my pirelli but didnt find anything,,,

 

Time for a new tire. Here is an article about it.
