  Can you drive a car with the Check Engine light on?
  
  You will be able to drive your car If the car’s check engine light is still or solid, your only limitation is when the car is not running smoothly while the engine light is on. In this case, you have to stop driving it. If it is flashing the even, try moving it all else this might lead to major costly problems that will cost you’re a lot of money.
  
  You will find most likely to have a very pricy engine fix (e.g., the catalytic converter can cost ~$500 to $1,000, some cars have four of them). The mass airflow sensor is responsible for controlling how much fuel should be added to the air/fuel mixture.
