Three Reasons Why Your Check Engine Light May Be On

Engine LightHas your check engine light gone off? There’s no need to get nervous. Check out this list of reasons why this light may be going off:

  • Gas Cap Not Secure – This is one of the most common reasons why a check engine light might go off. If you have left your gas cap loose or left it at the gas station, there are sensors that tell your car to set off the light. You can replace your cap, and it may go off, but you may also need to take your car to a specialist to turn off the light.
  • Tire Pressure Issues – If you are driving an older vehicle, your check engine light may go off when the tire pressure is too high or too low. Many modern cars have separate lights for tire pressure issues. Try filling up your tires correctly and see if that fixes the problem.
  • Oxygen Sensor Problems – When you drive, there is a certain amount of oxygen in the exhaust. If the fuel mixture has too much oxygen or not enough oxygen, there could be a problem. Your sensor will set off the check engine light, which tells a mechanic to check this problem.
