My car has 153000 miles.
My car has an automatic transmission.

Hi there. This is usually caused by a leak in the evaporative emissions system. This is commonly caused by a failing gas cap. I usually remove the gas cap and inspect its seal for cracks. If it looks bad at all, I replace the gas cap. If it is fine, then a smoke test needs to be done to see if there are any other leaks. If there are not any leaks, then it may have a bad vent valve. If you are planning on having this repaired, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose the Check Engine Light and make the necessary repairs.
