Answer
Jhun: Good Afternoon to you! The check engine light, would be that the computer in your car is picking up a problem in the system. You need to take your car someplace and have it coded. That is where they took your car's computer up to their computer and it will read out any problem that is being picked up in the system. It could be a weak
sensor(s) or the computer could be having a problem. Hope this helps and good luck! Linda :o)
