If you really want to know what triggered the cel then you should run down to a local autozone they will plug into the diagnostic port(free) and tell you what is wrong, they will also try to sell you the parts so just say that you are going to take it to the dealer. In order to say what triggered the cel it would take more info.Certified Security Specialist

Always check info with a digital multimeter.

I promise to be good.

Tell Darwin I sent you.

I've been sick lately, sorry I won't be on much.

Thanks so much about the information on the check eng lite Thats right autozone does do free checks but want to sell you the parts.
