You’ll need to have someone with a code reader pull the stored codes from the computer for us. They will be in the form “Pxxxx”. If it’s more convenient, you can buy a code reader for about $20.00.

I can think of any number of components which could fail to operate properly, yet generate a code which commands the mil on, yet doesn’t seem to affect drivability
