Rich the check engine light is not necessarily cause for immediate action. My 2013 car threw up this warning, the dealer tried various fixes swapping out various bits on the engine. I collected it with light out & set of home but the light came on again within 20 miles. I drove it for around 2 months with warning on till they could look at it again. A new updated ECU solved it. I did not notice any detrimental effect with the warning on either performance of fuel consumption. Its a yellow light not red so not to panic.
