Hello

replaced my battery 2 years ago for $150 at local Ford dealer, this morning it was totally dead. Got her jumped and drove to dealer to get it replaced, after replacing I have a CEL.. any ideas, running fine, will this go away? Can replacing a battery cause a code?

 

Take it back to the dealer.

 

I put the battery in, not the dealer.. do you think the battery is faulty?

 

Get the code(s) that the computer put out and go from there. If you don't have a code reader, most of the auto parts stores will read the codes for you for free. Be sure to ask them to NOT clear the codes because if you need to take it some place to get whatever is wrong fixed, that place is going to want to see the codes as well.

 

Impossible to say. Follow the directions given by Blue2016XL so you know why the light is on. Anything else is just guessing.

 

As above.


Having a code means nothing if you don't know what the code is.
