It wouldn't even turn on and the man didn't say much but that it might be an electrical problem. I even swapped with another one to make sure it wasn't there machine

Ok. When you say the lights seem dim...do you notice them randomly become dim or flicker?
Customer

Yeah and sometime it seems brighter than other times.

Thank you for that information. Give me a few minutes to check my Honda site to see if there are any known issues, recalls, etc.

You possibly have two issues going on here. The dim/bright lights could be an issue with the alternator. This will not set the check engine light. The check engine light is on due to a [transmission](/topics-transmission-honda/) issue. The Auto Zone or Advanced Auto scanners do not read transmission codes. You would need to go to a Honda dealer or a quality repair shop that has a scan tool which can scan the transmission.

Honestly, it is hard to say. Without knowing the codes, I can't tell you exactly what the issue or the cost but my guess from years of experience is $800-$900.

Ok so I should take it to a mechanic soon right to have them check the engine lightWhat alternator is the best for my car?
Anthony P.

Yes, I would. If the check engine light starts flashing, don't drive it as that is a more serious issue.

A Honda alternator is best.
