gas tank light on

[sgreer1964]

what is the fix for gas cap lid light on dash

 

[Bigskyroadglide]

Generally first start is to identify the code associated with the light. Advance, O'Reilly's or Auto Zone will do this code identification for free, then it's up to you to address. It could be

the gas cap
the evap canister or something else, without knowing the code

Everything is a guess.

I would recommend if its gas cap etc, use mopar parts, buy once cry once
