Got this checked with a Fiat mech, and he says nothing to worry as there is no problem with acceleration or there is no missing. The car runs just fine.
My worry is will this bring up any issues later? |
I would think it is a simple question of the CEL bulb blown. Now, that might sound simple, but on some cars, replacing the bulbs and or LEDs in the Dash is a real royal PITA!
In itself its not an issue at all, but if there are in the future issues the CEL light will not come up and you won't have a clue. Not all issues that light up the CEL require immediate attention, but you do want to know that something is amiss, so you can take an educated decision as to what to do. Leave it, get it fixed etc.
As yours isn't working you will never know until you hook up a scanner.
