My 2007 Saturn Ion has a Check engine light, as far as I could hear, it sounded it really good still, and the oil is still full, the gas cap was closed and everything. I’ve heard that the Oxygen Sensor is a common issue, it seems minor as far as I can tell, so I’d appreciate some input on my check engine light, like I said, engine sounds great, gas cap is closed, plenty of clean oil, and nothing coming from the exhaust or a weird color.

(btw it has 75k Miles and has been well taken care of but still used,!which should say something)

 

Go to AutoZone or similar and have them read the codes from the diagnostic port.
It's free.

Get a list of the codes and post them here using the format Pxxxx where xxxx is a 4-digit number.

 

Got it scanned, said P0446, it said it was the EVAP. Still gonna get it fixed of course because I’m not trying to ruin the car, even if it might not entirely “cause” anything terrible, it’s cheap.

 

If you don't have emissions testing let it go. It's not hurting your car at all.

 

Luckily, my county in (Ohio) doesn’t do that

 

Should you ever have issues where it becomes difficult to put gas in the tank, where the pump keeps clicking off immediately, you may need to address this. Otherwise, per Gary, it does no harm.

 

... it does no harm
BUT, now that you are used to driving around ignoring the MIL
What if another more serious code were to report?
You'd not have a clue until after the damage had been done or until you are awaiting the roadside hooker from the auto club.

So what that is, the EPA determined that gasoline evaporating from everyone's antique fuel tanks was ruining the planet. So they MANDATED that all new automobiles after a certain date must have a sealed fuel system and that the integrity of the ''sealed system" must self test and alert the driver by illuminating the ''' Money Light "'

What I propose is that once it is on, several others could stack behind it, some maybe potentially serious, and granny will never know because her know it all grandson told her to "Just ignore it, trust me"

 

What if another more serious code were to report?
You'd not have a clue until after the damage had been done or until you are awaiting the roadside hooker from the auto club.

The clue might be that the engine is not up to snuff. That light will not save his engine. If there's that kind of damage it will show up in performance.

 

However, I’ve got a few questions…

-How Difficult is it to fix?
-How Expensive
-What do I need to fix?
