check engine light came on for no reason

geebra · 10-06-2009, 12:08 AM

my check engine light suddenly just came on, i took it to the dealer they "fix" it but later it came on again..........what could be wrong with it?..........pretty sure its not the gas cap.....

What did the dealer fix? We can't guess, you need to give us more info.

geebra · 10-06-2009, 01:36 AM

he didnt even give me details.......i had their shuttle service pick me up, and by the time i got there, all the service ppl left.......and said my car was done......i guess im going back there tom

The manual states that either the gas cap situation or something w/the emissions sensor (or something rather) if activated while driving. Mine just came on yesterday too...wtf? I have a R/T cat, but never had the light go on for nearly 10k miles?!?! You have any mods?

im bone stock.......it was weird, i parked the car for 8 hours, cranked it and the check emissions system came up.........and i filled in gas like 4 days ago......then went to the dealer and they said they "fixed" it, but the light came back on

im willing to bet its a bad o2 sensor.

geebra · 10-06-2009, 04:25 PM

i hope they would fix it rather than just resetting......

Adule · 10-06-2009, 04:26 PM

You know what, the manual also states that it may take up to 3 days if the problem is neutralized, for the light to deactivate. Mine just deactivated after approximately 2 1/2 days of driving...so I'm happy (lets hope it was nothing serious). I say give it 3 days to see if the light will deactivate and if not, I'm also leaning towards a bad o2 sensor as stated by endless.

funny though, the acura techs never told me that it will take 3 days to neutralize

Your owner's manual does.

ya i know, so ill give that a try b4 i go in.........all asked me was, have you filled in gas lately.

would putting in a lower octane gas could have caused this?

speedlimitz · 10-06-2009, 07:02 PM

If they fixed the problem and erased the code it should turn off and not come back on. The 3 day sounds like the drive cycle but that shouldn't be the case in your situation. I'd take it back. Your reciept doesn't say what they fixed? Or did they even give you one

geebra · 10-06-2009, 08:47 PM

didnt get a reciept or anthing, still under warranty

Phisigbrotha · 10-06-2009, 10:03 PM

They should still produce paperwork for any warranty work. Im sure they have a copy. They need paperwork to submit so they get paid from Acura.

Plus its good to have paperwork on warranty claims in case this is a reoccurring issue even after warranty is up.

geebra · 10-07-2009, 11:34 AM

hmmm you guys were right, the check emissions system light went off...........should i still take it in to the dealership?

I did realize that the last time i filled up was at a full serve.....so im pretty sure the attendent didnt do the 3 clicks.....
