Ok.just bought this car weds from a dealer.not honda/acura dealer
Not sure if it was throwing it when purhased or if it came on after..but on Saturday.
The car threw the gas cap light and this p0171 code showed up.I imagine its 2 different
Things because gas cap light went off.but on the messages it says the code
Still.
I been searching and some say vaccum leak some say 02 sensor by cat..
The car has hit around 44k.
And I noticed upon start.it will take probly 4 or 5 turns for iit to start.
Like its hesitant some.
Could it be somthing more than just a 02 sensor?
Should I just order me a 02 sensor and replace?
Has anyone had this code and it end up being 02 sensor?

 

I know when the car kicks a code the message will stay in messages until it is cleared out.
I do not know how to clear it because the dealer has always done it.

 

Sounds like there could be a bunch of things to try after reading some of these posts...

Ya.I got mixed answers...that why I was kinda seeing if anyone one has had this issue
And fixed it by doing certain thing..
Ima try and talk to they dealership and see if they can check it out...sux that..what...3 or 4
Days later cel comes on..probly was on when I bougt it because I didn't even know the car
Stored it and gave alerts.
Kinda makes me feel like I probly bought a lemon

 

Ok..searched up...guess I don't have a cel?its stored in navi or watever..
I think I found out how to clear the code,but unsure because it says I have to
Reactivate acuralink..
Guess that's why the dealer saiid I have to go to acura dealer to clear it because they
Didn't have equipment.
Has anyone reactivated acuralink?from what it looks I have to go online o customer service.

 

disconnecting battery doesn't clear it?

 

No codes here, but my TLS doesn't start quickly either, but I believe that is normal for the Honda v6.

 

It is the emmission evap purge control valve. Alot of good info on how to fix this yourself for the price of the part on acurazine.com

Very common on the 04-08 TL

It is not the gas cap or any other common problems that you would think of. A well documented problem with a fairly easy fix.

 

Your TL will need a simple PCM update. Applies To: 2007–08 TL Type–S – ALL
