My driver info center thing says "check fuel cap".... I've tightened it and put on another fuel cap on it and its still on.... Is there a way to clear this code or is it something else.

 

No, it just goes off on its own, I had the same problem even though I had the cap tightened all the way down. It took a few days for it to go off.

 

^yeah but it'll come back eventually. it's a known issue with our cars...there is a thread here somewhere exposing what part/sensor it is that needs to be replaced. try a google search with the word acurazine in it and it should be at the top of the list.

there are like 100 threads on this topic, I even think I made one a long time ago. should be a TSB but I don't think it is sadly.

 

^^^ was it the thread with the seal cracking ??? coz i have seen that sometime back....

OP, if you really wanna clear the code, reset the ECU by disconnecting your battery for 5-10 minutes....before you disconnect make sure you have your radio/navi codes handy

 

I have a 2005 TL with 80k miles on it and my "Check Fuel Cap" signal came on today. Im not a very techy guy and i dont want to go to the dealer. Wonder how much it will cost at a mom n pop type place to fix up.

 

^^^ at your S/N....i bet all desi's have been to that website LOL

well you dont need to take it to any shop....it will clear by itself (HOPE)....

you can do the following:
1> wipe the fuel area well (with the fuel cap closed)
2> make sure the cap is nice and tight
3> disconnect your battery for 5-10 minutes (hang onto your navi/radio codes)
4> connect your battery and start your car....

if the light doesnt come on your all good....if it does then its prolly a broken seal
