Per the sticky up top I went to Auto Zone to get the code for my CEL. I got back P1456 and the sticky says its this: P1456 EVAP Emission Control System Leak Detected (Fuel Tank System).

I have no performance mods done to the car and I just hit 30500 miles on the odometer.

Since I read the code I also cleared it. This took the CEL away and it has not returned since.

Should I be concerned about any of this?

Thanks guys!

Fuel cap can cause this. Make sure it's on 3 clicks and you should be fine.

i had the same thing about 2 months ago....its fine....just makes sure you dont over fill you gas and make sure your gas caps "clicks" 3+ times....and cel went away after about 1-2 weeks....

I wish every member who posted about a CEL was as thorough and self-serving as you.

And yeah, if you didn't screw the gas cap on tight enough, you can get this code.

 

You guys were right... Gas cap was not on tight. Thanks for everyones help!

just one other thing about the gas cap...on my 2003, i have to go past the point where it first starts clicking. like, it'll get semi-tight (and start clicking), then loose, then tight again for good. i found this out when i got the same code last year.

 

This site is great. I got the CEL driving to work (at speed)................ was in the back of my mind all day until I got home and checked it. P1456 - Fuel tank temp sensor ckt......... Cleared it and monitored/logged data for one driving cycle - nothing showing up yet.

First thing I do is a quick search on P1456 and see all the comments here about fuel cap not tightened. I'm thinkin' 'I *always* make sure I hear at least 3 clicks from that thing', plus I already went through a quarter tank, so why wouldn't it have shown up sooner?

Walked back into the garage and son of a b*tch if that cap was not tightened properly.

You guys probably saved me hours on the Web researching P1456. Worth my membership fee in and by itself.

THANKS!

WOW....I just picked up my S a few days ago. I was driving downtown a few mins ago and my CEL light came on. I got that oh my gosh sick feeling in my stomach. Went to Autozone they checked it and its the P1456. My gas cap clicked the last time I filled up, but felt like it was kinda cross threaded or something. Just took it off and put it back on. How do you clear the CEL?

 

Directions to clear a CEL in the FAQ... sticky.

I just got this code today driving to work. If it wasn't for the site I would have never thought to check the gas cap I s2ki
