2007 Mazdaspeed 6, only been 1month and 8 days
2012 miles

Got up off the bed, prepared for work, started the car, the usual warm up idle, then all of a sudden I noticed that the engine light stayed on.
Well with-in the warranty, no mods, just engine light is on. Checked fuel cap, it was on correctly nice and closed. Sounded exactly the same on idle. Last drive, drive around the city, didn't stall or anything.

Any suggestions?

i'll bet cash-money that it's the EVAP code. i.e., leak of gas vapors. the dealer will most likely tell you that you failed to full seat the gas cap. i assure you i full seat the gas cap with every fill up.

i've had this problem 4 times now. the first time the dealer gave me that lame explanation, the second time they replaced the purge valve. times three and four i got the same lame excuse. i think i'm going to upgrade to an aftermarket gas cap.

What does "Full seat" mean? Is there any other way, method that I can do to make the light go away? Filling up my gas tank to full not over clicking it...it was cold this morning too about 39 degrees...would that be the cause?

First, go get the code pulled! Most major auto parts places will pull the codes out for free. Once you have your code(s), if the store didn't tell you, someone in here can lookup what the code means.

My guess it's going to be some kind of evap code.

Let us know what the code was.

I just had my front O2 sensor replaced, because of a code. I think the sensor got fouled up when the turbo went bad.

Agree with mk706. When I had the Engine Light on, I took it to the Autozone (lot closer than the dealer) and for free they checked it and cleared it. It ended up being the gas cap not being tight enough...

Just from a quick search on net.
P0455 OBD-II Trouble Code
Technical Description

Evaporative Emission Control System Leak Detected (no purge flow or large leak)
What does that mean?

This indicates a fuel vapor leak or lack of purge flow in the EVAP control system. It means a large leak has been detected. The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle's fuel system. Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine.
Symptoms

You likely won't notice any drivability problems.
Causes

A code p0455 most likely means one or more of the following has happened:

* A loose or improperly affixed gas cap
* A non-conforming gas cap (i.e. not factory/original brand)
* Other leak or damaged piece in EVAP system

Possible Solutions

With a p0455, the most common repair is to:

* Remove and reinstall the gas cap, clear the codes, and drive for a day and see if the codes come back.
* Otherwise, replace the gas cap, and/or
* Inspect the EVAP system for cuts/holes in tubes/hoses (you may hear a vacuum noise or smell fuel), repair if necessary


Hope it is accurate.
