We forgot to close the gas tank in the inside and same day my engine light came on. I close the cap and same day i took it for a drive and the engine light was off, but now it came back on again. Any suggestion's?

Do not top off your gas tank. The gas is going into carbon canister which is only for fuel vapors to go into (carbon canister opening near the top of fuel neck near the gas cap). Your flooding the fuel vapor canister with liquid fuel; of course you are going to get a sensor message... 'Evap emmission,control sys leak

P0443 The fuel vapor canister reduces that gas smell on hot days outside/inside of car. The fuel vapor canister fillers bad smells from gas tank on hot days when the gas expands and burps fumes through carbon canister filter. From the canister (gas vapor fumes) goes back into the engine to be burned again...it's a closed loop for vapors to be recycled though engine. Don't worry, once the carbon canister dries out and no longer flooded with raw fuel the code should go away...just don't let the top off fuel tank back flow into the 'Evap emission control' carbon filter near the top and close to the gas cap...:)

Check your gas cap. If it's not on properly, missing or defective it will cause the problem you describe.

If they forgot to tighten the hose clamps on the hose from the tank to the filler cap it could be setting it off. If they are all tight it was probably just the gas cap. The gas cap is usually ALWAYS the culprit. Let me know if this helps

If your check engine light came on shortly during or after filling the tank, and then goes off later, thats quite a relief. It really happens, and lucky for you dont have to bring your vehicle to a shop if the light persisted. Here are some tips regarding this issue: turn off the ignition switch before opening the fuel tank cap. Turn on and start only after the caps are properly closed. The scenario is that, whenever we refill gasoline on the tank, the pressure and the vacuum inside the tank are being upset, sometimes creating some kind of signal glitch which may be misinterpreted by the engine control module, and thus shortly illuminate the check engine light. I hope this lightened you up. Have a safe trip. : )

Have vehicle scanned for codes at Autozone its free and do the repairs the codes list.

Because your vehicle is a 2008 I feel it shouldn't be anything to pressing but still take some precautions.

What alot of people don't know is sometimes if the gas cap is not put on tight enough a little air might get in or your gas pump might have to work a little harder because it can't get full vacuum pressure with the cap slightly open. these are not major issues.

these are reasons why your check engine light comes on. It happened to my 2005 Buick Rendezvou We had the check engine light on for a week. The car never shuttered, stalled, delayed starts it ran perfectly fine. I took it in to check engine light their computer showed that it was the EVAP system which is the heating and cooling system I would have to get it checked for leaks or do a static check for leaks.

This didn't look good but then one day I had done some work for a friend told him of my problem he told me it could be my gas cap. The next day I asked my wife if the gas cap was working on vehicle it actually was broke I replaced gas cap and the check engine light came off.

Now with this story (which is true) don't assume every problem could be this. But if you are not noticing any stalls, delayed starts, shuttering anything out of the ordinary check the cap at times to make sure it is closed.

If you keep on having light on and replaced cap or made sure was securely on then take and get it checked out.

Most vehicles will sense that the tank is not sealed, will turn on a light. Depending on the make of car, may have to drive several hours, several starts, etc. before it resets itself after you correct the gas cap problem.

A week ago, on my Lexus ES 300 (2001), "Check Engine" and "Trac Off" lights came on. This coincided with me filling the gas tank to the brim to round the dollar to be paid. I cleaned the gas tank cap and the tank opening. However, both lights persisted. On the same day, when I turned on the car again, there was a hesitance, a stuttering to come on. Both "Check Engine" and "Trac Off" lights were still on.

The next day, the car wouldn't come on at all. It sounded as the battery was dead. I couldn't even jump start the car. So, I got a new battery from Costco ($59) and put it in. It took 15-20 seconds of cranking to get the car started. Once it was started, the engine sounded fine and the RPM normal. The "Check Engine" light was off. However, the "Trac Off" was still on. I cleaned the gas tank cap one more time.

The next morning, when I turned the car on, there was no problems. It came on instantly as it used to be, didn't have any warning lights, and drove smoothly.

The P0141 code points to the O2 sensor heater circuit. It could be that there is a short in the wiring to the O2 sensor or it could be that the O2 sensor heating element itself is bad. The code is for O2 sensor Bank 1 Sensor 2. Bank 1 means its the O2 sensor connected to the exhaust pipe that runs to cylinder #1. Sensor 2 means that it is likely the O2 sensor after the catalytic converter on the same exhaust pipe.
