My check engine light comes on and flashes I replaced the gas cap it never built up back pressure so I thought it might be why reason it was running so bad .but after putting the cap on and putting the additives in the fresh tank of gas there was smoke coming from the center console it smelled kinda sweet,,well not electrical.And it had very little pick up...HELP
I hate to say it, but your owners manual should say the same thing. When your Check Engine light flashes, DO NOT RUN THE VEHICLE - GET IT CHECKED IMMEDIATELY! Most parts stores can check it free and some garages will as well. Do not run it unless you absolutely need to as you may cause more damage than necessary.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

did you reset codes after every repair ? is it a newer car ? there is a sensor in canister called a netural pressure vapor sensor they tend to leak or stick .causing evap codes , I chased the same code ,it would go out for about a week then come back in my case it was the new gas cap it was the wrong one for my car. it keeped building pressure in gas tank . and could hear it hissss when I would open it fuel up .
You have two problems going on. The oil light is telling you the engine oil pressure is low. If the oil level is full, the sending unit for the light is faulty, or you actually do have low oil pressure. The codes are for a leak in the EVAP system which could be the gas cap but could also be a number of other things. There are valves and hoses that could leak. The engine oil pressure would need to be checked with a mechanical gauge, and the gas tank venting system would need to be tested for leaks.
Could possible be the Fuel Tank Pressure Sensor. It is located on top of the fuel pump. The fuel pump access is located in the trunk, under the carpet, behind the back seat. The AutoZone part number is SU 1390.
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.
Did you change the gas cap with a Honda gas cap? Tighten it at least three clicks?
Also, Honda recommends that you never top off the tank when getting gas (only go to the click-off of the pump; otherwise you can get back flow into the system that will cause the code).
Tightening or replacing the cap will not immediately cause the light to go off; it can take up to three days of driving for the light to reset.
To check if your readiness codes (emission system) are set, turn the ignition to ON (II), without starting the engine. The Malfunction Indicator Lamp will come on for 20 seconds. If it then goes off, the readiness codes are set. If it blinks 5 times, the readiness codes are not set.
You can, of course, try resetting your engine light to see if it will come back on (which it probably will). I believe the procedure is: Turn off the engine. Press and hold the Select/Reset knob (odometer) in the instrument panel, then turn the ignition switch to ON (II). Hold the knob for approximately ten seconds until the indicator resets.
Make sure that the gas cap is the correct one. If the gas cap was replaced with a different style or a locking cap this will set off the check engine light. It can tell there is a problem because it measures the built-up pressure in the gas tank. So the pressure is not building in the tank due to a loose or incorrect fitting gas cap or a loose,cracked fuel line, or bad check valve in the charcoal canister for the fuel tank vapor release line.
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.
