If you refer to the emissions sticker on the underside of the hood, it will show you the approximate location of all evap system components, but it really doesn't matter. reprogram means you would have to reprogram the engine computer, which needs to be done w/ a high-end scan tool that you may only find at a dealer

code p0441 refers to EVAP system--incorrect flow detected===causes---hose connections --intake leak--EVAP canister purge valve.
once you fix the fault use a scanner to reset the engine light.

2008 chevy cobalt engine light on


Your Po449 code means: Evaporative Emission (EVAP) Vent Solenoid Control Circuit. Check to see if anything on you EVAP system has gotten disconnected and make sure that none of your hoses have gotten old and bridle or have holes. If everything looks ok, you probably have to replaced the Vent Solenoid Valve, which is located on the EVAP canister.

What is code P0455- Emissions leak


well you can have o'reillys use the scan tool to clear codes in the computer and the light will go out unless the problem still exists then it will come back on. this code means that maybe something is wrong in the evap system. i have a question for youl. when you get gas do you stop when filling up and the pump kicks off the first time or do you kepp filling a little more each time trying to top it off better. what many people do not know is that you can do this but it is filling the lines of the evap system with gasoline which will eventually cause problems with the system. the evap controls fuel vapors from the gas tank and it can not work if it is full of gas. i am sure you understand gasoline turns to vapor quickly. gas in your gas tank does too. to keep it under control the evap system gathers it and purges it with switches and sensors that can be damaged by liquid gas. so can vacuum lines. they will swell and leak and all of these will cause the system to fail and the computer will set a code and the light comes on. also the gas cap being lose while the engine is running will do the same.if that is the problem you will need a skilled tech to figure out what is wrong and replace it. if your getting gas always stop the first time the pump kicks off. hope this helps and good luck

Check engine light comes on, gauges light comes on


What sensors did you replace? It sounds like a problem that could be caused by something in the evaporative emission system, like a faulty purge solenoid or evap cannister problem. Does the tank take fuel slowly when filling up? You could also have a faulty gas cap. That is the first thing I would look at. It is an integral part of the evap system. Hope this helps and best wishes.

Check engine light sensors have been reset but don't show a reading


U will need to drive a mixture of stop and go, city low speed and freeway miles, this can take a week and 20-50 miles or so for the system to finish it's internal self testing. this is called a drive cycle test.

Check engine Light


The P0455 indicates you have a gross vacuum leak in the EVAP system.
Start at the engine and the vacuum purge valve, start checking the vacuum hoses and lines all the way back to the EVAP canister near the gas tank. Make sure no hose or lines are cracked / disconnected.
If all looks OK, let me know and we will proceed from there. Below is a schematic of the EVAP system for reference.
Good luck and let me know.
