The check engine light came on while this car was under warranty, the dealer fixed whatever parts necessary twice. Then the third time they couldn't figure out why it was coming on and said it wasn't an issue. This was in 2008 and 2009. In 2012 I failed an emission test in Idaho with codes P0068, P0446, and P0171. I had a waiver and now it's time to get it tested again and the codes I received are the same three as above plus P0507, and P0116. Seriously, was this stuff the dealership didn't fix when it was under warranty? Can I fix these myself? How hard is it?
-I hate to say that but absolutely NO. If you don't know much about car. All these codes are emission code.
P0068 Mean Throttle position sensor.
P0171 Mean system too lean.
P0446 Mean evaporator emission control system has not correct flow
P0507 Mean Idle air control is too hight.
P0116 Mean engine coolant temperature.
Need to have a mechanic to check one by one to determine which part is effect before replace it.
Good luck

Testimonial: "Thanks you and I appreciate your response but you listed what the codes are and I know what each one is in regards to their name. I have a friend who used to be a mechanic but that doesn't answer my question if it's cheaper to get parts for each code or do I have to take it in? Clearly the dealership couldn't even fix it the first two times when they said they did so I would like more possible options other than taking it back in, if it can be done itself."
SOURCE: Engine Light on got 3 codes
Fix the leak at the emissions system first. There is a small leak that the PCU detected. That could be the cause of the P0116 problem. Also the PCU detected a lean gas mixture because it is getting more air to the fuel system than gasoline. Start with the leak , then the Engine temperature sensor. I think that fixing the lek will "fix' the othe 2 problems. but it could be either one or all of them.
SOURCE: Car won't start
k is there power to fuel pump? yes,,, check grounds..... NO check relay only get kia relays for main and fuelpump since o2s run on the same relay,..... if relay is good suspect comp.... mine has same problem with no power to fuel pump i have now traced problem to ecu sux but at least it has a new fuel pump and relay lol.....

You'll need to have the car scanned and get the OBD II P Code. Most auto parts store will do it for free. That will tell you why the light is on.
SOURCE: My check engine light came on after getting gas a
try unhooking the battery cable longer then 30 sec try at least min of 5 min or so it should reset if not then u have some other issues with emissions but it is always a good practice to always turn off vehicle when getting gas to keep from this happening
SOURCE: fails emissions with fault code p0446.. how do i
P0446....Evaporative Emission Control System Vent Control Circuit this vehicle should not have failed with this code ,its a rubber pipe perished or split ,short answer ice road truckers is back on after adverts sorry
