Ya, so ugh, my car is throwing a P0442. I know its( Evaporative Emission Control System Leak Detected (small leak)), but I don't know where to find this. Any one have any clues to where this is?

 

Egr?

 

Ya, ugh? Anyone? My car sucks.

 

did u tighten the gas cap tight enough? it can cause the code if the cap is not tight enough. if it tight enough then somewhere in the EVAP system there a leak.

 

Ya the cap is down good, but yet..wtf is the evap system?

 

it capture the gas fume inside the fuel tank and rout it back to the engine to burn instead of releasing it to the outside.

 

its the gas cap..have the CEL cleared and it shouldnt come up if the cap is tight.

 

I have the same exact issue with my mom's Lancer. It's throwin the same exact code. Disconnected the battery for a few minutes, made sure the gas cap was tightened, and the light came on again after a day of driving.

 

Ya, this is the 3rd time it came on, I originally thought it was a misfire code, but I scanned it with my friends creader and its still there. It likes to come back. I'll take a more in depth look tomorrow.

 

usually the gas cap is the easy fix, bummer that its not working for you!

mine came on last week, but i just retightened the gas cap, cleared the code and so far no problems.

 

my thoughts are maybe the cap has a crack in it or something, possible?

 

when i used to work at lexus, ppl will have the same problem and then tighten the cap and still complaint that the light was still on lol, make sure you disconnect the battery!!!

 

anyother solutions? or where to check for the error? other than the gas cap? i am having the same issue.

thanks,

 

Did you install a walbro fuel pump recently?
