got a code here just wondering what it could be, P0455, its a 2008 mazda 6 2.3L 5 door.

definition: EVAP control system leak detected- large leak.


when i printed it out it said the probable cause could be:

1.faulty fuel cap,
2.canister faulty
3.purge valve solenoid faulty
4.damaged/leaking EVAP hose
5faulty EVAP leak detection pump

thats all the ticket read out. so any help before i send her in would be awesome!

 

Well hopefully it's just the fuel cap is faulty and replacing that fixes the problem for you.

 

ok thanks for the info, ill go get a new one and hope it fixes it

 

check to make sure the gas cap is on tight, usually 3 or more clicks. I've had this happen twice where I didn't screw the gas cap on tight enough. If that's the case the engine light we'll go off after awhile.

 

+1 always start with the cheapest & simplest solutions.

 

hey you know i am having the same problem rite now. 5faulty EVAP leak detection pump i went to my dealer service and they charged me $90 to tell me that, you have problem of evaporation leak detection pump and needs to be replaced. he said that it will cost $600-$700. but i didnt get it fixed, and its been 8 months and i am not having any problems because of that but that red engine sign is killing. should i get it replaced, and am i paying too much for it?
