P0455 Large EVAP Leak Explained “No Smoke”
In this video, I go into detail on why a p0445 large evap system leak sets and hoe the gas vapor system works and why it will set a p0455.
There are a number of different reasons that could cause a p0455 and the #1 reason being the evap vent valve and they are pretty easy to test. In this video, I will be testing the vent valve and the
evap purge valve with a power probe http://amzn.to/2FN2r70
I will active them with the power probe then blow into them to make sure they are sealing properly. And if they don’t that will be the cause of your large EVAP leak. The vent valve is very common and I hope this video helps a few people save a little money on their auto repair bills. Thanks for watching the Fate Rate Mechanic.
