Generic OBD Vehicle Scanner Code


Asked by Jul 28, 2014 at 08:48 PM about the 2004 Land Rover Discovery SE

Question type: Maintenance & Repair

I have a 2004 Discovery, and the code scanner says: evaporative emission system leak detected (large leak). What could that be?

6 Answers


Could be the exhaust system.


What was the code #?


Sorry, it is P0455


Thank you BohoMark, I did notice the muffler rattling


This can't be as simple as a gas cap can it? I have removed an re-installed the cap, and the service engine soon light remains.


That's a good place to start. And about the least expensive to boot.
