I have codes 455 and 442 what do I do[/quote:c6c1e0c6e8]
Hello,
Here are the Code Defs....
P0442 Evaporative Emission Control System Leak Detected (small leak)
P0455 Evaporative Emission Control System Leak Detected (gross leak)
You should look for Vacuum Leaks... Open the hood and listen for a Hissing sound and try to locate it, you can wiggle/move the vacuum line to see if it gets louder or not. They can be very hard to find.
