0455 - Purge system major leak - want to fix, need guidance
 

Hello, fellow MB owners,

I have a CLK320 here, that has been relatively trouble free for almost a year, however, now have a problem: Check Engine is on.

I have purchased a simple code reader/eraser from fleabay, and have been receiving consistent reading of the same code:

0455 Purge system major leak, fuel tank pressure sensor voltage supply

I have searched several topics, and while there seems to be fair amount of info out there, my expertise is somewhat limited to mechanical tasks, such as replacing struts, brakes, or other non-electrical components.

What do I need to replace?
Anyone willing to hold my hand?[/align]

I have replaced gas cap, still the same problem happening - LOW FUEL INDICATOR FLASHING, Check Engine is not on, but the code is there (0455).

What should I try next considering I do not have access to smoke machine?[/align]
