Hello all. This is my first post and it is in regards to our family's ML320. It currently has a check engine light on and the codes that I read with my scanner were P0446 and P0450.
Now i know what their definition but im not aware as to what the problem might be or were the problem is located.
Any help would be appreciated! Thanks
P.S. The ML has 88,000 miles and a new fuel pump assembley was just installed.
P0446 - Evaporative Emission Control System Vent Control Circuit Malfunction
P0450 - Evaporative Emission Control System Pressure Sensor Malfunction
