Solving a P0449 Engine Code on a 2008 Chevy Impala (Evaporative Emission System Vent Valve/Solenoid Circuit)
About a month ago my car began showing an engine code, which appeared after I ran out of gas (that is its own story). Using DashCommand on my iPhone, and connecting to my car, I was able pull the following code:
Unfortunately I was unable to permanently clear the code. Every time I cleared it the code then reappeared a second later. So it wasn’t simply a left-over from running out of fuel, though I suppose that perhaps the event itself contributed to the equipment failure.
After doing some “research” via Google I determined that it was a relatively simple part to replace.
