Re: showing a DTC P0446
I had the same code, 4 times in the last 2 months. Had the dealer replace a few parts. I will PM you the parts they replaced. The last one to get replaced was the evap canister. It was coverd in mud. I know a sensor near the gas tank too. Again, too much mud. I will check my paperwork in the morning. If you reset it, I doubt the problem will go away.....lol. Better to fix it right IMO. Been a week, and so far so good. Seems like every 700 miles or so it would kick on.
