2011 WRX Prem Hatch

Default 2011 Wrx P021

Well Ive had my WRX for 2 years about now with a protune, turbo back exhaust and aem cai, and on my last road trip (this last week when it was stupid cold) I was on 95 heading north to CT, with cruise set, and cruise disengaged and the check engine light came on. I used my cobb to pull the code and it was P021, I cleared the code and continued on my way ( I checked the oil, and coolant which were all fine, about half a quart low on oil which I topped off.) Started her up and hit the road, I never threw another code but now Im nervous that I have a large problem with my engine thats just waiting to go boom. Any advice on what I can do on my own to check this out?? There is no loss in power, the fuel economy is the same etc.
