You can get a cheap code reader/code clearer from Amazon (I think mine was ~$45). For me, the code is intermittent and I can clear it on my own. To paul84043's point, the dealer doesn't like to see the rotofab/CAI intakes when you bring them in for these codes (it's easy pickings and I can understand why they don't want to waste technician time if they don't have to). I clear my own codes every few weeks or so when they come up on my car. Anyway, I'm getting them 'tuned out' tomorrow.
