How to clear codes?

How do you clear codes, currently have a P2146

 

[Cattletrkr]

Leave it alone, it'll clear itself... eventually. Something like 100 key cycles. Mine has thrown the 2146 and 2149 a couple times. If it's just a blip, they go away quickly.

Where are the codes displayed?

Cycle your key three times. The third time leave it on. Don't start the truck. The codes will be displayed on your odometer.
