Default Check engine code

While driving a got a check engine and a DEF warning light on my 2018 Equinox turbo Diesel. The DIC informed me I had about 90 miles before I would be limited to 65 mph. After about 20 miles the DIC message cleared up, the DEF warning light shut off. The check engine light remained. I pulled the code. It was P2BAA. I cleared the code and it has not come back in the last 10 days.
When this happened I was driving in hilly and curvy country. Is it possible air got in the DEF line and triggered the fault? Any thoughts?
