You cannot retrieve the the code until it pops up again. Have to wait for the check engine light to come on again.

I had the same DTC. It happened after I got gas in my vehicle one week ago yesterday. I took my 2017 Escape to the dealer service area. They were able to retrieve the code in PCM. It was Crank Case Pressure Sensor. Funny thing, on the way to the dealer, the engine light went off. They checked the voltage and said it was normal. They reset the PCM. I got gas in my vehicle again yesterday, today the engine light was back on.
