P2138 code

[zeddy]

Last Sunday, took a road trip to Palm Springs (200+ Mile trip). When I was about to back into a parking spot, my dash started flashing the red lightening bolt symbol. Lightening bolt went away and CEL came on

After driving around the next day, CEL went away.

Truck ran great entire time.

We got back home on Thursday and still noCEL. Hooked up a scanner and p2138 popped up. Erased the code and dove to San Diego (200+ mile trip). After getting home Sunday, hooked up the scanner, and no code. Thinking it was just a hick up?

I have the pedal commander 3 year and never had issues.
I also cleaned my air filter prior to heading out on our first trip.

Wish I knew why it threw the code.

Mine did that a while back, but it was a one time code, after I reset it it was great and dandy.
