Yes, agree that perhaps it was an accident of timing. Thanks to everyone for the comments.

The light came on in the same few days that it was cold, and the electronic tail gate kept sticking and sending error messages. Maybe that's an entirely independent issue, but in the strange new world of integrating computer systems, I will see what dealer service says.

My bright spot in this sequence is that I have a nearby Ford dealer where the service department has been excellent.

 

The Check engine light AKA Money light appears due to many many different reasons. By all means have it read but do not reset the light.

Personally, I think everyone should have a OBD2 code reader. They are dirt cheap under $50. These can read generic codes on any vehicle. If you want something that can go deeper and read Ford Specific codes you have to invest more $$$.

 

On a 2023 Ford F150, where does the code reader plug in?

 

The OBD port is under the knee panel, driver's side.

 

Thank you.
