Check Engine light

My '17 F-150 just turned 36,000 miles on it and almost immediately I got the CHECK ENGINE icon on the dash. Is this a "programmed" alarm for something. How do I clear it ?

The check engine light is not preprogrammed to come on at any specific mileage. You need to find out why the light is on.

That's what I was wondering. Stopped by AutoZone and used their scanner. Got a Code PO157 - O2 Circuit Low Voltage (Bank 2, Sensor 2).

At 36000 miles that may be covered by the powertrain or emissions warranty. That code can be set by a faulty oxygen sensor, faulty wiring or a faulty catalytic convertor.
