I am looking to buy a 2017 Chevy Cruze. Yesterday I filled the tank and a few miles later noticed the check engine light was on. Went by O’Reily’s and the code is P015b. Can that be a loose gas cap?
My car has 11200 miles.

Trouble code P015b is not related to, or potentially caused, by a loose gas cap or any other EVAP system malfunctions for that matter. The code instead relates to degraded performance of one of the engine’s oxygen sensors. In some models of Cruze there is a PCM software update that is relevant to this specific code and there is also a possibility that the sensor on this vehicle is subject to premature contamination. In any event, the code implicates possible degradation in engine efficiency and performance and thus obviously the underlying fault should be fully resolved before buying the car or, in lieu of that, be sure to request an adequate discount to cover any necessary diagnostic and repairs. If you want YourMechanic to diagnose and repair the fault, the recommended service to request is a check engine light diagnostic.
