That is an emissions code. It means you have a small leak in one of the lines. Most likely it the line that goes from the engine to the evap canister in the drivers side rear inner fender well.

Troubleshooting code PO442 check engine light on. When I put in gas, gas nozzle keeps cutting off like tank is full


The code PO442 is a small leak somewhere in the evaporative emissions control system, the best way to find that is to take to a shop that does smoke tests for emissions.
As far as the nozzle, try changing the position of it the next time you get gas.

The problem is most likely to be with your vacuum line they put cheap rubber hose for this purpose. You should find a diagram at the front of the vehicle trace the hoses by this diagram. You most likely will find a bad piece of hose.
