Question about 2012 Buick Verano
Check engine light comes on @ any time - I'm not sure what I'm doing or what causes this - AutoZone gave me this code - how do I fix
There is usually another code set with it usually p0231. Can someone check it again to see if there is another code because it is odd that this code set alone. Anyway, the fuel pump control module has to be checked. The usual causes for failure, beside it being the module, is loose or corroded connections, broken wiring, bad ground and just general problems to cause the module from getting the proper electrical connections. DON'T JUST CHANGE THINGS!! Diagnose first.

The cap might need a pressure check. Just because it stays on and tight doesn't mean it is functioning properly. It must meet EPA standards to function properly. Your cap is special part of your emission system and if it is not working properly you will need to replace it and have the light reset. If you owed a code reader it would tell you the same. Auto zone does do free code reading. The check engine light usually is not a big problem,but... I will leave it at that.

The check engine light
comes ON.This light comes because there is any error code saved in cars
computer.In this case the car needs to be scanned.You can get your car scanned
at car diagnostic center like www.autozone.com or at your local car garage.
Once the car is scanned the error code will be detected so as per that you can
get the part replaced.At autozone service center its absolutely free to get car
scanned.Because the engine light is on,its advisable to get car scanned.
