For every 10 degrees the temp drops, you may lose 1-2 pounds (0.91 kg) of pressure. That's because the temperature has dropped and the air inside the pie cools down and contracts. Have you ever baked a nice pie? It might have a slight dome when it first comes out of the oven due to hot air expanding inside the pie.

Not all check engine lights mean you need to stop driving right away, but most of them will require a trained technician to diagnose and fix the issue. While this won’t affect driving right away, it will stop you from passing most states’ emissions certification tests.
This light will also come on when non-critical sensors like exhaust sensors stop functioning. It’s a good idea to pull over and check this out first.
