What does the code p1457 on your car mean?

Answer 1

It means you have a leak in the emmision evap control cannister system. So you are going to need to find the leak. I'll give you a little tip though that Amy save you some time. Check that the gas cap is on all the way. It needs to click three times when you put it on. If it doesn't it can give you a false reading in the evap system. Good luck.
