I have a 2002 with code p1457, what is the easiest way to fix the problem?
The most common cause of that code is a loose gas cap. Try tightening the gas cap and waiting a few days for it to clear. If you don’t want to wait for it to clear you can disconnect the batteries negative battery cable for a few minutes then reconnect it and it will reset it. Make sure though that you have the radio’s security code before you disconnect the battery cable if the radio is original or the radio won’t work again.
