| 2007 Jeep Wrangler Unlimited Sahara 3.8L MIL Lamp on VIN: 1J4GB39187 P0457: Loose Fuel Cap. This jeep sets the gas cap light every time you start the vehicle. I have smoke tested the entire system, I am not finding any leaks. I found the Evap monitor was bad, I replaced, it still sets the code every time the key is turned on. Please help |
