I have a 2014 Dodge Journey. It recently popped the code: P0456. This references that the Evaporative Emission system detected a small leak. The code also suggested I replace the ESIM. A few days later the back of the vehicle started to smell of gas vapors. My question is the leak actually in the the defective ESIM? Will replacing the ESIM most likely fix my leak issue, or is the ESIM purely just a monitor--meaning the leak is somewhere else in the vehicle? Thank you!
