Does a 2015 Jeep Grand Cherokee have a gas cap?
The gas cap for your 2015 Jeep Grand Cherokee serves multiple purposes. It prevents gas fumes from being released when you aren’t driving, it seals the fuel system and helps maintain pressure within the fuel tank.
When to use the eSIM on a cold engine?
P0457 – Loose Fuel Cap / Gross Leak Detected: This code is set if the PCM recognizes a leak greater than .090″ following three cold engine startups. On most Chryslers, the ESIM mounts directly to the canister, eliminating the need for a mounting bracket. The ESIM must be mounted vertically.
How is the eSIM different from other leak detection systems?
Unlike previous Leak Detection System, the ESIM does not contain a solenoid. Instead, the ESIM uses two weights, a diaphragm, and a switch to detect pressure differences across a variety of conditions. Interested in learning more about this product category?
What does eSIM stand for in auto category?
Evaporative System Integrity Module (ESIM) Premium Replacements for a Growing Category The Evaporative System Integrity Module, also known as an Evaporative System Integrity Monitor or ESIM, is a key component of the EVAP System on many late model Chrysler, Dodge, Jeep, RAM Trucks, and Fiat vehicles.

Where is the gas cap and check engine light located?
It’s is located in the engine compartment below and near the battery. If the solenoid is found to be ok- then the next best and most efficient way to diagnose this is to have the EVAP System “smoked”. This is where a machine forces smoke through the EVAP system, and the “large leak” will reveal itself.
What happens if the eSIM valve fails to open?
A small leak will be considered inconclusive until the medium/large leak monitor test is run. In addition a key off intrusive test is run where the purge valve is opened for 30 seconds to relive vacuum in the system, if the switch fails to open the ESIM switch is considered to be stuck.
