    The EVAP leak detection is called the ESIM or Evaporative System Integrity Monitor Switch. It is located on the rear of the EVAP canister mounted on top of the fuel tank. If you are under the vehicle and looking up at the rear of the tank you will see the ESIM Switch and the vapor canister hose attaches to the ESIM itself.

    Does eSIM have a solenoid?
    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. The PCM uses the ESIM in several conditions. First, when the vehicle is running, the EVAP system is pressurized due to natural vapor pressure.

    What is a Chrysler eSIM?
    The Chrysler ESIM is essentially a switch that closes when the vacuum in the tank exceeds a specific pressure (typically 1” H 2 O). Imagine the vehicle moving around and fuel sloshing around or sitting in the sun all day.

    What is eSIM Assembly?
    The ESIM assembly consists of a housing, a small weight and a large weight that serve as check valves, a diaphragm, a switch and a cover. There is one large weight and one small weight check valve in the ESIM assembly. A seal is attached at the end of each weighted check valve. The large weight check valve seals for pressure.

    What is the difference between NVLD and eSIM?
    The ESIM (Evaporative System Integrity Monitor) is very similar to the NVLD. However, the design of the ESIM has been simplified and unlike the NVLD the ESIM does not require a solenoid. The ESIM mounts directly to the canister, eliminating the need for a mounting bracket. It is critical that the ESIM is mounted vertically.

    What happens if the eSIM weight is sealed?
    The ESIM weights seal the evap. system during engine off conditions. If the evap. system is sealed, it will be pulled into a vacuum, either due to the cool down from operating temperature or diurnal ambient temperature cycling. When the vacuum in the system exceeds about 1” H20, the vacuum switch closes.
