• Description:

  The Genuine Mopar 04861959AD Evaporative System Integrity Module (ESIM) is an OEM emissions control component designed to monitor the integrity of the vehicle’s evaporative emission control system. DOES NOT INCLUDE SEAL. Manufactured to Mopar’s exact factory specifications, this module helps detect fuel vapor leaks and supports proper operation of the EVAP system to maintain emissions compliance and fuel system performance.

  The ESIM is a critical part of the vehicle’s evaporative emissions system, which captures and stores fuel vapors from the fuel tank to prevent them from escaping into the atmosphere. The module works with the EVAP system by monitoring pressure and vacuum conditions, allowing the vehicle’s onboard diagnostic system to identify potential leaks and maintain proper vapor control.

  A failing evaporative system integrity module may trigger the Check Engine Light and can result in diagnostic trouble codes related to EVAP leaks, such as small leak detection faults. Other symptoms may include difficulty passing emissions testing or incorrect EVAP system monitoring. Replacing a faulty ESIM with the Genuine Mopar 04861959AD helps restore proper leak detection capability and reliable emissions system operation.

  Engineered with durable automotive-grade materials and precision components, the Mopar 04861959AD is designed to withstand fuel vapor exposure, temperature changes, vibration, and demanding under-vehicle operating conditions. Its OEM design ensures proper fitment, connection, and compatibility with the factory EVAP system without modifications.

  Choosing a Genuine Mopar evaporative system integrity module provides the quality, accuracy, and reliability expected from original equipment components. This OEM replacement helps maintain the vehicle’s emissions control performance and supports proper diagnostic monitoring.
