Evaporative System Integrity Module Detector – Mopar (04861959AD)

The Mopar Evaporative System Integrity Module Detector (04861959AD) is a Genuine OEM emissions control component engineered to monitor and verify the integrity of the vehicle’s evaporative emissions (EVAP) system on compatible Chrysler, Dodge, Jeep, and Ram models. This module plays a critical role in detecting leaks within the sealed fuel vapor system, helping ensure proper emissions compliance and fuel vapor containment. Manufactured to strict Mopar factory standards, it delivers accurate diagnostics and reliable system communication.

The EVAP system integrity module typically incorporates a pressure or vacuum sensor, internal pump mechanism (application dependent), and integrated electronic circuitry within a sealed housing. The module performs self-tests by creating controlled pressure or vacuum conditions within the EVAP system and monitoring for leaks. Its durable construction is designed to withstand temperature fluctuations, moisture exposure, and underbody environmental conditions.

The 04861959AD EVAP integrity module detector is developed as a vehicle-specific direct-fit component, matching original electrical connectors, mounting points, hose ports, and calibration parameters. Maintaining OEM programming and pressure calibration is essential to ensure accurate leak detection and proper communication with the engine control module (ECM). Non-OEM modules that do not meet factory specifications may trigger check engine lights or produce inaccurate diagnostic readings.

For professional technicians, installing a Genuine Mopar EVAP integrity module ensures adherence to manufacturer emissions standards during EVAP system service or repair procedures. For experienced DIY vehicle owners, selecting the OEM module eliminates compatibility uncertainty and restores factory-level diagnostic functionality without modification.

A properly functioning EVAP integrity module supports accurate leak detection, emissions compliance, and consistent fuel vapor management. Replacing a malfunctioning or fault-triggering module promptly helps prevent recurring warning indicators and ensures dependable emissions system operation.

• Genuine Mopar OEM EVAP system integrity module
