Product Overview

The vapor canister leak detection pump, OEM number 04891685AA, is fitted to the Jeep Patriot, covering the 2007-2014 production run, and also fits related Chrysler, Dodge, and Jeep models sharing this evaporative emissions component. Since this pump is part of a widely shared Chrysler Group evaporative system design, it's a steady-demand part number for distributors serving Chrysler, Dodge, and Jeep emissions parts markets. Note that this part number has since been superseded by 04891685AB in the current Mopar catalog.

A worn or failing leak detection pump typically shows up as an illuminated check engine light with an EVAP system trouble code, a fuel odor near the vehicle, or a failed emissions test. GSK Auto manufactures this pump to OEM specification at our Ningbo, China facility, with every unit tested before packing. We supply at wholesale volume with low MOQ and support private label packaging, with our team available to confirm fitment before shipping.

What Is a Vapor Canister Leak Detection Pump?

Function: The vapor canister leak detection pump tests the evaporative emissions system for leaks by pressurizing the system and monitoring for pressure loss, helping ensure fuel vapors are properly contained and not released into the atmosphere.

Working Principle: The pump periodically pressurizes the sealed fuel vapor system and monitors the pressure over time. If pressure drops faster than expected, the module signals the engine control unit that a leak is present somewhere in the evaporative emissions system.

Importance: On a modern emissions-controlled platform, a properly functioning leak detection pump is essential for passing emissions inspections and ensuring the evaporative system doesn't release fuel vapors into the environment.

Common Failures & Signs: Illuminated check engine light with an EVAP system leak trouble code. Fuel odor noticeable near the vehicle. Failed state or local emissions inspection. Intermittent EVAP codes that come and go with fuel level or temperature changes.
