Genuine 90910AF005 Leak Detection Pump Sub-Assembly for Charcoal Canister

The Genuine 90910AF005 is a leak detection pump sub-assembly designed for use with the charcoal canister in the evaporative emission control system (EVAP). This vital component is responsible for identifying and signaling fuel vapor leaks by pressurizing the EVAP system and monitoring for any drops, helping ensure that fuel vapors remain contained and are routed to the engine for combustion instead of escaping into the atmosphere.

Key Features:

• Primary function is to detect any leaks within the EVAP system and ensure it remains sealed
• Pumps pressurized air into the EVAP system to diagnose any leaks that may be present
• Periodically pressurizes the EVAP system to a specific level and checks if the pressure remains stable
• Helps ensure compliance with regulations set by agencies like the Environmental Protection Agency EPA and California Air Resources Board CARB
• Replaces part numbers 9091014002, 90910AF001, and 90910AF002

This process is essential not only for maintaining emissions standards but also for protecting the environment by reducing pollution. By pressurizing the fuel system, the evaporative leak detection pump allows the engine computer to detect any leaks which may be permitting gas vapors to escape, and when a leak is detected, the Check Engine Light will illuminate. This component is included with the vapor canister.
