OE Aftermarket 1K0 201 797 B OEA Evaporative Emissions Vapor Canister

The OE Aftermarket 1K0 201 797 B OEA is a replacement evaporative emissions vapor canister, also known as a charcoal canister or EVAP canister. This component is a critical part of the vehicle's evaporative emissions control system (EVAP), designed to capture and store fuel vapors from the fuel tank to prevent them from escaping into the atmosphere.

Function and Purpose:

The vapor canister contains activated charcoal that absorbs fuel vapors when the vehicle is not running. When the engine starts and reaches operating conditions, the EVAP system purges these stored vapors back into the engine to be burned during combustion, reducing harmful emissions and improving fuel efficiency. This canister is typically located in the rear of the vehicle near the spare tire area.

Key Features:

• Direct replacement for OEM part number 1K0 201 797 B
• Also replaces superseded part numbers: 1K0 201 797 AB, 1K0 201 797 AE, 1K0 201 797 R
• Compatible with 22mm fuel filler neck systems
• Durable plastic construction designed for long service life
• Manufactured to OE specifications for proper fit and function

Common Failure Symptoms:

A failed vapor canister often triggers a check engine light with EVAP system codes. While there may be no other noticeable symptoms, a faulty canister causes the vehicle to operate inefficiently, produce higher emissions, and may result in fuel odors or difficulty passing emissions testing. Replacing a defective canister restores proper EVAP system operation and helps maintain optimal fuel economy.

What's Included:

• One (1) evaporative emissions vapor canister
