Bosch 992 906 243 Fuel Vapor Leak Detection Pump EVAP DMTL

The Bosch 992 906 243 is an OEM-quality Fuel Vapor Leak Detection Pump, also known as a Diagnostic Module Tank Leakage (DMTL) pump or EVAP leak detection pump. This component is a critical part of the vehicle's Evaporative Emission Control (EVAP) system, responsible for pressurizing the fuel vapor system to detect leaks that could allow harmful hydrocarbons to escape into the atmosphere.

During a self-diagnostic cycle, the pump draws fresh air through a reference orifice and pressurizes the EVAP system. The onboard control unit monitors pressure changes to identify leaks as small as 0.5mm in diameter, triggering a fault code if a leak is detected.

Key Features:

• Direct OEM replacement — matches original equipment specifications
• Manufactured by Bosch, a world-leading supplier of original equipment emission components
• Built-in self-diagnostic functionality for accurate EVAP system leak detection
• Constructed of high-grade industrial plastics engineered to withstand fuel vapor exposure and a wide range of operating temperatures
• Restores proper EVAP system operation and clears related diagnostic trouble codes (DTCs)
• Helps ensure compliance with emissions standards

Bosch part number 992 906 243 (also referenced as 992906243). Cross-reference OEM part number: 7L0 906 243. Replacing a failed DMTL pump with a genuine Bosch unit ensures precise fit and long-term reliability consistent with the original factory installation.
