Bosch 0261222022 Evaporative Emissions Leak Detection Pump

The Bosch 0261222022 Original Equipment Leak Detection Pump is an essential component of the evaporative emission control system (EVAP), designed to detect leaks and ensure proper emissions compliance. Engineered with cutting-edge OE technology as an exact match to original equipment specifications, this module guarantees reliable operation and compliance with emission standards.

How It Works:

The leak detection pump provides pressure so the EVAP system can be checked for leaks while other system valves are closed. The pump comprises several one-way valves, a vent valve, a sensor, a vacuum solenoid, and a spring-loaded diaphragm. It helps detect leaks in the system, ensuring that harmful emissions are properly contained and controlled, thus enhancing the vehicle's overall efficiency and environmental compliance.
