About Fuel Vapor Leak Detection Pump

The leak detection pump (LDP) is crucial because it is responsible for keeping track of any possible leaks. It also activates the EVAP system to carry out a diagnosis and illuminate the check engine light.

Leak detection pump function

The leak detection pump (LDP) identifies any vapor leaks and initiates the check engine warnings. Any small leak that is hard to distinguish is discovered by the LDP, the LDP is a device that controls emission just like the vapor canister. The LDP assembly is composed of several parts like the solenoid, the pump section, and the diaphragm.

Leak detection pump parts

The primary function of the LDP is to produce pressure to the fuel system for leak checking. This occurs by closing the EVAP system vent to atmospheric pressure so that the system can be pressurized. While the pump part of the LDP is made up of a diaphragm that moves up and down so air can be drawn in through the air filter and let out through the outlet check valve.

Common issues with a faulty leak detection pump

A faulty leak detection pump can cause the check engine light to turn on or a diagnostic trouble code could show in the vehicle's memory.
