What Is a Fuel Vapor Leak Detection Pump and Where is It Located? The primary role of the leak detection pump (LDP) in your car evaporative emissions control system is to detect leaks existing on one or more components: fuel tank.This repair method that applies as well for many cars, additionally there are other potential sources such as hoses going through from here.These pumps have only been around since 2003 but now serve dual purpose not least because most new vehicles can easily find out their leakage levels without risk before installing any new replacement parts into them sucking up air pumped directly against pumping intake manifold volume every time an engine speeds along at high rpm which miss very few times if ever when cold starting idle.

The LDP is normally located on the fuel tank, specifically in the right. This placement allows it to easily watch over the fuel system looking for any vapor leaks. The LDP is located near the fuel tank and in order to access, you have partial removal of the fuel tank that can be difficult depending on your level of mechanical aptitude. It is also near the vapor canister on some models, requiring removal of (for example) the right rear wheel or inner liners to access it. 145
How the Leak Detection Pump Works
The LDPs main duty is to pump pressurized air into the Evaporative emissions system so as leak diagnosis.leak detection pump (ad) If it detects a leak, the car will trigger an engine warning light (CEL) which notifies that your vehicle may need timely attention or repair. An LDP system operates by pressure changing within the system and can be used to efficiently detect any abnormalities that may exist12.
DIY Considerations
If you have basic mechanical skills and tools, this is one repair or test that you could do at home completely by yourself. The catch is that it involves several steps:
Preparation Youll need the following• Tools for opening your safe.• Safety equipment.
The Pump: Few pumps are easy to access, some might even require dropping the fuel tank or removing your ride’s wheel wells.
Testing — Before reinstallation the LDP can be bench tested using a vacuum source and 12 volts if you suspect any problems.
LDP replacement or testing can be a complicated matter for some repair shops, and its correct position as part of the vehicle’s air pollution prevention system must also be considered when dealing with those who have no idea how to replace it.
