Pt Cruiser Leak Detection Pump Location

The Leak Detection Pump (LDP) on a Chrysler PT Cruiser is located near the fuel tank, which is situated at the rear of the vehicle. It is mounted to the frame rail and can be accessed by removing two bolts that secure it to its mounting bracket. The LDP works in conjunction with an evaporative emissions system and detects any hydrocarbon vapors that may escape from the fuel tank or other components.

It then sends this information to a control module for further processing before being sent to other parts of the vehicle’s computerized systems. The LDP also helps ensure proper operation of your vehicles emission control system, improving its overall performance and aiding in protecting our environment from excess emissions.

The Pt Cruiser leak detection pump (LDP) is located on the passenger side of the vehicle near the firewall. The LDP is responsible for detecting fuel vapor leaks in order to protect the environment and keep your car running safely and efficiently. It’s a good idea to check it from time to time, especially when you are doing regular maintenance on your car, as it may need replacing if it becomes worn or damaged.

Where is the Leak Detection Pump?

The leak detection pump (LDP) is located in the evaporative emission control system of a vehicle. It is used to detect fuel vapor leaks from the fuel tank and other components in the system. The LDP is mounted on or near the fuel tank and contains an electric motor, impeller, float switch, pressure chamber, and one-way check valve.

Its purpose is to detect any leakage in the evaporative emission control system by creating a vacuum within it that draws air through its mechanisms. This allows for the detection of vapors escaping from any part of the system where there may be a loose seal or gasket. If detected, this can prevent hazardous vapors from entering into engine intake manifold as well as reduce harmful emissions released into our environment.

How Do I Know If My Leak Detection Pump is Bad?

If you suspect that your leak detection pump might be bad, the first step is to perform a visual inspection of the unit. Check for any signs of physical damage or corrosion and make sure all connections are properly secured. Next, test the electrical components by using an ohmmeter to measure continuity between each component.

Additionally, inspect hoses and other parts for visible signs of wear and tear such as cracks or holes in them. If there are any noticeable problems with these components, it’s likely that your leak detection pump will need replacing. Finally, check if the pump itself is functioning correctly by activating it manually and testing its response time against manufacturer specifications – if there is a delay in response time then this could indicate that something is amiss with your system.

If you find yourself unable to identify any issues on your own or don’t feel comfortable performing these tests on your own then seek professional help from a qualified technician who can diagnose the problem accurately and provide an appropriate solution quickly.

How Does a Chrysler Leak Detection Pump Work?

The Chrysler Leak Detection Pump (LDP) is a fuel vapor recovery system installed on most Chrysler vehicles. It detects evaporative emission control system leakages and helps reduce harmful hydrocarbon emissions from the vehicle’s exhaust, thus protecting the environment. The LDP works by creating a vacuum that draws air through the fuel tank and charcoal canister.

The air passes through the hose connected to an activated carbon-filled filter where hydrocarbons are absorbed into it. When the amount of hydrocarbons reaches a certain level, it triggers an electrical signal to activate a purge valve, which then releases some of these hydrocarbons into the engine intake manifold so they can be burned off during normal combustion rather than being released as pollution. As long as there are no leaks in your vehicle’s evaporation control system, this process will keep you compliant with environmental regulations while helping improve your car’s performance and efficiency at the same time!

What is the Evap System on a Pt Cruiser?

The EVAP system (or Evaporative Emission Control System) on a PT Cruiser is designed to control the evaporative emissions from the fuel tank and associated fuel lines. This system helps reduce harmful pollutants that are released into the atmosphere by preventing volatile organic compounds (VOCs) and hydrocarbons from escaping into the environment. The primary components of this system include a carbon canister, purge valve, hoses, vents, pressure sensors and other specialized parts.

The carbon canister stores any vapors generated in the fuel tank before they are drawn off through the purge valve when certain conditions are met. From there, these vapors travel through hoses to be routed back into your engine’s intake manifold where they will be burned as part of your normal combustion process rather than being released into our atmosphere as pollution. In addition to helping protect against air pollution, it also helps maintain proper engine performance by ensuring that the right amount of air-fuel mixture is present within your cylinder heads at all times for maximum efficiency and power output.

2015 Chrysler 200 Leak Detection Pump Location

The Leak Detection Pump (LDP) on the 2015 Chrysler 200 is located in the evaporative emission system. It monitors the fuel vapor leakage from the fuel tank and sends a signal to prevent further leakage if any is detected. The LDP is typically found near or attached to one of the hoses connected to the charcoal canister, which stores fuel vapors released by your engine until they can be burned off during normal combustion.

Where is the Leak Detection Pump Located

The Leak Detection Pump (LDP) is typically located near the fuel tank of your vehicle. It monitors the evaporative emissions system and identifies any leaks that may be present in the system. The LDP will then activate an alert light or signal if a leak is detected, providing you with an early warning so you can take steps to have it repaired before further damage occurs.

2002 Chrysler Town And Country Leak Detection Pump Location

The Leak Detection Pump (LDP) on the 2002 Chrysler Town and Country is located underneath the hood near the firewall on the passenger side. It is mounted to a bracket that attaches it to the vehicle’s frame, and its purpose is to detect fuel vapor leaks from both evaporative emission control systems and crankcase ventilation systems. To access it, you may need to remove some of the components around it first.


In conclusion, the location of the leak detection pump on a Pt Cruiser is important to know as it plays a vital role in controlling emissions from your vehicle. Knowing how to access and replace this part can save you time and money by avoiding costly repairs that could be caused by a faulty pump. Additionally, being aware of the potential issues related to this component can help keep your car running efficiently for years to come.
