The fuel tank pressure sensor is part of the fuel pump assembly and is mounted on top of the tank or inside the tank. It’s part of the evaporative emissions system (commonly referred to as “EVAP”) and reads pressure in the fuel system to detect evaporative leaks, such as a loose or faulty gas cap.

Where is the fuel vapor leak detection pump?
The leak detection pump, also known as the EVAP system integrity module (ESIM), is Mopar Part No. 4861962AB for your car. The ESIM is an emissions control device and is typically mounted on the vapor canister in the rear of the car or very near to the canister.
What is a leak detection pump on a BMW?
A Leak Detection Pump (LDP), also known as a Diagnostic Module for Tank Leakage (DMTL), is a vital part of this system as it helps the EVAP find if there are any leaks.
What happens when a leak detection pump fails?
The check engine light or the malfunction indicator light turn on if there’s an issue with the Leak Detection Pump. A diagnostic trouble code should register in the vehicle’s memory because of a poorly working pump.
What is a BMW DMTL pump?
The system utilizes the DMTL/LDP to vent the fuel through its internal vent solenoid and is also used to pressurize the system while checking for leaks. The DMTL/LDP contains a spring loaded diaphragm which moves up and down by a solenoid that controls engine vacuum.
How much does it cost to replace a fuel vapor leak detection pump?
The cost of an aftermarket leak detection pump replacement ranges from around $10 to a little over $100 on average. The exact leak detection pump cost will depend on the model of your vehicle. For labor, expect to pay an additional $100 to $250 depending on the typical labor rates in your location.

What is the code for leak detection pump?
Engine code P2401 is triggered when the Engine Control Module (ECM) detects a leak in the detection pump within the EVAP control circuit. The EVAP system is the anchor that regulates system pressure and gas flow in the engine.
Why is leak detection so expensive?
Why is leak detection so expensive? There is no one process for leak detection. The high price comes from using many different devices and products to locate the issue. You don’t want to go for a budget option when it comes to leak detection in your home.
Will an EVAP leak damage engine?

Does EVAP leak affect gas mileage?
Decreased Gas Mileage When a canister purge valve doesn’t open as it should, your gas mileage might be negatively affected. The vapors in your car used in combustion will go to the EVAP canister then get vented out into the environment, causing you to use some of the fuel that your car would usually use for burning.
Will an EVAP leak make my engine run rough?

How do you reset the fuel pump sensor?
Turn the ignition switch on and hold the “Trip/Odo” switch for about two seconds. Then, release the “Trip/Odo” button, press it again (do this three or four times), and finally hold it for about four to five seconds until the leveling information shows on the Odometer. Then release the “Trip/Odo” button.
How much does it cost to replace a fuel pump sensor?
