What is DMTL leakage?
The DMTL is activated as air is pumped through a restrictor orifice 0.3937 inch = 1.0 mm (0.040 inch leak) or 0.01969 inch = 0.5 mm (0.020 inch leak) that causes the pump motor to draw a specific amount of amperage.
What does a DMTL pump do?
The DC Motor LDP ensures accurate fuel system leak detection for leaks as small as 0.5mm (. 020”). The pump contains an integral DC motor which is activated directly by the engine control module. The ECM monitors the pump motor operating current as the mea- surement for detecting leaks.
Where is the DMTL pump?
DMTL pump is easy to replace. Just remove the panel under the passenger side rear, remove the 3 or 4 screws for the carbon canister, then you can drop that down and see the pump on the front side of the canister.
What is the DMTL?
Originally developed by Bosch in the late 1990s, the name of the device translates as “diagnostic module for tank leakage,” or DMTL. It consists of a small vane-type air pump on a 12-volt electric motor and a solenoid-operated switching valve with a reference orifice.

What is a fuel evaporation leakage check?
An Evaporation (leakage) test uses your car’s fuel pump to pressurize your car’s system to test for tiny leaks. If a leak is found, your car will throw a Check Engine Light. The problem might be as simple as a loose gas cap or there’s an actual leak, it’s size, as small as a pin head.
How do you diagnose an EVAP leak?
Smoke Test – The idea behind the smoke test is simple, blow smoke into the EVAP system and look for smoke escaping from a compromised valve, seal, tube, or hose. Smoke testing is the best way to test the EVAP system. At the same time, it’s also either the most expensive or bravest method of doing to.
How does an EVAP leak detection pump work?
This system works by pumping pressurized air into the EVAP system to test it for leaks. The pump has a series of one-way valves and a vent valve, a sensor at the top, vacuum solenoid and a spring-loaded diaphragm. It uses an engine vacuum to move the diaphragm up and down.

What is code P2402?
Code P2402 is an indication that the evaporative pump is shorted internally and other than failing emission tests and the check engine light being on, should not cause any drivability problems.
