Where is the leak detection pump on a 2002 T & C?
I have a 2002 T&C with check engine light and the local auto shop has confirmed that the “Evap Pump” is dead. One reference I have says it’s behind the battery and the other says it’s behind the left wheel well. I can’t seem to locate it. Where EXACTLY is the leak detection pump on a 2002 T&C? Do you know what trouble code was reported?
Where is the Check Engine light on my 2014 Chrysler Town and Country?
Just as a re-cap I had a check engine light with my 2014 Town & Country. It was a P0441 code (EVAPT System Incorrect Purge Flow). I had a trip earlier this Spring so I made a stab in the dark and replaced the Canister Purge Valve. It was about $25 at AutoZone and it was easy to access at the front of the vehicle behind the air filter.
What is the purpose of a leak detection pump?
The main purpose of the LDP is to pressurize the fuel system for leak checking. It closes the EVAP system vent to atmospheric pressure so the system can be pressurized for leak testing. The diaphragm is powered by engine vacuum. It pumps air into the EVAP system to develop a pressure of about 7.5′ H20 (1/4) psi.

When does the EVAP system detect a leak?
Malfunction is detected when EVAP control system has detected a very small leak. The Evaporative emissions system is design to prevent the escape of fuel vapors from the fuel system. Leaks in the system, ca allow vapors to escape into the atmosphere. The leak detection system tests for EVAP system leaks and blockage.
How does the leak detection system work on a jeep?
The leak detection system tests for EVAP system leaks and blockage. During the self-diagnostics, the Powertrain Control Module ( PCM) first checks the Leak Detection Pump (LDP) for electrical and mechanical faults. If the first checks pass, the PCM then uses the LDP to seal the vent valve and pump air into the system to pressurize it.
Is the leak detection pump covered under the warranty?
Your car may still be covered under the five year/50,000 mile emissions warranty.If so, you should not have had to pay a penny for that repair since the leak detection pump (LDP) is an emission control device, as is the charcoal canister (also called the vapor canister). If they are bad, there should be no charge for repair or replacement.
How does the EVAP system work on a Chrysler 300?
The EVAP system captures all fuel vapor from the fuel tank and sends them to the engines intake in order to be ignited in the normal combustion process. When there is a small leak in the Chrysler 300’s EVAP system, it will throw the P0456 OBDII Code. If there is a large leak, it’ll throw P0455.
