I brought my car brand new in 9/30/1999. I have 62,138 miles on it. My check engine light came on 05/09/2009. I checked the gas cap, oil etc..could not find anything. I just drop off the car this morning to the repair shop for assistance. I was just advised that I need a Leak Detection Pump. What does that do??? What happend to cause that problem?? and On average how much does that cost???

    I think that the leak detection pump is a part of the evaporative control system, which manages evaporative emissions. It's a part of the emissions control system, and it would definitely cause the check engine light to come on if it fails or isn't working correctly.

    It's not terribly uncommon to have this sort of problem on Chryslers. Unfortunately, I'm not sure how expensive a part that is.

    Mine just went on my 2001 300M. The part is about $130.00 (although saw it online for about $90.00) and labor is about $150.00.

    The Check Engine Light (CEL) is a warning indicator—it means your vehicle's computer has determined that a component or system in your emission control system is not working properly.When the light comes on, one or more diagnostic trouble codes (DTC) are stored in the engine control module. These DTCs remain even if the light goes out. To address a Check Engine Light problem, the DTCs are retrieved and the appropriate troubleshooting information is followed in order to determine the problem.
    so you need some fault code reader to read out the trouble code and erase them till your check engine light off. I don't know whether you can do DIY repair or not. For DIY work, I recommend you use US703 code reader, and more workshop use Starscan for Chrysler.
