P1494 (M) Leak Detection Pump Sw or Mechanical Fault Incorrect input state detected for the leak detection pump (LDP) pressure switch

whats this mean and how do I fix it? :help:

The leak detection pump pressurizes the fuel tank when the truck sits overnight. If it sees a pressure loss faster than it's supposed to leak down, it sets codes for EVAP system. P0455 is one of them...I know this since it's happening on my D right now. I had a friend with a smoke machine force smoke thru the EVAP port and the solenoid on the leak detection pump is the cause of the leak. It's easy to change and should be located right in by your battery. They list for $105 according to AllData.

If you need more help, just give a holler.

Engine Code

First I would like to thank SinCity R/T for posting this info. :clap2:

After some fiddling, I was able to get the following code:

P0455 (M) Evap Leak Monitor Large Leak Detected A large leak has been detected in the evaporative sysem.

Now, what the heck does it mean? :help:

I thought I would mention this for the people that were having trouble getting the code check to work.

I had to turn it on each time until the odometer read then shut it off, repeat.

if you do it really fast it won't work.


P.S. same thing for the 80's turbo dodge's

Electrical problem in my 2001 Durango

I hope I'm bringing a question that fits this board. . . please redirect me if necessary. I'm having trouble with my 2001 Durango. It first began with the factory alarm. Whenever we disarm the alarm the horn would honk 3 times. But now I have no headlights, domelights, door locks and the alarm system completely doesn't work. My dealership had no idea what might be wrong. Any suggestions?

 

[Sicminds0088]

making a new post would be an easier way to get help. Personally, I have no idea what the problem would be. try posting this here.

 

[Drivernumber22]

Can we sticky this? I allways gotta search for this but I love this!

I Tried It But All Mine Said Was P Done Is That Good?

 

[Aaron001]

[Sabbath]

That is good, it means there are no recorded errors.

1999 and earlier Dakotas/Durangos must be read with a scanner, check your local dealership or auto parts store for assistance.

the same method works for earlier model Dakotas; mine is a '95 and I just used the method and typed in the numbers at that site.

This system should work for ALL OBD I Mopars, and newer model OBD II's. Its worked on all my gen I daks and folks old 96 Intrepid, and my Jeep Grand, and FYI(those who don't know) OBD I is first gen on board diagnosis systems used up until 96(I think) and OBD II used there after. And OBD I codes are different and the check engine lights flashes a code to you. I wish my 97 R/T QC had the built in code viewing sys, makes life a hell of alot easier.
