    OBD-II code P1494 Leak Detection Pump Switch or Mechanical Fault -what does it mean?

    Do any of you know what OBD-II code P1494 means?

    I found a code list on another website that translated P1494 as "Leak Detection Pump Switch or Mechanical Fault". LOL I see the words but they mean nothing to me.

    Any suggestions?

    "Leak detection pump switch or mechinical failure"
    You were in the area of the ldp solinoid.Its a electrical switch with 2 wires and 2 vacuum lines connected to it.I would follow those lines and make sure the one that goes to the manifold is still hooked up and that you have vacuum to the solinoid.The other line makes its to nvld which is mounted below the steering gear.But first it will go under the air cleaner housing.It will have a plastic or steel line with a rubber hose juction in a couple of places.The rubber hoses will crack and leak and could be the cause of your problem.But retrace your steps to make sure you didn't knock any lines loose.

    Hopefully this helps..

    It does...........I looked at your source. They got their code by replacing the ps reservoir. That's what I did. So I'll go look at the same area and see if I left something unplugged.

    thanks,

    I got the Code #1494 on my 2001 Dogde Ram after changing my air filter. Did I knock something loose or not reconnect something?
