    Roger that, so i got another question about paccar mx13. I have this speed sensor problem and injection problem, so i got to replace two injectors, a common rail pressure valve and two sensors the crankshaft and camshaft sensor. So my question is if there is any place to search and get the accurate replacement according to the motor serial or something like that? Believe me, im so new on this

    Paccar dealer is about the only choice.
    These motors have all kinds of issues even dealers do not seem to be able to fix them.
    I know of one person that spent 14 grand and ended up swapping out the motor from a wreck.
    Mechanics around my area will not work on them. They say they no nothing about them and don't want anything to do with them.

    I'm curious as to why you have to replace both those sensors, 2 injectors, and the pressure valve. When it comes to replacing the injectors, you have to do a calibration and other BS with Davie. The injectors themselves usually aren't difficult to replace unless Murphy comes along and says his piece. The times, parts, and locations will be based on the ESN which can only be looked up by a dealer typically.

    I have been told that the Davie program will only do so much with Paccar.
    Some computer adjustments can only be done at a Paccar dealer with their software.

    They already check it and told me about the replacement of that things, the truck it self have a alarm about stop the motor. The replacements here in my country are a bit more expensive, so im searching them. I was like asking an specific page so i can search the replacement to give me an idea of how it looks. Cause the mechanic will charge more money for just getting the parts out so i can get like a serial or something like that

    Davie is Paccar's OEM software. I'm a dealer mechanic so we use PVP (online tool) to make a lot of parameter changes then send them to Davie to install them. When we're hooked up to a truck, we do the update(s) for the truck and the parameters stick. Davie and ESA (different program for "older" trucks with certain configurations)

    I don't know of any other site that looks up parts by ESN but I also work at a dealer so I can have my parts guy do it for me. Paccar is normally more expensive and some things are ok to use that aren't OEM but it's really best to stick with OEM. I know a lot of people think the mechanics are out there to just take your money but we see what happens with aftermarket vs OEM things like sensors and filters.
