    I know with Hyundai (I work there) that there are "dealer specific" codes- they just say ____ needs to be replaced but they are not specific. Like for us, P0300 is random misfire. Doesn't tell you which cylinder. This could be the input or output in the trans, or maybe a wheel speed sensor that goes with abs/traction control? Let me look on Alldata for you...

    I have 2 VERY long cut+pastes for you on that p0500. Looks like a wheel speed sensor issue/ cruise control issue.

    I cannot attach them here as they're too big, and I'm not gonna link to alldata- that would give open access to that account. If you want, I'll email them to ya.

    yeah... kfklucas@gmail.com Its more than that though... Ever since that everything has gone out in a sense... My speedo, gas guage, check engine light, blinkers, reverse light, reverse beeper, my heater is stuck on, and probably a few other things just cant remember now. The only good thing is i drive a manual so i was able to operate it in this condition.

    Well, part of the page I'm sending then goes on to say replace ECM. Sounds like that may be the next course of action.

    i know what the code means....But i do I fix it??
    gas cap is tight changed out the air filter had a K&N but got lazy with the cleaning..Last time oil got on a sensor type thing on the intake and i cleaned it with a q-tip ..I saw a page on how and where it is but cannot find it...does anyone know I'm talking about..

    maybe start your own thread on the p0500 makes it confusing when it has nothing to do with the topic i started....why would you go to this topic and start another??? odd..

    If I'm not mistaken, it should have nothing to do with the intake and cleaning a sensor. This detects leaks in your emissions- usually, a code for a loose gas cap. Remove and replace your gas cap with a new OEM cap. Usually $15 or maybe less. Then drive the car. If this is the issue, the lamp will go away and resolve itself. At 100k+, maybe a bad gasket on the gas cap allowing vapors to escape. Now, do our vehicles have a Canister Close Valve in the back near the gas tank? It allows air into the evap system and diagnoses leaks and pressure issues. Over time, there is a filter inside that will clog and the valve behind it sticks open or closed. If that happens, it cannot check for evap pressure and will trip the codes and CEL. I know it's on Cali Emissions vehicles. Again, I work for Hyundai and have seen this more than a few times.

    And, according to Alldata- there is no P0450 code. Wierd. Must be a generic code that just states "X isn't working" but is not specific as to why. There IS a P0451 and it's the same sensor failing range. I can email the page to you as well. Oh, and it DOES show a canister close valve and charcoal filter. If you do work on your truck back there, you may want to replace that as well. Give me your email address.

    OH, and I don't know what year you have- I used a 2004 v6 4x2. Should be ok for your needs. If not, let me know.
