My kia sportage (2000) is giving off code P0505 for idle air system malfunction, exactly what does that mean and how do I fix it?
P0505: Idle Air Control Valve System fault, Code P0505
-Vacuum leak
-Dirty throttle body
-IAC motor defective
-Poor electrical connection to the IAC valve, hope this helps and good-day !

Even though the fuel filter and pump are easy to replace, I would start with the IAC sensor first. It is easier to get to and is cheaper than the other two if you can find one at a wrecking yard (should be around $20). This sensor is the Idle Air Control sensor, and the computer decides how much throttle to give at idle from the readings of the sensor. If it is bad your car will idle poorly or not at all.
You can verify this two simple ways:
1. Disconnect the sensor completely and see if anything changes. If you get the same issue, then it's probably the sensor. If different then it could be fuel delivery.
2. With it all hooked up; try throttling the engine yourself at 1000-1200 rpm and see if it is smooth. If it is then it is probably the sensor. If not then could be the fuel delivery.
The sensor is under the silver and black, plastic KIA cover over the engine (4 small nuts to remove), and is center above the engine on the front side of the intake pipe. 
The part looks like this:
If it seems to still be fuel delivery, the filter is (facing the engine from the front of the car) down to the left and toward the back attached to the fender well (Just to the right of and below the battery)

For that many codes I would refer you to a bulletin covering the 123 and 124 connectors. This bulletin has instructions on how to upgrade these 2 connectors which connect the engine to the ECM. The connectors are located under the intake manifold towards the firewall. You need to remove the battery, pull the connectors apart, give the male side a slight twist, then you add Stabulent 22 to the connectors and reconnect. The dealerships also add some clips to hold the connectors together better. This task is not an easy one due to the location of the connector. I have done it many times in the past and this helped many of my costomers. Anither thing to check is the continuity to ground at the MAF. This also can indicate bad connection throughout the engine harness. to upgrade this connection, clean the ground connections at the battery and under the battery tray. these simple uperations should have been made into normal maintenance for the 95 - 99 Sportages.

You can go to the dealer and have them help you get the code for the radio, if there going to charge you a crazy amount you can try www.radio-code.com. There cost is cheaper and can help you reprogram the code in your KIA. befor you go through all that, check for the code in the glove box, there might be a sticker in there or in your back pages to your manuel.
Good luck and hope this helps yougte your radio wokring again, keep me posted oh and try 0000 first.

Look on the shifter lever,just bellow the push button. There is another push button there. That's the one you press or depress to keep the transmission on 3rd. gear. Just press it again and the hold light should come off.
There will likely be no noticeable symptoms along with this code other than the MIL (Malfunction Indicator Lamp), commonly known as Check Engine Light illumination. However, there may be noticeable fuel odors in some cases.
