My '05 KIA sportage stalls after it warms up , I replaced the idle control valve but it still does it . What is the fix ?

SOURCE: 2000 kia sportage ex, 4 cyl.

Yes there is a sensor that controls Fuel/air ratio.It's called a MAF (mass air flow sensor)
But I think you should have the EGR (Exhaust gas recirculation)valve checked
and The TPS (throttle position sensor)maybe dirty.

Although may things can cause this issue,I would look at the items above first.


Please rate this a blue fixya

Spluttering and missing is usually one of two things Fuel or spark ?
Fuel problems will be traced to 1/ in line fuel filters .. 2/ tank run low on petrol throwing dirt and grit into tank filter ( if Fitted ) and blocked or restricted injectors a good fuel additve sometimes cures that problem , but replacement is a far better option .
Poor spark plugs breaking down under preassure oiled plugs due to overfilling or incorrect fuel mixtures .. poor or cracked distributor caps dirty or damaged rotor arms in said cap .. leaking HT leads damaged by rubbing and contact with hot engine causing sparks to fly to nearest earth disrupting the spark and ignition timing ... hope this helps Regards vortash

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)

You could try replacing the idle air control valve but I would obtain one from a local salvage yard, its cheaper and you are not certain if thats the problem, another thing i would check is your intake manifold gasket where it meets the cylinder head, if tha gasket is cracked or leaking it will allow excess air to enter the engine and make it idle higher, the easiest way to verify this is get a can of carb and choke cleaner and spray it all around the intake gasket area, if the engines idling characteristics change drastically then the gasket is bad and needs to be replaced if theres no change in the idle I would start looking for vacumm leaks and the idle control valve issue, which you specified.

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 !
