Leave it installed and use a Live Data Scanner,, see what the ECU is seeing..

Also keep in mind you are resistance testing an unloaded circuit, more often it's not being given a chance to show failure. Supply it 5v and retest may prove more revealing.

Thanks for your suggestion, I will do that. But how do you know that it needs 5 V and not 12 V?

Thanks Philip, but I will remove it to test it in the same conditions of the old one. to see if there is any difference, because I am curious and because my new sensor is giving me more troubles than the old one. For this reason on saturday I will solder its connector electrical wires directly to the TPS contacts, and if in the future I will have to disconnect it I will unscrew it and I will remove the whole sensor. And, since I am there, I will double all the ground wires, always soldering them directly to ground.

Preparing for removing the throttle position sensor connector.

Wires soldered directly on my old TPS contacts. I have used telephone wire

I added heat-shrink tubing. I have not been able to shrink them well by my hair dryer, but I think that they will be shrunk well by the engine compartment heat

Resistance retested

There is a very slight resistance improvement, I think due to the better connections

Maybe just a FLUKE, sorry, could not RESIST...

My old TPS is back on my Sportage, but without its connector, as I soldered its electrical wires directly on its contacts

Today I tested it well and it worked perfectly, although it is still too early to say that for sure.

p0422? I don't know if you have a smoke machine but I would check the charcoal canister. a lot of times the get a leak at the screw holes. id say more than half the time I see that code on any kia its a leak at the canister. definitely shouldn't cause the vehicle to run rough though.

Testing my new TPS

My new TPS

Its resistance between contacts number 2 and 3 goes from 1.087 kΩ

to 3.062 kΩ.

In my opinion both the old and new TPS resistance values would work - the scale of change from min to max is the same.

The ECU will learn what precise value for closed and wide open throttle - make sure you reset the ECU when installing a new TPS.

Yes, I agree.

On Saturday I went on a 75 miles trip with my Sportage, a round trip, which included uphill and downhill of mountains and the car did not show any problem caused by the TPS; moreover at home I tested my new TPS connected with the connector and occasionally it showed some outliers, so, at this point, I am sure that the problem was caused by the connector not enough close contacts.

I had to decide whether to buy a new connector, which is for sale on Rock Auto website for about 9 €, or make the connection without a connector, only by solderings and I have decided to use the solderings, because they provide a permanent solution to the problem, and also because the connector leaves me one more variable to check in case of malfunctions. But, before I can remove the temporary joints that I put, I have to get an heat resistant tubing to put around the sections of electrical cable that I added, then I can solder them definitively.

I might be doing this too. I put a new TPS in last week, and on the way to the highway for our hunting trip, CEL came on:

P0123: Throttle/Pedal Position Sensor/Switch A Circuit High Input

I have ordered this heat resistant tubing, from here, I choosed the 10 mm size, black color; so as soon as I will receive it I will be able to conclude that job.

I am sure that doing that you will solve your Sportage issues, described in your thread, because that solved mine.

You can go by soldering, but it is not easy if you do not have much experience with soldering, in this case I could give you some tips, or you can buy a new connector from Rock Auto. The IAC and the TPS connectors are the same.
