Did the 2023 not come with factory TPMS ?

 

Yes but I need another set of wheels for winter season.

 

I was under the impression that they use an indirect TPMS, which utilizes the abs system sensor, as opposed to direct which would have a sensor in each tire. That is why it directs you to drive the vehicle when first started before tire pressure can be displayed.
From what I have seen in the past few years most manufacturers have switched to the indirect system.

Did you end up finding a set of winter wheels?

And also interested in whether you applied any sort of undercoating or rustproofing to the undercarriage?

 

Only got 4 mag wheels 18 inch.. still waiting for TPMS and winter tire. Nope I will keep it only the coverage of the warranty but pretty sure it should worth the money if you want to keep it longer.

 

The sensors should be 433MHz in wheel ones. Many tire shops use universal Autel sensors, so do I as they are dual freq and can go on and be programmed to any car.

 

We just swapped to our winters on steelies, no TPMS, and the car "re-learned" the tire pressure and the light went off after driving it 5km. 2022 Sportage PHEV (Canada).

 

Thanks for the data point. When you say "no TPMS" do you mean that you omitted putting TPMS sensors in each of the winter wheels? If so, how did it re-learn the tire pressure... maybe using indirect TPMS?

 

I'd assume indirect yes, I declined the extra $$$ for TPMS in the 4 winters because I was very angry at the Kia stealership but that's a story for another day (never go to Nanaimo Kia) so I was expecting to have the light on all winter, which personally, I was okay with, but I know some would disagree. Anyways, was pleasantly surprised that they were not required, and the car figured itself out.

 

I think the tire pressure is calculated with some kind of algorithm/equation from ABS sensor value.

 

I got snow tires via TireRack for my 2023 Sportage PHEV X-Line Prestige USA. The phone salespeople had a bit of trouble inputting the car correctly (selecting Hybrid instead of PHEV, make sure to check an email quote before preceding over the phone). The TPMS sensors were actually different based on what version of the Sportage was selected. Installed the mounted tires at home and after a few minutes of the driving the car recognized the tire pressure in all four tires. No need to reprogram car. The part numbers that TireRack provided in the invoice were S190-MOD / 5523-TR with a name of "CONTINENTAL 433MHZ SENSOR 8 NM REPLACEABLE VALVE 8NM=71IN.LB" at a price of $50 each.

According to this reddit thread, the Kia part number for the OEM TPMS sensor is 52940L1100 for 1 sensor or Q5H40AK000 for a set of 4 sensors. Although based on my experience, the OEM sensor is not necessary for the car to learn the connection.

 

Yup those are the TPMS sensors I ordered for my winter tires as well.

 

What Koreanadian said -

I don’t believe TPMS sensors are needed in the tire valves. Period. The ABS computer “senses” the rotation radius to gauge tire pressure. Doesn’t hurt anything to have them, but they aren’t even used, so a waste of money.

And just like viisory said, no TPMS sensors found in the wheels when he had the tires replaced.

Obviously, even the Kia dealers haven’t gotten this memo and are happy to sell you unneeded parts.

Anyone else here had tires replaced on the stock wheels and can confirm?

A tire pressure light never came on in my case. I do think my car detected the new TPMS sensors rather than switching to an indirect measurement.

I'm no expert but I imagine indirect measurement is less accurate than direct measurement and has a larger surface of failure or inaccuracy modes.

 

Finally got 4 TPMS sensors PN 52940l1100 for my winter wheels and after 5-10km it been detect by itself without a tool or something to do.

 

So. I don't believe that my 23 Sportage EX HEV doesn't need TPMS sensors to not have the warning light/message on the dash.
I have Winter tires on a set of 17" wheels from a '16 Sportage. The wheels have OEM '16 Sportage TPMS sensors in them, I think they are 333Mhz.
So if the theory that no sensors are needed to not show a warning light is valid, then my wrong frequency sensor wheels, should Not have a TPMS warning light.
But I do!

 

But, your winter wheel/tire combination may have a slightly different circumference than stock?…May only take a ABS system reset to get that new distance “memorized”.

 

I questioned this at the local Kia service department. I know in general sensors are designed to go into sleep mode to preserve battery life until a signal from the system or rotation activates the sensor.
I asked the Kia service manager if they used sensors in the wheel or the ABS for tire pressure. I was curious as it acted like ABS due to having to drive it before it would show pressure. He told me that it was still using a sensor in the tire, and rotation wakes the sensor.
I used to help my friend at his service station until he sold it. I took care of setting up new sensors in the cars with his TPMS tool. I actually never had the opportunity to work on a Kia. I know older Japanese designed cars used rotation or RF signal to wake up sensors, and need a TPMS tool to re-program for new sensors to work, while newer ones have switched to ABS. American designed cars can learn to recognize new sensors without a TPMS tool. Perhaps Korean cars are like American.

I think your instinct and logic are spot on. My experience is that dealerships often have no clue about what tech is in these new models. And if TPMS sensors were actually required, how does this explain viisory's experience w/new winter tires & wheels (no TPMS sensors installed) detailed above?...

And you can add VW/Audi to the TPMS-less car manufacturers. Our new GTI doesn't have TPMS sensors either.

One other data point - Our older Volvo that definitely uses TPMS sensors (because I had to replace them), shows any tire pressure issues w/the spare tire, too. There is no spare tire pressure info showing up for our Sportage HEV.
