So I've been looking at TPMS sensors for a set of winter wheels. There appear to be 2 distinct tiers of TPMS sensors - OE or OE Replacement (~$75-90 each) and Universal (~$40 each). Huf makes both in 433, but says that the Intellisens needs to be "coded". VDO / Continental also makes a both types of sensors.

So... here are my questions...

Does anyone have any experience with the Universal sensors? Any thoughts on them? Do they really need to be coded?

At the end of the day - will any 433 sensor work right out of the box?

I'm having a hard time justifying 2x the price for a sensor. I'm also having a hard time with $75 for a sensor when the rims are less than $200 each. It's a consumable for crying out loud. I don't need to be rolling on $2500 set up.

Thoughts?

And, before you flame on me for not searching - I did search a couple of ways. There isn't a lot on TPMS, other than a few other questions and a couple peoples experience (one on Audi OE, another on some other brand I've never seen).

Thanks!

You might take a look at this thread:

The answer to this question is definitely "No". The entire TPMS system has to be talking the same language and not just operating on the same frequency.

The correct Huf sensors for 2011-2014 are tirerack.com part number RDE011. Should run about $250 for a set of 4 including valves, stems, caps, and the sensors.

Thx Gents. Anyone have any insight or thoughts on the "programmable / universal" sensors? Huf's own site says the UVS2000 and UVS02C4V21 "universal" sensors will work (with programming), while the RDE011V21 is Direct Fit. I'd certainly be interested at $40 per instead of $75.....

Take a look at Schrader's new EZ sensor. They will program to 90% or better of all cars and trucks. Costco has the tools, Bartec Pro 400 or 500. Very easy to do.

OEM price is crazy since the battery will only last 2 - 3 years.

Look at this from a local supplier 4 sensors with rechargeable lithium batteries with readout.
tpms-prestige.PNG

that's aussie dollars so about half that for you Yanks!

why aren't these things powered by peizo or something which is powered by the spinning wheel?

The sensors send pressure and temperature readings to the monitor every 5 minutes. If any reading is out of the pre-defined values, you will notice (1) An audible alarm (2) The red light on the monitor will flash (3) The corresponding icons on the monitor will flash.

TYPE OF ALERTS INDICATION:
1. High pressure alert.
2. Low pressure alert.
3. High temperature alert.
4. Fast leakage alert.
5. Sensor low battery alert.

Monitor Features:
1. Reliable and easy to install.
2. Built-in rechargeable lithium battery.
3. Automatic backlight.
4. Automatically wakes when vehicle start moving.
5. Configurable high/low pressure warnings.
6. Configurable high temperature warnings.
7. Visible and audible alerts.
8. Selectable pressure units: PSI or BAR.
9. Selectable temperature units: °C or °F.
10. Monitors up to 5 tires maximum.
11. Display pressure or temperature of 4 tyres simultaneously.

5 minutes can be a very long time in the event of a puncture . . .

Bit off track, but I purchased and installed a set of these:
Steelmate Australia & NZ- TPMS, Parking Sensor Specialist
They work very well I think, depends on your preference for internal or external mounted sensors. good thing about these is ease of install and simple replacement battery process, negatives: ease of uninstall (theft) with little tool and the fact that they mount on the outside on top of valve. I haven't had them long enough to note battery duration, but they pick up changes in pressure very well.

Maybe 5 minutes is. But if a blowout occured i would think it would be noticed. Tubeless tyres usually go down slowly unless the the cause is catastrophic failure. However i was more trying to highlight the price... and why are they not self powered?

B -

I can safely say without a doubt that any 433 MHz sensor will not work. From what I've found out is that there are about 17 different versions of the 433 MHz sensor, according to my independent mechanic. I purchased some cheapy ones off of eBay that had a ton of "positive ratings." The sensors were fine for a few days, and then the TPMS alert came on. Seller told me to try setting them up again, which I did, but still do no avail. After going back and forth with the seller, he clearly didn't know his product. Needless to say, I've still got sensors that constantly go off and on that I've just decided to ignore. But once I replace the tires, I'll be getting some different sensors - from a reputable dealer.

Do you realize the headaches you may incur by "cheating out" for a part which will last 7 years? I would say see the previous part number and buy OEM
