TPMS SENSOR 433HZ

[4cylfukboi]

Hey guys I have read through all of the TPMS threads on this website. I'm just making sure I have the correct information as the ones I ordered I believe won't work.

Our systems operate at 433HZ and we can put in our information and do the relearn VIA iDrive.

Is it safe to say that ANY 433HZ sensor will function the same? I have sensors laying around for another vehicle manufacturer that fit on my wheels that spec say 433 HZ is the active frequency read.

Any input would be greatly appreciated. I'm trying to source sensors this week!!!

Yes.

Much appreciated in the original TPMS thread there seems to be alot of hoopla about NEEDING to buy OEM.

Oreilly stocks them part# 20154 line code SCH.

In this case if NO tpms does does not do anything to the vehicle I likely just won't install them. I just wanted to avoid any issues with speedo, tc, etc. Due to the different sized wheels...

Tpms is strictly for monitoring tire pressure. Tpms stands for tire pressure monitoring system.

Only problem you could have with your speedo is if you have a different outer diameter configuration on your new wheel and tire setup.

The diameter is very different. I was under the impression that the relearn for wheel size etc. Is in the same menu as TPMS..

I actually bought universal sensors. They work.

@nibble this is why I'm confused. Multiple people are experiencing multiple different things..

not sure how much difference between huffington from ebay vs. universal, safe bet is huffington since they supply OEM.

It won't relearn the diameters. TPMS has nothing to do with that. Only tire pressure and temp. If you have smaller or larger diameter than stock, the speedo will be off.

I bought these TPMS, and they work perfectly: https://www.ebay.com/itm/264724886078?hash=item3da2d5323e:g:KkAAAOSwNrBZ-j7e

Thats not the information I was told here that other members seem to agree with.

I bought 433mhz BMW Sensors, and they did not work.

Cool, I can tell you from experience, that is not correct. Speedo will be off. With 295/30/18 tires, my speedo was off by around 10 mph 120mph+. Verified by GPS. The TPMS has nothing to do with it.

Spoiler alert, even 100% stock, the speedo is off from actual reality.
