Post subject:  TPMS frequency

I'm looking to buy a set of TPMS sensors for my 2012 KK sport and when I look them up I get options for 315mhz and 433mhz. Is there any way to tell which are the right ones? My KK does not have the premium Tpms if that makes a difference. Thanks!

US/Canada = 315 Mhz.
European and Australian markets are 433 Mhz.

Your welcome.
I have seen some strange things with TPMS, so when you break down the tires make sure you are removing the same frequency sensors.
If there are OEM sensors in the tires currently, and you can not read the frequency, the US sensors have a black sensor body with a grey valve stem cap, export have a grey sensor body and Black valve stem cap.
Not sure why Jeep decided to use opposite cap /sensor body colors...

Thanks for the frequencies! I want to have a second set of offroad steel wheels, and I thought it would be easier just to purchase a second set of TPMS sender/transmitters for the steel wheels rather than steal the current senders from the factory alloys. My car is a 2011 KK Cherokee Limited CRD, Australian delivery. Any way I could look up the actual Jeep part number of my sender without getting one out first?

You're welcome.
There are now 2 variations of the export sensors as well as the US sensors.
Metal stem and rubber stem.
You will need to verify the below because the parts manuals I have are conflicting.
The 11 manual has the below reversed as to which one is metal/rubber when compared to the 2010 parts manual. In 2009 they only show 1 stem option, the metal one 56029465AB.
And in 08 a totally different #.
These are only for the EXPORT 433 Mhz.!
Rubber stem #56029481AA
Metal stem # 56029465AB
Before you purchase, verify the frequency and which stem it has. The metal stem will require a mounting kit (nut, washer, "O" ring) if it does not come with it.

Now, with a set of 4 new sensors, the rig should learn them when you drive above 24 Km/h (15 m.p.h.) for 10 minutes.
But some Euro rigs have had a hard time with this. So you may have to actually have them programmed into the computers. Be sure to write down the sensor IDs for the new ones before you mount them.
You are also limited to, I believe, 10 sensors in the computer system, so if there are already others in there besides what is on your rig currently, they will have to be removed before the new ones can be learned or programmed.

If you try to let them self program, make sure the old sensors are not near the rig, and no other CDJ rig with sensors is around you. Drive above 24 Km/h (15 m.p.h.) for 10 minutes.
If unsuccessful you will have to park, remove the key, and wait 20+ minutes before trying again.
