TPMS light blinking
I purchased a set of 20" SRT rims from a previous Jeep WK owner and he had the sensors in the wheels already. I put them on my Jeep last night and now the light blinks for a few seconds and goes off, then comes on again some time later. I've read that this indicates a problem with the system, but how can I fix this? From what I've read the sensors should match up automatically. Maybe I haven't drive long enough (~45 minutes) for that to take place? Is there a way to reset the system without taking it the stealership?

Re: TPMS light blinking
What year are the SRT rims?

There are 2 different frequencies used depending on the year. You have the wrong sensors in your rims. You need 06 ones as your Jeep in an 06.


The TPM system operates on either a 315MHz radio frequency (2005-2007 Grand Cherokee) or a 433MHz frequency (2008-2009 Grand Cherokee). All 2005-2009 export models use 433MHz. Starting with the 2008 model year, many domestic vehicles switched to the 433MHz frequency. These vehicles are the Grand Cherokee, Commander, 300C, Charger, Challenger, minivans, and the new 2009 Journey. The 315MHz sensors will not work in the 433MHz system, and will cause a system malfunction warning in the Tire Pressure Monitoring System. Also, the dealer TPM/RKE Analyzer tool will not read the sensors if set to the improper year. It is very important to be sure to use the correct part number when replacing sensors, and to set the TPM/RKE Analyzer tool to the proper vehicle and model year.

The guy I purchased them from had an '05 Jeep Laredo 3.7L, I have the same but an '06. He didn't have any problems with them.

Re: TPMS light blinking
Maybe you could try driving for awhile longer or maybe you have a late 06 model and they changed the frequency

Re: TPMS light blinking
I had the same thing happen on my srt wheels and it turned out that one of the sensors broke off inside the wheel

Thanks for all the post guys, turns out I just needed to drive it a little longer. The light is gone now.
