Hey everyone.
I have the check system message for my TPMS showing up on my dash ever since I've bought the car from the previous owner. I finally got around to check which exact sensor is the one causing trouble by running a health check on Techstream. The health check resulted in showing me this code: C2126 "Transmitter ID not Received (MAIN)".
What exactly is the issue here? Is it the TPMS Module that is faulty or something else like the sensors in tyres are the issue?

 

The non-replaceable batteries in the TPMS sensors in the wheels only last about 10 years. You didn't list the model year of your car in your post or your profile, but it is most likely to be the problem.

If you have a good tire shop with a handheld TPMS tool, they can tell you which wheel or wheels have bad sensors, but most people just replace all four as a set.

 

I have a 2008 IS250. I do understand the whole deal with TPMS but the error code for sensors are different where it is stated ID1, ID2 etc. The confusion here is the code I got did not specify any ID number.

 

Hahaha! last week my TPMS light went on and the pressure is fine in all the tires. Mine is a 2010, hit the road in 2009 and I read the batteries were rated between 5-10 yrs
Anybody have a PN and link to OEM sensors? I might be buying 4 more, smh

I assume it is also a common part across the 250, 350, and C models, as I drive a 350C (lol yes they do exist)
