I am hoping to get some guidance or advice on an issue I just ran into.

I just got a set of new Pacific PVM 107J TPMS sensors for a new set of wheels on my LS460. I opted to reuse the sensor for the spare. I registered the 5 ID's using Techstream into the ECU.

All 5 codes were registered and I saw that 4 of them displayed pressures and temperatures (3 Pacific and the spare). Only one was N/A which led me to believe that one of the Pacific sensors was faulty.

I drove the car for about 5 miles to pick up some stuff at the store. Returning home, I decided to use Techstream to pull the code again. Now it is showing that all 4 Pacific sensors are no longer registering pressure or temperatures, only the sensor in the spare wheel is registered a pressure. It is showing me code 2126 (Transmitter ID not received in Main mode).

Before, when I didn't have the ID's registered, it would throw 4 different codes for the missing sensors ID#2-ID#4, but now I only get code C2126. I've tried clearing the DTC, but it comes back immediately.

Does anyone know what a possible solution or what the problem is? I'm stumped at the moment...

It was plausible that 1 out of my 4 sensors could have gone bad, but now all 4 going bad? I suspect that something else is wrong or I may have done something incorrectly. I've been driving on these sensors for about 50 miles before I registered them into the ECU.

**EDIT** for whatever reason everything is working perfectly today....

 

Weird issue, however TPMS systems can be a handful at times.

Curious to see if the problem ever came back.

 

Hasn't come back. Sys has been working perfectly.

 

I had same issue "c2126 & C2127

" I sort it out yesterday by using TIS Techstream i found tpms id 4 not working so i change it and i registered tpms main and 2nd by using same tpms id and the light goes off


i hope my reply is helpful if not please feel free to contact me
