Forgive a DUMB TPMS Question

My 2012 Reg Cab 4x4 is due for Tires. I decided to upgrade to "new to me 2018 TRD Sport wheels". I got a great deal, and they came complete with TPMS Sensors and original tires. I have new tires on order.

My question: Will my 2012 Tacoma understand the sensors in the 2018 rims? Or do I need to move the original ones over?


Thanks in advance for the help.

Good question. I was able to reuse the ones from my ‘14 on a set of ‘18 4Runner wheels l bought. Worked flawlessly.

 

as I understand the systems, no
3rd gen trucks uses a newer version of the system that transmits more data differently
that's why 2nd gen basically have an idiot light and 3rd gen has pressure and temp for each wheel

 

I believe your truck can read the 2018 sensors but you need Techstream to program the 2018 tpms serial #s into the ecu. This may be your best option since tpms batteries normally last 10-12 years.

 

The second gen Tacoma sensors also send individual wheel pressure and temperature data, but because of the cheap implementation the trucks can't display it. 2nd genners can access that data with a ScanGauge 2 or similar. So, the sensors are probably the same.

 

Your 2012 TPMS sensors are 10 YO. The batteries are probably on their last legs.

 

I tried some secondhand 2020 4Runner wheels on mine and could never successfully get the receiver to read. Each sensor was reading and I programmed the IDs to the truck but couldn't ever get them to talk to each other.

 

3rd gen TPMS sensors do not work for 2nd gen. They operate on a different MHz frequency. You need to move over your 2nd gen sensors (which mentioned above are 10 years old so probably best to buy new ones so you don't have to do it twice).

 

Thanks to all that responded. Based on the feedback, I’m going to buy 4 new sensors. At ten years old it doesn’t make sense to move the existing units over.

 

Yep, smart thinking!
