TPMS for 2012 and 2013

I finally found a really nice 2012 TRD Off Road Access Cab this week. I have a 2013 SR5 Access Cab 4X4 with the third generation TRD wheels and tires. Those wheels have the original TPMS from the original 2013 wheels. I switched the tires and wheels with the 2012 now having the TRD wheels with the 2013 TPMS. After about 20 miles the tire pressure warning light came on. The light has not come on in the 2013 with the 2012 tires and wheels. Rock Auto shows the same part number for both years.
How do I get the warning light to turn off short of having the sensors moved?

 

You need to have the new sensors programmed to the truck.

 

^exactly^ Most tire shops will do it for free.

 

I haven't had the need to yet, so have not tried them myself, but you can also get programmable sensors so that the existing ID numbers can be cloned to the new sensors and avoiding the need to program the IDs into the ECU. I'm also not sure if Tacos require the IDs to be programmed into the ECU or not, or if it is a "passive" system that can use any correct sensor. For example, in my wife's Prius, the IDs have to be hard coded into the ECU, but my daughter's Versa will just pick up whatever sensors are there once you initiate the relearn.

 

Thanks. I will check with the tire shop I use.

 

The 2013 sensors are 9 years old. Typical life is 7-10 years, although it isn't unheard of for them to last longer. There is a good chance they are dead. You should have just bought new sensors when you did the swap.

I had new tires installed about a year ago and took the sensors I ordered with me. There was no charge to install and program them at the same time they were mounting new tires. I was proactive and replaced mine before they went bad. It will cost $10-$15 per tire to have them installed afterward. I knew the old sensors would die before the new tires were worn out.

 

I was unable to break one of the lug nuts loose on the new to me 2012. So I drove it yesterday about 30 miles with that wheel still on the truck. No issues. The tire shop I use got it loose so I switched the last wheel. As soon as I started driving the TP light came on. All 8 tires were set at 33 PSI. I drove the 2013 today about 20 miles and no light. I stopped at the tire shop to see if they have the scanner. Before taking the 2012 to them for scanning I decided to disconnect the battery for a few minutes. When I started the 2012, the TP light was flashing. While resetting the radio presets, I noticed the light was off. Drove it a little and no light.
The 2013 is for sale. I appreciate the information about the life span of the monitors so I will purchase new ones when the tires need to be replaced. It has the Goodyear with Kevlar. Of course sooner if these die or I have the tires broken down at some point.
Again, thanks for the advice.

 

Mine are 10 years old.
No issues...yet.

 

About 10 yearsish is average from what I've heard. If you have a Walmart Tire Center (and trust their tire monkeys), they do TPMS swaps and treat it as a flat repair (so at the one near me, $10 per tire).
