TPMS

I bought some ‘16 TRD 18” alloy wheels to replace the steel on my ‘19 SR. It appears the ‘16 uses a different sensor to the ‘19. The ‘16 sensor can’t be programmed to my ‘19 either.

Argh

Anyone have an easy fix or am I gonna be selling a set of ‘16 wheels

 

Buy new sensors
I have a set for sell

 

I believe the TPMS can be turned off. I believe it requires access to the Techstream software. That would be my solution: shit can the stupid TPMS itself.

 

More than happy to, but the shops saying they can’t program the 16 sensors to the 19 truck.

 

Now that’s a plan. Technology can be a pain

 

2018-19 trucks use a different sensor and Toyota has two different sensor types-steel wheel and alloy wheel.

So if you buy some 2018+ Alloy sensors to use in those new wheels you’ll be set.


You can buy OEM or aftermarket sensors


I recently used these and have no issues. They came pre programmed and followed the directions in manual to have truck read new sensor signals.

The shop manager got involved and figured out a soloution. He went old school and used a band to hold the Sendor and fitted regular valve stems. Did 300 miles afterwards and it’s working great. I need to get the alloy wheel sensors but this fix will last till I replace the tires

 

So with these itm sensors, would I need to have them registered to my truck? Please pardon my ignorance, I bought some rims and tires without doing my research on the tpms and I have a 2018.. now I’m playing catch-up and it’s getting to become troublesome for me.

 

Which year sensors and how much

 

The itm came preprogrammed to work in 2018+ tundra.

Shop tried to make me pay 75 calibration fee but told them I didn’t need it.

The truck can register them via the manual instructions.

They didn’t know what they were talking about and said it wouldn’t work.

5 minutes after leaving I did the process and they been reading signal since.

 

So all I have to do is have a tire shop install the itm sensors, then balance the wheels and I’m all set correct? Just wanting to be sure.. I’ve had the biggest stress ever switching from my Steelies over to then limited wheels.. first it was the lugnuts... the the lugnuts being 21 millimeters instead of 22... then the tires were a tad too big, then the tpms.. then this then that omg what a headache.

 

Danny,
There’s a process for resetting the TPMS. It’s simple, pushing a button on your dash. Look in your owners manual.
You should do this as soon as you leave the tire shop.

 

I have both the set of sensors and the fit kits that allow you to install the the sensors, 200$ for both the sensors and fit kits. Call me 2288065536. I have done this many times

 

Will I need the fit kit with these

 

I highly recommend a new fit kit with any new sensor. Better to be safe. The fit kit hold the sensor in place and seals it. If you have existing sensors the old fit kits will work but I am basically tossing in new oem kits for free

 

Anyone know if the 2020 is same as the 2018-19 TPMS System.
I have a 2020 Tundra recently bought a wheel and tire pkg with TPMS sensors included pre-programed for a 2019 since they said there was no protocol info out yet on the 2020s.
I have an

$199 Autel TS501 TPMS Programming Tool, 2024 TPMS Relearn Tool Upgraded of TS408 TS401, Activate/Relearn All Known TPMS Sensors, Program Autel MX-Sensors (315/ 433MHz), TPMS Reset/Diagnosis

Autel TS501 which can relearn the sensors to the vehicle via the OBD port.

First try after putting the new wheels on, I was not able to read any of the sensors, in fairness I had not updated my TS501 since early 2018 and it was only showing me a programing option for 2017 model Tundra's. I completed the latest update yesterday and got it to where I can select a 2019 model Tundra, and it worked great, read all the sensors instantly, I recorded them all and followed the instructions, I was successful at getting the new sensor codes stored in the trucks computer. I have driven it several times repeated the whole relearn procedures several times, still have the light on the dash, and none of the tires are showing in my display. I read the manual tried the relearn procedure, via the button on the dash, still could not get them to read. This morning I dropped all the pressure down to within 5psi of the door sticker. Repeated the process again drove it 20 miles, still no change, light is on the display has 4 blanks.

Now my Autel TS501 use to ask me if I was programming 4 or 5 tires to a vehicle. Now it does not ask that nor offers me a choice to change it. It shows no data recorded or essentially an error for the spare. My Tundra manual indicates the spare does not have a sensor, nor can I pickup a signal from the spare, nor does the display screen on the truck indicate a spare tire pressure. So I am assuming the spare tire does not have a sensor and should not be creating any problems here. ????

Toyota's TPMS is always giving me fits. Any help would be greatly appreciated.

Thank you.

 

I doubt they would have changed anything to make the 19 sensors incompatible with a 20.
What I would do is remove the negative battery cable for a few mins to reset the ECM. Then try again to write the new sensors to the ECM.

The TPMS button on the dash is only to be used when the TPMS system is otherwise working properly. It’s only there to reset the baseline air pressure.

I’ve never seen a tundra with a sensor in the spare so I wouldn’t be concerned about that.

 

Thanks.
I spoke with Autel tech support this morning, since the tool use to ask if I was wanting to setup 4 or 5 sensors. Now after the last couple updates it no longer ask that just tries to get a reading for the spare/5th sensor. They told me to hit the No key when it ask for that spare sensor, that was likely my problem, then it would pop up an X for the spare on the tool's screen it did I tried it.

I then repeated the process. They also told me as soon as I had completed the process to hit that relearn button the truck and go drive it 20 miles.
I have now done that process twice, still no effect.
The truck's Computer has the correct codes in it for the new sensors, I have read the codes stored in the truck and compared them a dozen times now. They match.

There is a TPMS DTC code C2126 (transmitter ID not received (main) . Normally I when I tell my

$199 TS501 TPMS Programming Tool, 2024 TPMS Relearn Tool Upgraded of TS408 TS401, Activate/Relearn All Known TPMS Sensors, Program Autel MX-Sensors (315/ 433MHz), TPMS Reset/Diagnosis

TS501 to clear those trouble codes it does and that light will go out at least for a short period, till it faults again. So far it's not allowing me to clear that C2126 code. I have tried clearing it multiple times and can't get the TPMS light to go out.

Is there any details or definitions available on what a blinking TPMS light means vs a solid TPMS light?

 

I'll speak to what I learnt when i switched wheels. Have both the 18 steelies and alloys with their own TPMS. Followed the procedure in the manual and it took a lot longer to register than what the manual said. I think mine took about 2-3 trips of varying speeds for it to register.
During the learning process, the TPMS symbol was blinking so I think it indicates that the ECU is learning.
When the TPMS symbol is solid, I believe it indicates that there is an issue and needs attention. I was on a trail and had to air down the tires to around 22psi. The TPMS symbol was lit solid and in the TPMS screen, the psi display for each wheel was flashing.

 

Update:
Paid the local dealer $50 bucks to try and program my 2019 sensors to my 2020.
No luck, still didn't get it programmed, but I know now what the issue is. I am told the issue is there is a new sensor for 2020s only on the Tundra's with smart key option.
Since my Platinum does now have the smart key. These 2019 sensors will not work.

Since there wasn't a smart key system available on the 2019s at all none of the aftermarket nor factory sensors for 2019s will work on a smart key equipped 2020.
So in my case these 2019 sensors will never work in this 2020.

 

2020 TPMS with smart Key Update number 2:
OEM sensors are back on the truck now in the custom wheels. The self learn feature worked just fine. Put it in learn mode and it picked up the original TPMS sensors and stored them. No real need to even have a TPMS tool to program a 2018-2020 assuming you have the correct sensors in it. LOL

Learned another thing about the 2020 with smart key TPMS sensors. In order to read them I had tell my TPMS tool that I was scanning sensors for 2019 Land Cruiser. When trying to scan them for a 2019 Tundra got nothing. Which sense the 200 Land Cruiser has always had the smart key system, I thought I would give it a try and sure enough it read the 2020 smart key optioned sensors. I am not sure if I could have complete the programing since I was telling the TPMS tool that I was working on a 2019 Land Cruiser. I decided to give the self learning system a try and it worked so I called it good at that point.

 

Thats what I discovered when I switched wheels on my 2018. The TPMS ID learning procedure as stated in the manual works for getting the TPMS IDs registered in the ECU without the use of the techstream tool. It just took a little longer than I had anticipated.
