Help with new TPMS sensors

2006 Tundra SR5, 4WD. Original TPSM sensors. Light just came on. All 5 pressures good.
They lasted a long time.
I'm getting new tires and want to replace all 5 sensors.
I'm going with the

$36 Denso 550-0103 TPMS 315-MHZ Sensor for Toyota/Lexus with Factory Alloy Wheel Options. (THIS SENSOR MUST BE PROGRAMMED BEFORE USE)

Denso 550-0103 20° sensors for the 4 alloy wheels.
I have a steel spare and don't know if it takes the 550-0103 (20°) sensor or the 550-0102 (40°) sensor. I need to have them when I take it to the shop.
Thanks!

 

Someone with a first gen should chime in, but generally there are two sensors, one for the alloys and one for steel. If you have confirmed 5500103 is for alloy wheels, then the other unit is for the steel wheels. They are not interchangeable.

This may help, input your truck details and vin and it should specify the parts

I saw this on another post so I don't know which one I need. Should I assume the spare is a standard steel wheel?
1) Style Steel Wheel uses 40° TPMS sensor
2) Standard Steel Wheel uses 20° TPMS sensor

 

The spare should be a standard steel wheel.

Not sure what size your alloy wheels are, mine are 20", but my steel spare is 18".
Keep that in mind when buying tires..

Although I'm pretty sure they were all 18 on my 2005.

Welcome to the forum..

 

All wheels are 17".
Thanks.

 

I'm just going to assume all 5 wheels take the 20° sensor. I'll update when complete.

 

I thought I'd update.

Denso 550-0103 20° sensors for the 4 alloy wheels and the steel spare. That was the correct one for the spare.
They look like the OEM except for a different designed back. Light reset after the ID's were entered into the ECU.

 

Have a 2016 Tundra SR5 that came new with Toyota 20 inch Rims with BF Goodrich AT 275/55/R20 LT mounted on them. The Tire Inflation decal on the inside of the Drivers door frame gives a pressure or 49 psi for both front and rear. This is quite a difference from the 35 to 40 psi I see folks posting on here for their tundra pressures.

Having 97K on the original tires and the PVD coated Rims being eaten alive by Winter road salt, I have replaced the Rims with custom 20 inch rims, and up sized the Tires to 285/60/R20 BF Goodrich LT AT Tires. Ordered OEM TPSM Sensors, installed them, and have tried ReLearning the new 1's with an added tool I bought, and tried the Owners Manual procedures, of which none work. Indications on my dash are that the who system is inoperative.

Spent 30 minutes today talking to my local Toyota Dealership Maintenance Dept. who informed me that Yeah, the system is a bitch to set up for the uninitiated, and straight out of the box with a "supposed" set of 4 TPMS sensors. He also told me that sensors generally have a service life of 50K to 150K miles, and as I 1/2 way'ish, and as I still have the old ones on my still built up Rims and Tires, I asked if i could simply swap the old ones back to the new Rims. Yes, and No. They have to be checked once again after they are removed, and hope that they still function correctly. Am taking it in to the shop in a few days to have a TPMS system check of sensors, remote, and the control unit. That is $150. New Sensors are $250 to $300 to replace and install.

What I have not been able to find out though is if the new OEM sensors I bought, that were ordered for my vehicle year specs, account for the added size in Rims, Tires and PSI's that were added by Toyota as an upgrade to my SR5. Am really trying hard to avoid potentially spending another $500 on getting rid of a "Low Tire Pressure" light on my dashboard when a 1 inch piece of Black masking tape will do the same trick, and I revert to how i used to know if I had a low tire psi pre TPMS, by how it handles, and pulled when breaking.

Anyone else had a problem with replacement "off the shelf" Tundra TPMS sensors who might have an in-sight?
