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

Application was 2010 Camry. I had a local tire shop mount tires I bought from them, but I supplied the TPMS. If you buy the TPMS from these particular guys, its basically like buying another set of tires. They each were north of $100.00 installed. Buy supplying these to the shop I saved a lot of dough. While these are preprogrammed in the factory, there are still a few registration steps the tire guys have to do to get the car's computer to recognize the TPMS units. My registration went off without a hitch.

Took some time to finally get my TPMS flashing error light turned off, but here is what caused it and how to fix:1) Caused by a low battery on one of the TPMS sensors. Get 4 new ones! You only want to do this one time, why bother trying to find the 1 that went bad, my OEM sensors lasted 14 years before I had to deal with this issue. These Denso OEM TPMS from Amazon are a great price (read reviews about counterfeit units not having a raised/embossed QR code. The ones sold from Amazon are legit, new design with the cloudy epoxy visible on the back. Take pictures of their id numbers before installation!2) America's Tire Company installed them for $20 a tire and verified they could read their ID from the handheld scanner prior and after installation.3) Once installed, there are ways to wake up or activate these sensors either by draining the air on each of your tires to 20psi and then quickly back up to operating pressure or using a handheld TPMS tool. I drained each tire down to 20psi and then filled them back up one by one first.4) Then I loaded up Techstream software with the Car ignition mode or engine on. Connect to your vehicle with your $40 mini OBD connector, see youtube for info on this process and software installation. Select TPMS and then Utility on Techstream, then go through the ID registration process for the "Main" selection in techstream for each of the sensors, the ID numbers are 7 letters/number combos on the sensor. There is a 5 minute countdown timer in techstream.5) Here is the trick: Assuming you don't have another set of 4 tires that you swap in the winter or for whatever with a different set of TPMS sensors, program these same new ID numbers in techstream for the "2nd" selection of tires in techstream.6) Now go back into techstream, TPMS section, select "Data list." You can then view a live table to verify your TPMS id codes have been registered and their tire inflation pressure. It may take a few minutes for the pressure to display, but if the IDs registered were correct you will begin to see the inflation pressure value in the techstream table.7) Now to get rid of that pesky Check Tire dash light on your car. Read Console Codes in Techstream. If you get a C2126 (Transmitter ID not received (Main) code, verify you can read the IDs and the tire pressure in the live Data option of techstream, if the ID is incorrect you won't be able to see the tire pressure and it will throw this code out. IF you get code C2127 (Transmitter ID not received (2nd) code, the trick is assuming you completed item #5 like I outlined above, you need to select the tire pressure display setting on your car's indicator display screen that is above your steering wheel. The way to select it is using the left/right rocker button that is to the left of your steering wheel with the round center select button. Now go to Select Tire push the center button to select "2nd" and then go to the Tire Pressure Set Initial Option, and push the center button. Look back on your computer screen and you should see the live techstream window also show the "Initilization Switch" go to Value "On". Do the same for "Main" for good measure. After doing that my pesky Check TPMS error light went away immediately and techstream didn't pull any more of the C2127 trouble code for the missing "2nd" set of tires registration IDs.A little tricky and some hoops to jump through but you will save a lot of $$$ if you can pull this off!Some cars may have a sensor in the full size spare tire, don't forget about that. Mine does not.

Brought to discount tires, programmed for my car, car relearned the TPMS easily. Perfect for the 2008 FJ cruiser.

My TPMS light had been on a couple of years and was getting tired of looking at it, the dealer wanted $$ to replace them. Watched a few YouTube videos prior to changing my sensors as 2 failed and wanted to try it myself. If you break the bead on one side the tire will not need to be rebalanced. The Denso sensor is only about 1 gram difference in weight so should not affect the tire balance. You will need a programmer to complete the job Such as the Autel 501 as the new sensors will need to be written to the cars computer system. The programmer was the most expensive part but will have the tool for future use. Be safe and take your time and do your research. If doing it yourself is too much, have a good tire shop install them and program them for you. I did not have to fill up my tire and let air out as others reported to wake up the sensor. The tool detected them before I put air in the tires.UPDATE - FAILED AFTER ONLY 3 MONTHS! 10/22I am updating my review, these worked great for about 3 months, then suddenly failed! TPMS light on again!. I originally replaced two of them. One now has a dead battery as my reader shows it very low and the other one will not read at all and assume it is dead too. I purchased one replacement but the tool read it initially but when I went to install it, the new one would not read at all. Not wanting to go through the whole process again will return for a refund. I think if you are lucky and get a good one they are great but would think twice before ordering. Adding a do not buy recommendation now as there appears to be no support for this product, Denso website is useless you can only leave a message and hope they get back to you. One other note, I ordered a whole non OEM set for the price of one of these and they worked right out of the box no issues at all. I would defiantly stay away from DENSO as appears that they are selling returns or old stock- why would a 7 year sensor go dead after 3 months and a second one will not read at all. I am familiar with the activation process, and these both failed after we had some cooler fall weather.LAST UPDATE 10/11, Denso got back to me to say sorry Amazon is not an authorized distributor and no warrantee for the product i purchased --Good luck? I have never left negative feedback, but this is unacceptable DO NOT BUY!

These worked great as an additional set of TPS sensors for a Toyota 4Runner that has Summer and Winter tires mounted of different rims. You will need a tool to tell the car which set of tires is currently on the car when changing sets of tires. It's a quick changeover when using a tool like this. I use an inexpensive tool called AT Quickset.

These were the correct 20° sensors for my 2006 Toyota Tundra DC SR5 4X4 with alloy wheels and a steel spare. This truck has one in the spare.Check to see if your vehicle requires one in the spare. If it does you need to have a working one or the light won’t reset.There’s lots of confusion as to whether this fits a steel wheel. I included a picture of my steel spare and this is the correct sensor.There is also a 40° (550-0102) but that seems to go into the styled steel wheels that would come on the vehicle instead of the alloys.These are at a great price, have the raised/embossed QR code and seem to be legit.The complaints seem to come from buyers that purchased from a 3rd party seller. The seller for these was Amazon and there weren’t any other sellers at the time so I felt confident about the purchase.
