Denso Tire Pressure Monitoring System (TPMS) Sensor - 550-0103 (Fits Select Models and Years of Lexus, Pontiac, Scion, and Toyota Vehicles)

I installed 5 of these with my new tires on my 2009 Lexus RX350. I use an Autel MaxiTPMS TS501 tool to scan the codes and upload into the car's ECN with the cable that's included with the tool. All good. This is a great tool. The tricky parts: 1) be sure and wake all the sensors up. On the first pass, I don't think I did, because two were not responding to the TS501 trigger. The would sit there for a long time, and then finally pop up with a "duplicate" ID message. They were obviously communicating with another sensor somewhere else on the car. So I went back and deflated the tires quickly (unscrewed the valve core) to <20psi, and then reinflated them to 33 psi. I then cleared the codes in the TS501 and started over. 2) upload the codes to the ECN, and be sure to check "TPMS Status" with the tool. If not all sensors show a response and a connection (indicated with icons on the status output), click on "repair" and let it go through it again.... Everything cleared after this step for me. 3) Though the codes in the car's ECN now matched the codes scanned by the TS501, my dash light was still flashing. This happened 3 years ago when I first replaced sensors when installing new summer tires. The solution (worked for me at least) was to hook my laptop up to the OBD-II port and connect TechStream. Go the the TPMS table in TechStream and check (again) the codes. Once in TechStream, after a short while, the light went out. Exactly as it did in 2019 for me. I didn't change anything through TechStream, it seems that just by going into TechStream the ECN gets the word to start behaving. Maybe a ploy to get owners to have to go to the dealer to buy sensors and maybe even tires? Anyway, all is well now for me for another 3 or 4 years.

TPMS Amazon review I write this review to try and clear up some of the timidness I had when purchasing these sensors. I’ll admit, I wasn’t sure if I could get these sensors to work using the tools I had when I ordered them. In short, THEY WORKED. I installed these on a 2008 Scion tC with 168k+ miles and was able to wake them up and write them to the ECU using an Autel TS601. In theory, you should also be able to use the Autel TS501 as well since it has the capability to write the new sensor IDs to the ECU as well. There is a review by Paul on March 8, 2019 that describes the authenticity of these sensors. When I took out the stock sensors, they also had “Pacific” on them. The tC uses a low profile tire and since mine were worn out and I don’t have a tire changing setup, instead of breaking the bead I did the “easy” method and cut a hole in the sidewall big enough for my hand and replaced each sensor. I also torqued them to the required value printed on the sensor (4 N-m). I believe it was an 8mm socket. With the sensor replaced, I took the wheels (off the car) to Discount Tire to replace the tires. Once I picked them up, I put them back on the car. There is a red piece of paper that comes with each sensor that gives instructions to wake the sensor. I didn’t have one of the tools mentioned so I used the deflate air method. To wake each sensor, I took a pin and pushed in the valve stem to deflate the tire and counted for 6 seconds. The instructions say 3secs but I did 6secs just to be sure. Not that I did not remove the valve, I just pushed it in as if the tire was overinflated. After 6secs, I stopped deflating and immediately triggered the sensor using the Autel TS601. The stock sensors triggered and reported their data on the Autel in 2secs or less whereas these sensors took significantly longer to respond. One sensor took ~20secs. After waking up and reading all the sensors, I plugged into the OBDII port and wrote the new sensor IDs to the ECU using the Autel. The Autel simultaneously clears the TPMS warning light during this process so there is no requirement to drive X distance for Y amount of time at a minimum speed of Z mph. You simply write the new sensor IDs to the ECU and you’re done. Don’t forget to reinflate your tires after deflating them to wake up the sensor.

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.

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! 10/22 I 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!

Worked perfectly. Original packaging and quality appeared authentic. TPMS light is off.

First of all, I’m a car DIY enthusiasm. I’m not a mechanic in any way. Just like working on car cause it brings me great joy. These Denso TPMS works for my SUV. Install was easy, took about 10 minutes or less to install them. Programming to be in sync took a little longer about 30 minutes cause I never done it before. I am confident it’ll take 5 minutes next time to program with car. Would strongly recommend these Denso TPMS, hopefully it’ll last like the OEM. Good luck have fun.

Picked one of these up as one of my PRius sensors stopped reporting at a tire repair last november. Toyota does not make it easy to locate the correct compatible TPMS sensors as there have been a number of model # changes. The 1st ones I ordered only after checking a 2nd time were not the correct part. Finally located these as options mentioned on a number of Prius chat boards as the actual sensor that is just relabeled by Toyota for its OEM TPMS Sensor. I am pleased to say it works great and installation was a breeze. I think it comes preprogramed as no one at Pep Boys had to do anything to fancy to get it to register and I didnt have to drive any distance for it to activate or show on the system and at 50% or more less than one obtained directly from Toyota or the shop. I would have bought 4 of these at the same time but wanted to see 1 did before replacing the other 3. I'll be buying these again when the other sensors crap out.

I was really puzzled by the negative reviews complaining that these sensors were DOA or shipped with dead batteries. Denso usually makes very high quality parts and these sensors (made in Japan) are no exception. I am very pleased with the sensor I purchased. HERE'S THE DEAL: These sensors are shipped "asleep" to save the battery and give them longer shelf life. You must WAKE THE BATTERY UP before your car's system will detect the sensor and read it. If you don't "wake it up," it looks and acts just like a dead battery, i.e. it "plays possum." If the shop who installs these has newer TPMS tools, they can probably trigger the sensor to "wake it up" using their tool. If you are a DIYer or the shop has an older TPMS tool, you have to wake the sensor up the old-fashioned way. Install the sensor and inflate the tire to the proper specs. Mount the inflated tire on the vehicle so the sensor is in proper range. THEN, rapidly deflate the tire for about 30 seconds. This should deflate the tire by at least 20 pounds. Reinflate the tire to proper specs and proceed with your tool trigger and, or, relearn procedure. Your tool should be able to see the sensor within minutes, if not immediately. Don't forget to copy down the sensor ID before you mount it in the tire. This procedure worked like a charm for me on my 2010 Prius. At first TechStream could not "see" the sensor, even though I had properly entered the new ID. As soon as I "woke it up" by quickly releasing about 20 pounds of pressure, TechStream started to read it. SWEET.

price is high compare with similar products, i bought it came with package it was looks good but i return immediately when i found that the amount i paid for 1 senso only not for 4

Very good quality perfect fit for my Lexus

EXCELENTE PRODUCTO, SE INSTALA Y SE ACTIVO SIN NINGUN PROBLEMA.

It worked! Item was delivered on time, original packaging was in good condition, well priced against the better names and it programmed easily. Used on a Toyota spare tire and warning lights are now off!

I bought this to replace my old TPMS sensor and was sceptical it would work in my car ( 2012 IS-F). Denso brand sensor never fails in quality and reliability!. I swapped out my old sensors and installed these new ones. Make sure you take a note of the sensor ID which will be printed in caps. Once fully fitted then simply re-program in Techstream or any tmps programming device. It worked flawlessly! I am sure this will fit many other Toyota or Lexus
