Review on 🔧 Autel MX-Sensor TPMS 2-in-1 Tire Pressure Monitor Sensor - 315MHz and 433MHz, OEM Replacement with Screw-in Rubber Valves (Pack of 4) by Corey Moulton

These are fantastic sensors. They work in almost every car. I have seen negative reviews and would like to help clear things up. For them to work and for your car to recognize them, two things need to happen (which turn off the TPMS sensor warning light). First, understand that TPMS sensors transmit their ID. # and current tire pressure. Your car will ignore them unless it knows to look for you. Imagine your car has a table with 4 or 5 slots for your 4 tires and maybe a spare tire and on that table it says TIRE1:123456, TIRE2:ABCDEF, TIRE3:140GNB, TIRE4:20RMS0. If these TPMP sensors are not programmed to read 123456, ABCDEF, 140GNB, 20RMS0, your vehicle will flash a warning light. It also comes on with a warning light if the TPMS system is faulty or the tire pressure is too low. The codes don't have to be the ones I listed. Just remember that these are random letters and numbers stored in your vehicle. You can change this "table" in your car if your sensors already have ID numbers, but you'll need a tool to do that. Installation: 1: Install the sensor in the wheel and program it. Programming a sensor means you take an Autel or Bartec TPMS programmer and give those sensors an ID. They come blank, so they won't work without programming them. Give them the code. TIP: If you can figure out the codes for each of your current or old tire/TPMS sensors (or at least the ones the car recognizes), you can program those sensors to match the old sensors and everything will work up work magically. You don't even have to do step 2 to get rid of this TPMS.2 warning light. Program your vehicle to recognize the new TPMS sensor IDs. When you buy these sensors, the easiest way is to match them with the ID of your old sensor, which your car already recognizes. Regardless of what you do, when you create new sensor IDs, you need to tell your car what the new IDs are. This can be done with more advanced TPMS machines from Autel or Bartec. Your dealer can also do this. THERE IS ONE MORE STEP: Press the TPMS reset button in your vehicle. It's usually a small black button located under the steering wheel, perhaps much further down on the underside of the plastic next to your feet. Contrary to popular belief, the car is not reprogrammed to learn new sensors. All of this causes the car to re-learn which of the 4 tires is where in the chart (front left, rear right, etc.). This is only necessary for vehicles that display individual tire pressures. That's all. If you want to know what your current sensor IDs are so you can use them to program the same IDs to speed up this whole process, most auto repair shops (Autozone, O'Reilys, etc.) can get you one for free. HOWEVER none of the ones I could find allowed you to use it at all with programming skills. Most tire shops I've contacted will program these sensors and program my car for around $6 per tire. but most of them also wanted me to make an appointment. I'm just giving the approximate numbers I found. I hope this helps at least one person who wants to buy cheap sensors but doesn't really know what they do. These versions are programmable which is totally optional unless you want to use them on many different types of vehicles or you want them to fit your current tires (either because they are broken or because you have 2 wheel sets (summer/winter) and You want to change them without reprogramming the car.
