There’s 1 in each wheel and measures the pressure and the temperature inside the tyre. The information is sent to the car so it can monitor for pressure loss. Why Would I Need To Swap Them? They have an internal battery and that won’t last forever. They rarely last longer than 10 years and the sensors are sealed units so they aren’t designed to have a replacement battery fitted. Alternatively, you may just be fitting a replacement alloy because the original was damaged (that’s why I did it). Or you might be fitting 4 different wheels. Where Are They? They are part of the valve stem… …and are screwed into the base. If you want to move the sensors over to a new wheel or are fitting replacement sensors, you’ll have to remove the tyre to access the sensor. Using a Torx10 screw driver, remove the small screw… …and pull the sensor clear. This sensor is covered in rubber swarf because the tyre was run when flat which destroyed the inside of the tyre. You can try levering out the rubber valve stem to reuse it however, you can buy replacements from smart using code A453 401 01 01. Alternatively, you can buy full replacements with the sensor and valve stem from smart using part number A453 905 17 01. The problem is that you have to have the replacement sensors coded to the car by smart. After Market Cloned Sensors Most tyre fitting garages have the ability to supply replacement sensors and clone your old sensors to the replacements. They will be cheaper than new ones from smart and won’t need coding as the car will think it’s the old sensor. I used Autel MX sensors. You just need a valve stem puller and a Torx20 screwdriver (for this specific brand of sensor). To aid fitting, add a bit of grease… …to the rubber valve stem. This helps it slide into position without binding or damaging the rubber. Offer the valve stem up to the hole… …making sure the sensor is face down against the wheel barrel. The valve stem will be poking through. Screw the valve stem puller all the way onto the valve stem. Lever against the side of the wheel so it pulls the valve stem through and seats it correctly. Here’s a video of me fitting and cloning the Autel sensors which shows the use of the valve stem puller. With the valve stem located correctly, press the sensor against the wheel barrel… …and tighten down the Torx screw. They only require 4Nm which is nearly nothing. Fitted. You can now refit and balance the tyre. Cloning The New Sensors Again, let me point you towards one of my old videos. I used the Autel TS508WF . However, I have been told that an update to this tool has removed the wireless cloning ability. Apparently is can still code the sensors by connecting to the OBD. I recommend using Autel MX Sensors: Singles: https://amzn.to/42lUxc6 Pack of 4: https://amzn.to/4i2Eoy4 Click if info helped 1 likes 6727 views Print
