So, I pushed the boat out and got TPMS fitted to my new bike before I picked it up. Now I've been reading through the manual (which is a bit of a first for me) and this is what it says about the tyre pressure monitoring sensors: Tyre Pressure Sensor Batteries When the battery voltage in a pressure sensor is low, a message will be shown in the instrument display and the TPMS symbol or message will indicate which wheel sensor has the low battery voltage. If the batteries are completely flat, only dashes will be shown in the instrument display, the red TPMS warning light will be on and the TPMS symbol will flash continuously. Contact your authorised Triumph dealer to have the sensor replaced and the new serial number recorded in the spaces provided in the Sensor Serial Number section. Am I right in thinking that when the battery goes flat you basically throw the sensors away and pay for new ones? These things aren't cheap! Also, if anyone has any idea about how long the batteries last, that would be useful...
I believe there are videos on YT which show the batteries can be changed. It’s not easy, you have to dig them out by removing the gunk (I don’t know if it’s silicon or something) that seals them in and then recoding them to the bike but it’s doable.
I worked for Kia Motors before retirement and the TPMS sensors fitted to their cars have a 10year life. If a battery fails or looses charge they are thrown away. Alfie
