It is estimated that 14 million sensors will fail this year due to worn out batteries and by road conditions which damage the sensors. Sensors are electronic units mounted directly within the tire wheel assembly. TPMS sensors contain an air pressure sensing element, and depending on the application, may also monitor tire air temperature and provide other advanced monitoring features transmitted wirelessly to the vehicle's receiver. TECH OE-R OE replacement sensors are direct replacements for original sensors. TECH Hybrid 2.0 sensors are the fastest configurable sensors in the market today. TECH TPMS sensors are available for all recent vehicle models and years. In addition, the TECH website includes a handy TPMS vehicle manufacturer, model and year look up section which quickly identifies the correct TPMS sensor for that particular vehicle.
