Question Do electric vehicles (EVs) require different TPMS sensors than gasoline vehicles? Answer Not always, but many EVs need faster pressure/temperature reporting intervals due to higher tire loads. Explain EVs exert greater instantaneous torque and curb weight on tires, making pressure accuracy critical for safety and range. Some EV manufacturers implement higher-resolution pressure sampling (0.1 PSI increments) or anti-interference designs. CHEPQ universal sensors include EV-optimized modes to match these protocols (e.g., Tesla’s 10-second burst interval vs. traditional 30-second).

Question What maintenance extends TPMS sensor lifespan? Answer Regular inspection, avoiding harmful sealants, proper valve stem torque, and storing sensors in cool/dry areas. Explain Inspect sensors yearly for corrosion; use only TPMS-safe sealants; torque valve stems to 4-6 Nm (not over-tighten); store spare sensors at 15-25°C (avoid extreme heat). CHEPQ sensor kits include maintenance checklists to guide technicians.
