Question
What is the RF range of a TPMS sensor?
Answer
1-3 meters, depending on vehicle metal content and sensor power.
Explain
Sensors transmit 10-20 mW of power—enough to reach the ECU antenna (usually under the dashboard). EVs with thick metal battery packs may have shorter range (1-1.5 meters); CHEPQ boosts EV sensor power by 15% to compensate.
