Question
Why do some TPMS tools display “RSSI value” for sensors?
Answer
RSSI (Received Signal Strength Indicator) measures RF signal strength (-dBm), indicating sensor health.
Explain
RSSI > -80 dBm = strong signal; < -95 dBm = weak (replace sensor). CHEPQ tools use RSSI to prioritize sensor replacement for fleets.
