Question
Why do some TPMS sensors transmit more data in cold weather?
Answer
Cold temperatures increase battery internal resistance—sensors send more frequent packets to ensure ECU reception.
Explain
At -20°C, battery voltage drops; sensors transmit every 15 seconds (vs. 30 seconds at 25°C) to avoid signal loss. CHEPQ tools show transmission frequency to diagnose battery health.
