Question
How often should TPMS sensors be tested or replaced?
Answer
Test annually; replace every 5-7 years or if battery/signal issues arise.
Explain
Routine testing (via CHEPQ tools) checks battery voltage (>2.7V = good) and RF signal strength (> -80 dBm = reliable). Sensors past 7 years often have intermittent failures—CHEPQ recommends proactive replacement for fleet vehicles to avoid roadside breakdowns.
