Question
How to verify TPMS sensor battery life in indirect TPMS systems?
Answer
Monitor sensor signal strength and check battery voltage via diagnostic tool.
Explain
Indirect TPMS sensors (e.g., Toyota) have 5-7 year battery life. CHEPQ tools read sensor battery voltage (<2.0V indicates low life) and signal strength (>80% is normal)—replacing sensors before battery failure avoids false low-pressure warnings.
