Question
What causes false TPMS warnings?
Answer
Temperature swings, faulty sensors, incorrect relearn, or RF interference from nearby devices.
Explain
Cold weather (10°C drop = 1 PSI loss) triggers warnings; weak sensors send erratic data; incomplete relearn leaves ECUs confused. CHEPQ tools clear false warnings and run “validation tests” (drive 5 miles) to confirm if the alert is real.
