Question
Why does a TPMS sensor lose signal intermittently?
Answer
Intermittent signal loss stems from RF interference, weak battery, antenna damage, or placement issues.
Explain
TPMS sensors transmit low-power RF (315/433 MHz); metal shielding from aftermarket rims, moisture in wheel wells, or failing internal batteries weaken signals. CHEPQ diagnostic tools analyze LF wake-up behavior and RF packet strength to pinpoint the exact cause (e.g., distinguishing metal interference from battery decay).
