An I get replacement sensors if needed? Is the sensor battery replaceable? The sensor’s battery is not replaceable, but the sensor is replaceable. Can pressure be displayed in PSI or only in BAR as in the pictures. It can display in PSI or in BAR, just press button set for 2 seconds to change different display as the following picture. How far away from the receiver can the button be? A: The effective distance between TPMS button and “T” antenna is 1m, the receiver and button is within 50m, so you can use our product in universal 12V cars. TPMS monitors tire temperature and pressure in real-time. 83% of tire pressure loss is estimated to occur gradually – often without being noticed by the driver. Correct tire pressure helps reduce fuel consumption, and reduces tire wear, the risk of aquaplaning and lack of traction. New technology brings good performance. Low voltage input :10ï½26V.
