A: Maybe the battery was run out of power, please replace the batteries. Our sensors's battery style is CR1632. Q:Why the TPMS reading is different with other pressure tester? A: Please test the tire pressure when the car is running, if the car stops, the TPMS reading is not correct. Q: Why four tyre reading is different? A: If the car stops, the read is different and not correct. The pressure is affected by the temperature. If the temperature of the four tires is different, the reading will be different. The higher the temperature, the higher the pressure.
