Infiniti Tire Pressure Sensor 40700-1AA0A Original TPMS, Direct Replacement, Real-time Tire Pressure Monitoring

When your Infiniti dashboard lights up with a tire pressure warning or a tire shows abnormal pressure fluctuations and cannot reset, the TPMS sensor battery may be dead or internal components aged; replacement is necessary. The sensor monitors tire pressure and temperature and transmits data wirelessly to the vehicle receiver module to keep track of each tire’s state and prevent blowouts or underinflation. This is an OEM-direct replacement design; OEM number 40700-1AA0A; fits Infiniti Q50, Q70, QX60, QX80, and other models. Installation requires a professional technician to relearn and pair the sensor with the vehicle system; after installation, check valve stem seal for leaks.
