TPMS in the Toyota Prius: The TPMS in the Toyota Prius is designed to monitor tire pressure and alert the driver when it falls below the recommended threshold. However, this system can give false alerts for several reasons:

Temperature Fluctuations: Significant changes in weather, especially in Pakistans hot summers and cold winters, can lead to temporary pressure changes that TPMS may interpret as a fault.
Underinflated Tires o r Overinflation: If the tires are over o r under-inflated, TPMS may incorrectly detect low o r high pressure.
Sensor Malfunctions: The TPMS sensors may malfunction due to dirt, corrosion, o r age, leading to inaccurate readings.

Troubleshooting:

Manually Check Tire Pressure: Use a reliable pressure gauge to verify the actual pressure of each tire.
Reset the TPMS: After adjusting tire pressure, reset the system to ensure it reflects accurate readings.
Sensor Maintenance: Clean o r replace malfunctioning sensors as needed.
Seek Professional Help: If the issue persists, consult a Toyota dealership o r certified mechanic.
