Tire pressure monitoring systems (TPMS) are designed to alert drivers when the air pressure in one or more tires is too low. This is an important safety feature, as under-inflated tires can lead to poor handling, reduced fuel economy, and even a blowout. There are two main types of TPMS: direct and indirect. Direct TPMS use sensors mounted inside the tires to measure the air pressure and send the information to the vehicle's onboard computer. Indirect TPMS, on the other hand, uses the vehicle's ABS (Anti-Lock Braking System) sensors to estimate the air pressure based on the rotational speed of the tires. When a TPMS sensor detects a low tire pressure, it sends a signal to the vehicle's onboard computer, which then displays a warning on the dashboard. The warning light will typically be either an exclamation mark within a horseshoe or a flat tire icon. One of the most common issues with TPMS is a dead or weak battery in the sensor. This can cause the sensor to stop transm ... read more
