Indirect tire pressure monitoring determines low by monitoring which sensors?

Indirection in tire pressure monitoring relies on wheel-speed sensors to sense differences in how fast each wheel rotates. When a tire is underinflated, its effective diameter is smaller, so it tends to rotate slightly faster than the properly inflated tires. The TPMS module compares the rotation rates from all wheels; if one wheel runs faster by a threshold, it flags a low tire pressure warning. The sensors used here are the wheel-speed sensors, which are often part of the ABS system. Oxygen sensors measure exhaust gas, tire temperature sensors gauge heat, and the ABS system itself uses wheel-speed data for braking control but is not the sensor that detects low tire pressure.
