Understanding the average cost to replace TPMS sensors is essential for vehicle owners to budget for maintenance and repairs. This article delves into the world of TPMS sensors, exploring their importance, types, and the factors influencing their replacement cost.
Introduction to TPMS Sensors
TPMS sensors are small devices attached to the valve stem or tire sidewall inside each wheel. They are responsible for measuring the tire pressure and temperature, then transmitting this information to the vehicle’s onboard computer. The system’s primary function is to warn the driver if the tire pressure drops below the recommended level, thus preventing potential accidents caused by underinflated tires.
Types of TPMS Sensors
There are two main types of TPMS sensors: direct and indirect.
– Direct TPMS sensors measure the air pressure inside each tire and send the data directly to the vehicle’s computer.
– Indirect TPMS sensors, on the other hand, use the vehicle’s anti-lock braking system (ABS) and speed sensors to estimate tire pressure by monitoring the differences in wheel rotation speed, which can indicate underinflation.
