The Tire Pressure Monitoring System (TPMS) is specifically designed to monitor the air pressure in a vehicle's tires, including those on trucks. This system uses sensors either inside the tires or mounted on the wheels to continually check the pressure and provide real-time data. If tire pressure falls below a certain threshold, the TPMS alerts the driver, helping to prevent issues such as tire blowouts, reduced fuel efficiency, and impaired handling.

In contrast, the other devices listed, such as Engine Management Systems, Fuel Injection Sensors, and Brake Fluid Indicators, serve different functions. Engine Management Systems optimize engine performance; Fuel Injection Sensors regulate fuel flow for combustion efficiency; and Brake Fluid Indicators monitor the brake fluid level for safety in braking systems. While these systems are essential for vehicle operation and safety, they do not pertain to monitoring tire pressure specifically, which is the primary function of the TPMS.
