Introduction to Pressure Sensors in Commercial Trucks

Pressure sensors are critical components in modern commercial trucks, ensuring optimal engine performance and efficiency. These sensors measure the pressure of fluids or gases within the engine, providing vital data to the engine control unit (ECU) ¹. This information is essential for maintaining the balance between performance and fuel efficiency, as well as for preventing potential engine damage.

How a Pressure Sensor Works

A pressure sensor operates by converting pressure into an electrical signal. This is typically achieved through a diaphragm or a piezoelectric element that deforms under pressure, generating a corresponding electrical output. The sensor then sends this signal to the ECU, which interprets the data and adjusts engine parameters accordingly ².
