Absolute Pressure & Temperature Sensor

Last update: 04 Sep. 2023

What is a pressure and temperature sensor?

The Pressure and Temperature sensor (TL) are a key component to control and monitor cooling system in EV/HEV vehicles.

The absolute pressure and temperature sensor measures temperature and pressure to optimize and ensure the internal combustion engine (ICE) performance.

It could be used to control the full air loop from the intake up to the exhaust to fulfill the on-board diagnostics and ensure the engine’s functioning in all conditions and for its entire life cycle.
