Bosch Performance sensor for measuring boost pressure with integrated charge air temperature sensor Boost pressure sensor 0.5 - 4.0 bar / 56 psi Bosch Performance sensor for measuring boost pressure with integrated charge air temperature sensor Compatible with our Displays / Gauges When it comes to engine sensors, exhaust temperature measurement is often prioritized, but monitoring boost pressure, intake air, charge air, or ambient temperature is also essential. Boost pressure sensors, also known as Manifold Absolute Pressure (MAP) sensors, measure the pressure in the charge air system to indicate engine load. These sensors are typically used in "Speed/Density" or "Manifold Pressure Controlled" engine management systems that do not use a mass air flow meter (MAF).
