Automotive Powertrain Sensors: Trends & Forecasts to 2021 MR-AB-016

Two major concerns for automotive engineers are how best to maximize fuel economy and to reduce emissions. Powertrain sensors, which measure temperature, pressure, rotational speed and other vehicle performance parameters, are central to both.

There is also a trend in the powertrain sensor industry toward higher temperature and electromagnetic compatibility requirements, due largely to the increasing deployment of smaller engines.

This exclusive report from ABOUT Automotive focuses on the following key areas:

Temperature sensors:

• Manifold air temperature sensor
• Engine coolant temperature sensor
• Transmission oil temperature sensor
• Engine oil temperature sensor
• Boost air temperature sensor

Pressure sensors:

• Manifold absolute pressure (MAP) sensors
• Barometric pressure (BARO) sensors
• Engine oil pressure sensors
• Fuel rail pressure sensors
• Boost pressure sensors
• Air conditioning (A/C) pressure sensors
