Sensors

Engine and Transmission

Delphi sensors maximize engine and transmission performance by monitoring engine, battery, transmission and fuel parameters such as air/fuel ratios, evaporative emissions, torque, and temperature. We are continually developing breakthrough sensing and actuating solutions to help optimize emissions control, fuel economy, and driveability.
