International 4100 Air Flow Sensors

An essential component in the diesel electronic control system, this sensor provides the vehicle powertrain control module (PCM) with Manifold Absolute Pressure (MAP) . The PCM uses this to control boost pressure and calculate accurate fuel injection quantity. Failure of this component can result in a check engine light, poor drivability and excessive exhaust emissions.

This manifold absolute pressure sensor is designed to match the function of an original sensor on specified vehicles, and to help accurately monitor manifold pressure when an original sensor has failed from heat or internal component damage.
