Pressure sensor testing system for motor vehicle, has pressure impacting device provided separate from internal combustion engine of motor vehicle, so that test pressure is adjusted independent of operating condition of engine

摘要

The system (2) has a pressure impacting device (6) causing an impact on a fluid that flows with a testing pressure, which acts on a pressure sensor (4) to be tested. The pressure impacting device is provided separate from an internal combustion engine of a motor vehicle, so that the test pressure is adjusted independent of an operating condition of the internal combustion engine. The pressure impacting device has a pump (26) and a storage unit for the medium. An independent claim is also included for a method for testing a pressure sensor of a motor vehicle.
