MS Motorservice offers separately replaceable fuel pressure sensors
Share:

MS Motorservice International is significantly expanding its sensor product range. Following extensive enhancements in the area of exhaust gas sensors, the spare parts specialist will now be offering the aftermarket 13 fuel pressure sensors (also known as fuel rail pressure sensors). 


The articles that are currently available cover a global fleet of more than 50 million vehicles and the company is planning to expand its portfolio even further. Many providers only make the distributing pipe (rail) available to purchase as a complete unit along with all the attachments. However, Motorservice offers the pressure sensor as a separate spare part. This means that only the component that is actually defective needs to be replaced making this a much more environmentally friendly and cost-effective option. 

MS Motorservice says the sensors also boast outstanding product quality. As a sales organisation for Rheinmetall’s aftermarket activities, Motorservice acquires a large proportion of its range internally from within the group, including the subsidiary Pierburg. This means that the internationally active spare parts specialist has the know-how and high quality standards of a large international automotive supplier.

The fuel pressure sensor is installed on the distributing pipe, where it measures the fuel pressure and acts as a sensor for pressure control and metering purposes. The engine control unit provides the sensor with a supply voltage of 5 V. There are also ground and signal output connections. 

Moving through a bore in the sensor, the fuel pressure reaches a diaphragm equipped with a sensor element. The diaphragm is distorted, an action that the sensor element converts into electrical voltage and is output to the control unit. The voltage signal experiences a linear increase as the pressure rises. If the control unit identifies a fault affecting the sensor, it outputs a substitute value and limits the injected fuel quantity and the fuel pressure.
