The BMW 733i Fuel Pressure Sensor provides accurate, real-time pressure information to the engine management system, ensuring precise fuel delivery for responsive throttle and reliable power. Highly regarded by classic BMW enthusiasts, this Fuel Pressure Sensor transmits changes of pressure developed by the mechanical fuel pump to the control module with a clear voltage signal every millisecond. The sensor fits the original 733i from 1977 through 1984 manual or automatic transmission models. The sensor drops into the original rail mount so owners don't have to bother with complicated retrofits. Factory level reliability is achieved. The in-line six is able to idle smoothly, start quickly, and pull harder all thanks to the Fuel Pressure Sensor which keeps pressure in the tight of limits. Also, it saves fuel and cuts emissions which means it also offers efficiency and safety. Made with sealed electronics and corrosion resistant terminals, the Fuel Pressure Sensor resists heat soak and vibration that can plague older engine bays, and it will last a long time even on BMW sedans applied every day. In the engine compartment of each 733i, the BMW Fuel Pressure Sensor is a perfect match to the original Bosch injection hardware. If there are spikes or drops in the pressure, the component warns the dashboard, informing the driver at an early stage and preserving the 733i's expected smooth feel. The calibration memory of the Fuel Pressure Sensor allows it to maintain accurate operation through an almost infinite number of cycles, thereby ensuring that combustion is in line with the air mass and the ignition timing. Owners say that the 733i runs cooler and feels snappier, a testament to BMW's decision to go heavy-duty. For the enthusiasts dedicated to preserving their vintage BMW, fitting a new Fuel Pressure Sensor is a straightforward high impact upgrade, which keeps performance alive on the iconic 733i.
