Sensors measure, feel and count. Sensor signals are essential for numerous measurement and control functions as well as for safety and comfort reasons.
The vacuum pressure inside the engine intake manifold is measured by the intake manifold pressure sensor or simply pressure sensor. Using this information along with signals from other sensors, the D-Jetronic control unit calculates the optimum amount of fuel for each load and supplies it to the fuel injectors.
Air and fuel must be injected into the engine in a precisely defined ratio. To do so, air-flow meters measure the actual air flow and forward the measured values to the engine‘s control technology.
The wheel speed sensor, which is particularly important in ensuring the proper functioning of the anti-lock braking system (ABS) developed by Bosch in 1978 is being reproduced since 2024. The sensors were no longer available for many vehicles built between 1978 and 1998. For the first ABS generations, there were practically no more sensors available as spare parts.
Versatile and reliable: Bosch lambda sensors are an effective solution to ensure compliance with emission standards. Ever since 1976, they have contributed to reducing the emissions of motor vehicles.
The hot-film air-mass meter (HFM) and the hot-wire air-mass meter (HLM) are available through the Bosch eXchange program. Both sensors are responsible for determining the correct ratio between air mass and fuel quantity and forwarding the values to the engine control.
Temperature sensors limit the injection time of the cold start valve depending on the engine temperature. Fitted into a hollow stud, they are installed at a location where the engine temperature can be measured properly. Reproduced temperature sensors are equipped with electronics making them almost wear-free.
