Techniques are described for determining an amount of fuel that is consumed by the body components of a vehicle, based at least partly on sensor data describing the operations of the body components and/or the location of the vehicle. A vehicle is equipped with a body that has any suitable number of body components that perform operations not directly associated with the translational movement of the vehicle from one location to another. Fuel is consumed to provide power (e.g., through power take off) to operate the body components. The vehicle includes sensor device(s) configured to sense the operations of the body components and generate sensor data that describes the operations of the body components. The sensor data is analyzed to determine an amount of fuel that is consumed to power the operations of the body components.

A deterioration estimator for an electronic throttle device allows a throttle valve to be driven by a drive mechanism. The throttle valve is continuously operated to open and/or close. If operated to open, it opens from a first opening position, which is on a closed side from an opener opening position and in which the throttle valve is biased to an open side by an opener mechanism, to a second opening position, the second opening position being on an open side from the opener opening position with the throttle valve being biased to the closed side by the opener mechanism. If operated to close, the throttle valve is operated to close from the second opening position to the first opening position. A deteriorated condition of the electronic throttle device is estimated by detecting a behavior of the drive mechanism when the throttle valve passes by the opener opening position.

A method for recognizing an error in a sensor signal during operation of a fuel injector of an internal combustion engine. In the method, a switch valve of the fuel injector is activated with the aid of an activation signal, and the sensor signal is detected as a signal of a sensor, which is provided for the purpose of detecting characteristic operating points of the fuel injector, in a respectively predefined time window of the sensor signal, which includes a point in time of a characteristic operating point of the fuel injector. At least one property of the sensor signal is determined, which includes a signal level and/or a rise time. It is determined, based on the at least one property of the sensor signal, whether an error is present.
