Abstract
In systems, such as sensor systems, an output signal of the system (e.g. output of the sensor corresponding to a sensed characteristic) can be generated and provided. In response to a detected error, the output signal can be adjusted to generate an error indication signal pulse to indicate that an error has been detected. The output signal can then be adjusted to return to a signal level corresponding to the sensed characteristic. In response to the error being resolved, an error resolution signal pulse can be generated.

An error detection and signaling method for a sensor system, comprising:
- sensing, by a sensor of the sensor system, a physical characteristic and generating an output signal corresponding to the sensed physical characteristic;
- detecting an error associated with the sensor;
- adjusting a signal level of the output signal to an error signal level and generating an error indication signal pulse based on the detection of the error by the fault detector;
- adjusting the signal level at the error signal level to a sensing signal level corresponding to the sensed physical characteristic based on the error indication signal pulse to output the output signal corresponding to the sensed physical characteristic;
- and
- adjusting the signal level at the sensing signal level to the error signal level and generating an error resolution signal pulse in response to a resolution of the detected error to indicate the resolution of the detected error.
