摘要:
A sensor reset system includes an engine control module and a sensor reset circuit. The engine control module is configured to receive a sensor pressure signal from a cylinder pressure sensor. The sensor pressure signal indicates a pressure within a cylinder of an engine. The engine control module is further configured to: control operation of the engine based on the sensor pressure signal; determine whether to reset the cylinder pressure sensor and generate a reset signal; and encode the reset signal to generate an encoded reset signal. The sensor reset circuit is configured to adjust an output of the cylinder pressure sensor based on the encoded reset signal to reset the cylinder pressure sensor.
