Abstract
A system for controlling ignition timing in an engine wherein a knocking signal is generated by a sensor in response to knocking. The operation of the sensor is monitored, and when a fault in its operation is detected, a dummy signal, instead of the knocking signal is used to control engine timing. The dummy signal causes the engine timing to be retarded to a value at which knocking is unlikely to occur.
