Abstract:
Methods and systems are provided for rationalizing an engine knock sensor. In one example, a method may include, responsive to an indication of an engine knock event, correlating an output of the engine knock sensor with an output of an on-board microphone to determine degradation of the engine knock sensor. By rationalizing the engine knock sensor against another on-board sensor (e.g., the on-board microphone), diagnostic fidelity may be increased.

Claim (Index 14):
The method of  claim 13 , further comprising:\n determining frequency components of the knock sensor output sampled during the detected knock event via a fast Fourier transform; determining frequency components of the microphone output sampled during the detected knock event via the fast Fourier transform; maintaining the spark timing at the retarded spark timing in response to a dominant frequency of the determined frequency components of the knock sensor output matching a dominant frequency of the determined frequency components of the microphone output; and reverting the spark timing to the first spark timing in response to the dominant frequency of the determined frequency components of the knock sensor output not matching the dominant frequency of the determined frequency components of the microphone output.
