<p>A method for detecting noise on a conductive path (34) utilized for conducting combustion signals produced by a combustion sensor (26) of an internal combustion engine (10) is disclosed. Essentially, the combustion sensor (26), when operable, produces combustion signals responsive to the occurrence of combustion conditions in a combustion chamber (20) of the engine (10). According to the present invention, the conductive path (34) is monitored for noise signals at a time when the combustion signal is not expected to occur, such that, logically, any noise signal present will be discovered. A controller (30) is connected to a conductive path (34) for conducting combustion signals (38A,38B) produced by a combustion sensor (26) and is operable to monitor the conductive path (34) for noise signals during a time when it is not monitoring for an expected combustion signal. <IMAGE></p> |
