摘要：
A circuit monitors the resistance of a hot wire sensor element from the time a command to stop the engine is issued and either heats the wire to effect a self-cleaning function following a delay which is triggered by the resistance of the wire falling to a first predetermined level, or alternatively waits for the resistance to drop to a second level which is lower than the first and immediately induces heating.
