    摘要: An engine control module and method configured to correct an engine crank sensor signal for errors in an apparent location of a tooth edge on a crank wheel is provided. A correction factor is determined based on a first formula if a comparison of adjacent pulse intervals to predetermined thresholds indicates that a tooth edge appears to be abnormally late, and determined based on a second formula if a comparison of adjacent pulse intervals to other predetermined thresholds indicates that a tooth edge appears to be abnormally The correction factor is set to a null value if the correction factor is not determined based on the first formula or the second formula; and operating an engine based on the correction factor.
