1. A method for monitoring the operation of a vehicle under adverse conditions, the method comprising:

  • activating at predetermined intervals an air diverter that is installed on a vehicle to sample incoming air upstream from and entering an air filter installed on the vehicle;

    measuring via a contaminant detection sensor installed on the vehicle an amount of particulate contamination in the upstream air sampled by the air diverter at the predetermined intervals;

    monitoring via the contaminant detection sensor the measured amount of particulate contamination in the upstream air for a high level of particulate matter outside of an acceptable range; and

    the contaminant detection sensor signaling to an integrated circuit module an occurrence of an adverse condition relating to operation of the vehicle in response to determining that the monitored measured amount of particulate contamination in the upstream air has a high level of particulate matter outside of an acceptable range.
