Whole vehicle fault detection using centrally located gas analysis

A system comprising:

• a sensor housing containing one or more sensors, the sensor housing situated at a confined location of a vehicle, the confined location environmentally partitioned from any sample location of the vehicle;
• a pump configured to force one or more fluid samples from one or more sample locations to the sensor housing via a tube;
• a sensor of the one or more sensors of the sensor housing, the sensor configured to generate a sensor measurement for the one or more fluid samples from the one or more sample locations;
• and
• a controller including a processor coupled to the one or more sensors, the controller configured to identify a vehicle status for the one or more sample locations of the vehicle based upon the sensor measurement received from the sensor, wherein, in response to the controller determining that the sensor measurement indicates a fault, the controller is further configured to:
• obtain a second sensor measurement for a second fluid sample from the sensor;
• and
• determine whether the second sensor measurement indicates the fault in the vehicle status.
