Exhaust system having sensor placement detection

A method of determining a placement-related parameter of an exhaust control system, comprising:

• determining a change in an operational parameter of an engine;
• determining a change in an exhaust parameter of an exhaust gas of the engine at a location downstream of the engine;
• measuring an elapsed time between determining the change in the operational parameter and determining the change in the exhaust parameter;
• and
• determining the placement-related parameter based on the elapsed time.

A power system, comprising:

• an engine configured to combust fuel and generate combustion exhaust gas;
• an exhaust passage configured to receive a flow of the exhaust gas from the engine;
• an exhaust sensor associated with the exhaust passage and configured to generate a first signal indicative of an exhaust parameter of the exhaust gas;
• an operational sensor associated with the engine and configured to generate a second signal indicative of an operational parameter of the engine;
• and
• a controller in communication with the engine, the exhaust sensor, and the operational sensor, the controller being configured to:
• detect a change in the operational parameter based on the second signal;
• detect a change in the exhaust parameter based on the first signal;
• measure an elapsed time between the detection of the change in the operational parameter and the detection of change in the exhaust parameter;
• and
• determine a placement-related parameter of the exhaust sensor based on the elapsed time.
