1. A method, comprising:
- during combustion operation in an engine, determining a fluid leak of a component including one or more of the engine with a combustion chamber, a transmission, and a radiator in a wheeled vehicle via a strain sensing element located underneath the component in an underbody cover positioned below and spaced away from the component and included in the wheeled vehicle; and
adjusting a vehicle operation in response to determining the fluid leak in the engine, the transmission, or the radiator;
where adjusting the vehicle operation includes one or more of decreasing a torque output and decreasing boost.

6. A method, comprising:
-
receiving signals from a plurality of strain gauges on an underbody cover positioned below and spaced away from one or more of an engine, a transmission, and a radiator and included in a wheeled vehicle, during combustion operation in the engine; determining a leakage of one or more of the engine, the transmission, and the radiator based on the signals received from a corresponding strain gauge, the corresponding strain gauge being a strain gauge in the plurality of strain gauges; and adjusting a vehicle operation in response to identifying which of the engine, the transmission, or the radiator is leaking; where adjusting the vehicle operation includes one or more of decreasing a torque output and decreasing boost. - View Dependent Claims (7, 8, 9, 10, 11, 12)

13. A system, comprising:
-
first, second, third, and fourth strain gauges vertically displaced underneath and spaced away from one or more of an engine, a transmission, and a radiator on an underbody cover of a wheeled vehicle; and a controller with computer readable instructions stored in memory for; determining a fluid leakage in response to a strain gauge measuring a strain of the underbody cover exceeding a threshold strain, during combustion operation in the engine; and adjusting a vehicle operation in response to identifying which of the engine, the transmission, or the radiator is leaking. - View Dependent Claims (14, 15, 16, 17, 18)
