Abstract
Methods and systems are provided for opportunistically mitigating an intermittent degradation of an active exhaust valve. In one example, a method may include differentiating between a permanent degradation of the active exhaust valve and an intermittent degradation of the active exhaust valve and adjusting actuation of the valve based on a vehicle operating condition and a road condition to mitigate the intermittent degradation.
