If I clear the codes with the engine running, the reduce power message goes away and does not return until the next time I shut the car off and restart it. If you look at the second error in the screenshot I uploaded above it looks like the code was triggered when the engine was only at 96 RPM, which would have to be during ignition. Also there's definitely a change in the engine sound when it is in reduced power mode. The exhaust resonates inside the car more, even at idle.
