In this video, I will show you what to do if the reduced engine power message illuminates in your dash. This works on most vehicles with electronic throttle control.
If you are driving along and the reduced engine power message illuminates in your dash you should pull over turn the key off and restart it and you should be able to continue driving normally until you can get your vehicle brought in to get looked at.
In many instances, you can just have the throttle body cleaned and relearned or disconnect the battery to relearn the throttle and in most cases that will fix the reduced engine power message in the dash.
This seems to be a very common problem on a lot of newer vehicles and fortunately, just by cleaning the throttle body a lot of case lot of times it will take care of this problem without having to replace any parts.
