I parked my car yesterday and was straightening the tires when I saw my RPM go up from about 700 to 1000. Why does it do this?
In: Engineering
If you were stopped and you noticed this, it’s because most vehicles have power steering now. Power steering takes power from the running engine to operate the steering pump. When you turn the wheels, you operate the pump, increasing engine rpm. Try putting it in park and turning your wheels, the same should happen. Also in park try turning the a/c off and on. The a/c pump also runs off engine power and will effect the rpm.
