Powertrain

In a motor vehicle, the term powertrain or powerplant describes the main components that generate power and deliver it to the road surface, water, or air.

This includes the engine, transmission, drive shafts, differentials, and the final drive (drive wheels, continuous track as in military tanks or caterpillar tractors, propeller, etc.). Sometimes ‘powertrain’ is used to refer to simply the engine and transmission, including the other components only if they are integral to the transmission.

The powertrain category trouble codes, which start with the letter P, include engine, transmission, and emission systems errors, fuel and air metering, and auxiliary emission control.
