The modern automobile is a symphony of interconnected parts that interact with each other in a complex exchange of energy. The Nissan ECU regulates the activity of the engine, keeping it in line with safety regulations and proper efficiency. The ECU stands for engine control unit. ECUs are electronic control systems that monitor internal combustion engines through the use of actuators, small motors that contribute to the overall integrity of the combustion process. The ECU is charged with recording and interpreting information from sensors placed throughout the engine bay and using this information to adjust the activity of the actuators. Nissan pickup ECUs are specially made to take the operation of a powerful truck into consideration. Nissan D21 ECUs and other models are similarly geared toward specific vehicles. Often, the installation of a new ECU is all that is needed to get a car's electrical system back on track, as the ECU is responsible for a good part of the car's operation. You can find plenty of Nissan ECUs on sale by browsing through the large inventory on eBay.
