2002 nissan sentra ecu circuit diagram - Your 2002 Nissan Sentra's ECU is a very complex device. The ECU is in charge of controlling several aspects of your vehicle's functions, such as ignition, fuel injection, and vehicle speed. The ECU is a microprocessor with a set of inputs and outputs that communicate with the other devices in the vehicle. Without the ECU, the same tasks performed by the engine, transmission, and throttle body would be much more complex. Instead of the small gear turning the big large gear, the task would be more like matching an elevator's shaft to the mechanical elevator. The ECU is plugged into the engine's data bus, which is monitored and controlled by the ignition coil and fuel injectors. The ECU is the brain of your Sentra and is a very important part of its operation.
This ECU error code may have four or five options, and you can choose from the four or five options. Option one is the engine light will come on, which is more than OK, but also you can choose three or four options. Four of those choices will automatically allow your car to start. But the five or four choices, one of them that you have to have your key in to allow your vehicle to start. In that case, you have to take a chance on getting stranded on the side of the road, with no transportation. Your auto repair technician will have to change the part that is affected by the error code.

This circuit diagram shows the current (continuous current) that flows through the ECU during the process of delivering power to your engine. The ECU is a signal switching power, its on and off times are synchronized. This allows the ECU to control your engine with far more precision than if the ECU were to send its signals intermittently.
This circuit diagram of the ECU's programmable circuit board shows the relationship between the power source and the circuit board, and how the circuit board contains the ECU's programmable circuit board. The ECU's programmable circuit board contains 15 sets of IGBTs to switch the power from the Vcc, the main power source. When the power from the Vcc is off, the 15 sets of IGBTs are turned off. The 15 sets of IGBTs are powered by each of the power outputs from the ECU's power generator circuit board. The programmable 0b46394aab
