If you are planning to install a mass air flow (MAF) sensor on your Nissan, then you must be aware of the 5 wire MAF sensor wiring diagrams. The wiring diagrams for these sensors are very important and provide you with a clear understanding of how the wiring should be set up. This article will explain the wiring diagrams for the 5 wire MAF sensors and how they are used in your Nissan.

The 5 wire MAF sensor is the most common type used in the Nissan models. It is used to sense the amount of air entering the engine and then adjusts the fuel mixture accordingly. The 5 wire MAF sensor has five wires: red, white, blue, green, and black. These wires are connected to the harness and then to the ECU.

The red wire is the power wire and it is connected to the battery. The white wire sends a signal to the ECU when the engine is running. The blue wire is the ground wire and should be connected to the engine block. The green wire is the signal wire and it sends the signal to the ECU when the engine is running. The black wire is the return wire and is connected to the ECU.

The wiring diagrams for the 5 wire MAF sensor are shown in the diagrams below. The diagrams show the connection of the wires to the harness and the ECU. These diagrams will help you to understand how the wiring should be set up and how the connections should be made.

Power Wire Connection

The red wire is connected to the battery and supplies the power to the MAF sensor. The wire should be connected to the positive terminal of the battery. Make sure that the connection is secure and that there is no chance of a short circuit.

Signal Wire Connection

The white wire is connected to the ECU and sends a signal to the computer when the engine is running. The wire should be connected to the ECU with a connector. Make sure that the connection is secure and that the ECU is receiving the signal correctly.

Ground Wire Connection

The blue wire is connected to the engine block and is used as a ground wire. The wire should be connected to the engine block with a connector. Make sure that the connection is secure and that the engine block is receiving the signal correctly.

Return Wire Connection

The black wire is connected to the ECU and is used as a return wire. The wire should be connected to the ECU with a connector. Make sure that the connection is secure and that the ECU is receiving the signal correctly.
