A mass airflow sensor (MAF) is an important component of any modern vehicle’s fuel injection system. It measures the amount of air entering the engine, which allows the engine control unit (ECU) to adjust the fuel delivery accordingly. The most common type of MAF is the five-wire MAF, which is found in many cars from the mid-1990s onwards. If you’re looking to install a new MAF sensor or repair an existing one, it’s important to understand the wiring diagram for the five-wire MAF. In this article, we’ll take a look at the five-wire MAF wiring diagram and how it works.

What Is a Five-Wire MAF Sensor?

A five-wire MAF sensor is a type of mass airflow sensor that measures the amount of air entering the engine. It consists of five wires: two wires that measure the amount of air entering the engine, two wires that measure the temperature of the incoming air, and one wire that measures the engine’s RPM. This type of MAF sensor is used in many modern cars and is relatively easy to install and maintain.

How Does the Five-Wire MAF Sensor Work?

The five-wire MAF sensor works by measuring the amount of air entering the engine and then sending this information to the ECU. The ECU then uses this information to adjust the fuel delivery accordingly. The two wires that measure the amount of air entering the engine are connected to the intake manifold and the air filter, while the two wires that measure the temperature of the incoming air are connected to the intake manifold and the throttle body. The last wire measures the engine’s RPM. This information is then sent to the ECU, which uses it to adjust the fuel delivery.

Five-Wire MAF Sensor Wiring Diagram

The five-wire MAF sensor wiring diagram is shown below. It consists of five wires: two wires that measure the amount of air entering the engine (A and B), two wires that measure the temperature of the incoming air (C and D), and one wire that measures the engine’s RPM (E).

The first step in installing a five-wire MAF sensor is to connect the two wires that measure the amount of air entering the engine (A and B) to the intake manifold and the air filter. Then, the two wires that measure the temperature of the incoming air (C and D) should be connected to the intake manifold and the throttle body. The last wire (E) should be connected to the engine’s RPM sensor. Once all the wires are connected, the MAF sensor is ready to be used.

Troubleshooting a Five-Wire MAF Sensor

If the engine is not running as expected, it may be due to a faulty MAF sensor. The first step in troubleshooting a five-wire MAF sensor is to check the wiring diagram to make sure all the wires are connected correctly. If the wiring is correct, then the next step is to check the voltage at each of the five wires. If the voltage is not within the specified range, then the MAF sensor should be replaced.

Conclusion

A five-wire MAF sensor is an important component of any modern vehicle’s fuel injection system. It measures the amount of air entering the engine, which allows the engine control unit (ECU) to adjust the fuel delivery accordingly. The wiring diagram for the five-wire MAF is relatively simple and can be easily understood. If the engine is not running as expected, it may be due to a faulty MAF sensor. The first step in troubleshooting a five-wire MAF sensor is to check the wiring diagram to make sure all the wires are connected correctly. If the wiring is correct, then the next step is to check the voltage at each of the five wires. If the voltage is not within the specified range, then the MAF sensor should be replaced.
