An AEM wideband O2 sensor is designed to accurately measure the air-fuel ratio of an engine. It is a helpful tool for tuning your engine and making sure it is running efficiently. This article will discuss the wiring diagram for an AEM wideband O2 sensor and provide tables and frequently asked questions for easy reference.
Wiring Diagram
The wiring diagram for an AEM wideband O2 sensor is relatively simple. There are only four wires you need to connect to your vehicle’s wiring harness:
| Wire Color | Function |
|---|---|
| Red | 12V Power |
| Black | Ground |
| Yellow | WBO Signal |
| Green | Analog Voltage Output |
Once you have properly connected these four wires, your AEM wideband O2 sensor should be ready to go. It is essential to make sure that the connections are tight and that the connections are made according to the manufacturer’s instructions.
Red Wire
The red wire on the AEM wideband O2 sensor is used to connect the sensor to a power source. This wire should be connected to a 12V power source that is only active when the ignition is turned on. This wire can also be connected to an accessory position on the ignition switch. It is important to make sure that this wire is connected to a clean and secure power source.
Black Wire
The black wire on the AEM wideband O2 sensor is used to ground the sensor. This wire should be connected to a clean and secure ground source. It is important to make sure that this wire is grounded correctly to avoid any performance issues or signal interference.
Yellow Wire
The yellow wire on the AEM wideband O2 sensor is used to send the WBO signal to the ECU. This wire should be connected to the WBO input on your ECU. It is essential to make sure that this wire is connected to the correct input on your ECU to avoid any issues with the signal.
Green Wire
The green wire on the AEM wideband O2 sensor is used to send the analog voltage output to a data logger or gauge. This wire should be connected to the analog input on your data logger or gauge. It is important to make sure that this wire is connected to the right input on your data logger or gauge.
