Oxygen Sensor: 1, 2, 3, 4 Wire O2 Sensor Wiring Diagram Oxygen sensor also called O2 Sensor or lambda sensor (λ) is an electronic sensor that measures how many oxygen molecules are present in the exhaust gas, which helps the ECU monitor the engine performance. In this powerful guide, you will learn the wiring diagram of oxygen sensors such as 1... Oxygen Sensors Oxygen sensors are typically located in the exhaust manifold and/or exhaust system. While earlier fuel injection systems used one or possibly two oxygen Zirconia oxygen sensors can have one, two, three or four wires depending on the vehicle application. One or two wire O2 sensors are not... O2 Sensors/Oxygen Sensors Oxygen sensors measure the oxygen within the exhaust gasses to identify whether the combustion is lean/rich. Unfortunately the different manufacturers use different color wirings, and therefore the exact color of each wire has to be looked up in a wiring diagram in the workshop manual. 4 ...
