How To Tell Which O2 Sensor Is Bad + 4 wire o2 sensor wiring diagram Knowing which of the upstream or downstream oxygen sensors is going bad is the same as understanding which O2 sensor is bad. In case your mileage is going bad, this simply means your fuel trims are putting in lots of gas and haven't been updated in a while.

The diagram will show the location of the oxygen sensor, the type of sensor, and the color of the wires. The diagram may also show the location of other sensors and components that are related to the oxygen sensor. In this powerful guide, you will learn the wiring diagram of oxygen sensors such as 1, 2, 3, and four-wire o2 sensor wiring schematic.
[DIAGRAM] Wiring Diagram O2 Sensor
The four wires in the oxygen sensor diagram correspond to the signal wire, the ground wire, and two reference voltage wires. The signal wire carries the voltage signal generated by the sensor, which provides information about the oxygen content to the ECU.
Oxygen Sensor in Canada TheWrenchMonkey Canada
The wiring diagram for a 4 wire oxygen sensor includes four wires: two for the oxygen sensor signal and two for the sensor's heater circuit. The oxygen sensor signal wires are responsible for transmitting the voltage signal produced by the sensor to the engine control module (ECM).
Faulty Oxygen Sensor O2 Symptoms & Diagnosis
The wiring diagram in Figure 6 is typical of what you may see in service information, please note that there are six wires shown in the diagram. There will be a total of six wires on the ECM side of the circuit but only five wires on the actual Bosch wide range oxygen sensor. If you look closely at the Bosch wiring diagram above and follow the trim resistor circuit, it will offer some insight.

An oxygen sensor (or lambda sensor, where lambda refers to air-fuel equivalence ratio, usually denoted by λ) or probe or sond, is an electronic device that measures the proportion of oxygen (O 2) in the gas or liquid being analysed. It was developed by Robert Bosch GmbH during the late 1960s under the supervision of Günter Bauman.

1 Answer Sorted by: 16 No, you don't have to rely on wire colors to figure out what's what. With nothing more than a decent multimeter and premix flame (blowtorch or gas stove), a two-test sequence can reveal the identity of each wire, assuming the O2 sensor is fully-functional: Determine the heater wires This should be done first.

Each sensor has two-feet length of sensor wire to allow maximum replacement of worn harnesses.
Oxygen Sensor History Walker Products
The 1st sensor is located closest to the engine, and the last is located toward the rear of the exhaust system. Generally, if we are talking about O2 sensors: Sensor 1 = Before Catalytic converter Front (Upstream O2 sensor) Sensor 2 = After Catalytic Converter Rear (Downstream O2 sensor) Some diesel engines have many exhaust temperature sensors.
