The oxygen sensor is a crucial component in a car's emission control system. It is one of the many sensors that the computer relies upon to determine the operating condition of the car and to make constant adjustments for peak performance. The sensor examines the exhaust gasses emitted by your engine and gauges the amount of oxygen they contain. If the gasses contain a high percentage of oxygen, the engine is running lean. If the percentage is low, the engine is running rich. The computer controlling the engine will adjust the fuel mixture and ignition timing based upon the measurements it receives from the O2 sensor. As the adjustment is made, the O2 sensor reads the results of the change in the exhaust stream and returns the new measurements. This closed-loop system is constantly adjusting the mixture, so that your car runs at its best.
Rough Engine Idle
- Vehicle engines that have a bad oxygen sensor often run irregularly or roughly. Oxygen sensors can control or contribute to many different engine functions, including fuel/air mixture, engine timing and engine combustion intervals. A faulty oxygen sensor can disrupt any of these things and cause a rough engine idle.
- A bad oxygen sensor can impede the air/fuel mixture of an engine or interfere with the engine combustion, both of which can cause an engine to miss, or run irregularly. An engine miss is normally most pronounced at idle or at lower engine speeds; a faulty oxygen sensor can inhibit the normal fuel delivery/combustion within an engine and cause a miss.
- If a bad oxygen sensor is aligned with the ignition system on a car's engine, it can retard or advance engine ignition timing, which can cause an engine to ping. Pinging occurs when an engine's combustion gases are ignited at the wrong times.
Poor Gas Mileage
- Depending on the type and/or location of a faulty oxygen sensor, the fuel-delivery and the fuel-combustion systems can be thrown off or made irregular by a faulty oxygen sensor. If too much fuel is injected into an engine's cylinders or a faulty oxygen sensor disturbs the delicate air/fuel mixture of an engine, gas mileage will suffer.
Increased Vehicle Emissions
- Vehicle oxygen sensors play a critical part in keeping a vehicle's emissions within certain parameters. A vehicle can fail a state-mandated smog test because a bad, or faulty, oxygen sensor will not accurately measure various engine ratios or air/fuel mixture concentrations or adjust certain engine operations accurately enough to keep a vehicle's emissions in check.

O2 Sensor / Lambda Sensor
Food for Thought
An oxygen sensor (or lambda sensor) is an electronic device that measures the proportion of oxygen (O2) in the gas or liquid being analyzed.
It was developed by the Robert Bosch GmbH company during the late 1960s under the supervision of Dr. Günter Bauman. The original sensing element is made with a thimble-shaped zirconia ceramic coated on both the exhaust and reference sides with a thin layer of platinum and comes in both heated and unheated forms. The planar-style sensor entered the market in 1998 (also pioneered by Bosch) and significantly reduced the mass of the ceramic sensing element as well as incorporating the heater within the ceramic structure. This resulted in a sensor that started sooner and responded faster.
The most common application is to measure the exhaust gas concentration of oxygen for internal combustion engines in automobiles and other vehicles. Divers also use a similar device to measure the partial pressure of oxygen in their breathing gas.
Scientists use oxygen sensors to measure respiration or production of oxygen and use a different approach. Oxygen sensors are used in oxygen analyzers which find a lot of use in medical applications such as anesthesia monitors, respirators and oxygen concentrators..
Oxygen sensors are also used in hypoxic air fire prevention systems to monitor continuously the oxygen concentration inside the protected volumes.
There are many different ways of measuring oxygen and these include technologies such as zirconia, electrochemical (also known as Galvanic), infrared, ultrasonic and very recently laser methods. Each method has its own advantages and disadvantages.
