Information - O2 sensor

The oxygen sensor is a measuring device that is able to assess the concentration level of the combustible mixture. It is in a state of active work as soon as it is warmed up to the desired temperature. Based on the readings of oxygen and other sensors, the car computer ensures better fuel economy, reduced exhaust toxicity and maximum power of the car engine.

To ensure an efficient economical and environmental performance of the internal combustion engine, the coefficient of air and fuel in the fuel-air mixture must be absolutely the same in all function modes. This can be achieved by using the oxygen sensor directly in the exhaust system. Thus, hydrocarbons and carbon monoxide are not fully oxidized because of the lack of air in the fuel-air mixture. On the other hand, when there is an excess of air, nitrogen oxides do not completely break down into nitrogen and oxygen.

Depending on the design, there are two types of oxygen sensors: two-point sensor and wide-band sensor. Productive work of the oxygen sensor is carried out at a temperature of 300 degrees.

What you need to know about lambda-sensor replacement: lifetime limits, common defects and their signs, tips and recommendations

Averagely, replacement of the lambda-sensor is required after 100 000 operational kilometers. Exploitation lifetime depends on the component type (especially, presence of the heater). If low-quality fuel is used, necessity of the O2 sensor replacement can appear earlier.

The following defects are the most common for the component: burning-out and soiling of the ceramic end, contacts oxidation, heater breakdown and depressurization of the sensor body.

Oxygen sensor defects are characterized by unstable engine work including working at idle, worsening of car dynamics, lowering of engine power and acceleration characteristics, increased fuel consumption, unusual noise after power plant turning on. If there is an indicator which controls work of the lambda-sensor, it will give an appropriate signal.

Diagnostics of the oxygen concentration sensor includes testing it with the help of the oscillograph. Results with voltage data are compared with the acceptable values specified by a manufacturer. It is recommended to contact a service station to check and replace the O2 sensor, because the procedure requires car repair experience and special equipment.

Advices for our customers

How do I check the lambda sensor?

To check if the lambda sensor is operable, you will need a multimeter. This procedure involves several stages. First, make sure that a sensor heater receives the voltage.

To do this, switch on the ignition and attach multimeter probes to the connectors of the wires going to the heater. Then carefully start the engine. Indicated voltage is supposed to be 12 V. Having unplugged the connector, attach probes to heater wires to test it. If there is no resistance, then the lambda sensor should be replaced.

Once the ignition is switched on, it is recommended to check whether there is reference voltage between the signal wire and chassis. The voltage should be 0,45 V. The lambda sensor signal is checked after the engine is heated up to the operating temperature. Voltage between the signal wire and chassis at 3 000 rev per minute is supposed to be between 0,1 - 0,9 V. Detailed instructions can be found in video tutorials.

Where do I install the lambda sensor?

The lambda sensor can be installed in different parts of the exhaust system. Two lambda sensors are usually used in modern vehicles: an upper sensor, installed in an exhaust manifold before a catalyst, and a lower one - placed after a catalyst.

The lambda sensor is sometimes installed in a headpipe before a catalyst. To detect this spare part exact location that depends on a vehicle design features, namely on an engine type, read the vehicle's technical documentation.

What are the lambda sensor fault symptoms?

Once the lambda sensor is faulty, it often causes other car systems to malfunction. Most common lambda sensor failure symptoms are:

  • increase of fuel consumption;
  • unstable motor operation;
  • vehicle jerking movements at driving;
  • increased toxicity level of exhaust gases;
  • unusual (popping) sounds produced by the power unit;
  • engine power reduction;
  • slow response when pressing the accelerator pedal;
  • black smoke coming out of the exhaust pipe;
