How to deal with the oxygen sensor


Oxygen sensor</a>

Combustion of fuel in the cylinders of engines is impossible without oxygen.

For its presence, a special device is monitored - an oxygen sensor (an oxygen sensor).

In the event of a malfunction in the engine, it is necessary to check its technical condition.

You will need

  • SRT, technical documentation for the car, diagnostic equipment.



We determine the deterioration of the car's acceleration dynamics by its own observations.


We establish the symptoms of such deterioration. If there are irregularities in the engine? Increased fuel consumption, or power drop, it is necessary to verify the performance of oxygen sensors responsible for the formation of a fuel-air mixture.


We conduct a visual inspection of the power unit. On modern models of cars, oxygen sensors are not less than two. We check the connection of the wires by probing the terminals on the sensor located on the intake manifold through the rubber boot.


Similarly, we check the wiring of the second oxygen sensor located in the area of ​​the exhaust system.


We check with the help of measuring equipment forSTO the status of oxygen sensors. It should be remembered that they can not be repaired. If the sensor does not match the operating parameters? It should be replaced. Other options are not provided by the manufacturer.
