Lambda Sensor

Lambda sensor is used in cars to measure the amount of residual oxygen in the exhaust. This value is used for optimization of fuel mix, in particular for controlling the ratio of fuel and air. At the optimum ratio most of the pollutants in the catalyst can be transformed into harmless substances. There are lambda sensors that react to jumps of resistance, of tension and broadband lambda sensors. Along with the oxygen content in exhaust gases, oxygen content in ambient air is also measured.

If the oxygen sensor is faulty, indexes of the exhaust gases are deteriorating. Control of exhaust emissions will help to identify the problem. Significant reduction of power during acceleration may also indicate a faulty oxygen sensor. Black smoke from the exhaust pipe is one of the signs that the lambda sensor has failed. Before dismantling check if the wire is in place. In modern cars information about lambda sensor functioning is displayed on the dashboard. The oxygen sensor cannot be repaired, it must be completely replaced. It is easy to replace the sensor and you can do it without any assistance.

The oxygen sensor is located between the catalyst and the exhaust manifold. The old tube is unscrewed and replaced by a new one. The presence of the inspection pit hastens the repair. After installation verify the exhaust value and analyse the indicators on the dashboard. Our online store offers you a wide assortment of car parts.
