Oxygen Sensor 11787537993 For BMW E63 E64 E60

There may be a variety of problems in the use of automobile oxygen sensors, including the following common situations:

1. Pollution: The oxygen sensor will be affected by pollutants in the engine exhaust gas during long-term use, which will lead to the accumulation of carbon or other impurities on the surface of the sensor element and affect the sensitivity and accuracy of the sensor.

2. Wear: The service life of the oxygen sensor is limited, and wear will occur after long-term use, which will lead to the decline of the sensor performance and make it impossible to accurately monitor the oxygen content in the exhaust gas.

3. Fault: The oxygen sensor may fail due to circuit fault, connection problem or sensor element damage, which will cause the engine control system to fail to work normally and affect the combustion efficiency and emission performance of the engine.

4. Delayed response: The response speed of the oxygen sensor may slow down during the working process, which leads to the sensor's failure to monitor and adjust the fuel supply in time and affects the combustion efficiency and performance of the engine.

5. Wrong reading: The oxygen sensor may have wrong reading in the working process, which will lead to the misjudgment of fuel supply by the engine control system and affect the working state and performance of the engine.

The above problems may lead to unstable engine operation, increased fuel consumption, excessive exhaust gas, etc. Therefore, it is suggested that the owner regularly check the working state of the oxygen sensor and replace the aged or damaged oxygen sensor in time to ensure the normal operation and emission performance of the engine.
