Oxygen Sensor A0075426318 For Mercedes W246 X156

Automobile oxygen sensor is one of the most important sensors in the engine control system. If it is damaged or fails, it may lead to the following common problems:

1. Engine performance degradation: The damaged oxygen sensor can't accurately measure the oxygen content in the exhaust gas, resulting in the engine control system can't correctly adjust the fuel mixture ratio. This may lead to engine performance degradation, such as poor acceleration and insufficient power.

2. Decline in fuel economy: Damage to the oxygen sensor will lead to a decrease in engine combustion efficiency and incorrect fuel mixing ratio, which will lead to a decrease in fuel economy and an increase in vehicle fuel consumption.

3. Excessive exhaust emission: Damage to the oxygen sensor will lead to incomplete combustion of the engine, and the emission of harmful gases in the exhaust gas will increase, which may lead to excessive exhaust emission of vehicles, which does not meet the requirements of environmental protection.

4. Unstable engine operation: The damaged oxygen sensor will lead to unstable engine operation, which may lead to unstable idle speed, jitter, fire and other phenomena.

5. The detection light is on: When the oxygen sensor is damaged, the Check Engine Light of the vehicle may be on, prompting the driver that there is a problem and it needs to be repaired in time.

Generally speaking, the damage of automobile oxygen sensor may lead to engine performance degradation, fuel economy degradation, excessive exhaust emission, unstable engine operation and lighting of detection lights. Therefore, once the oxygen sensor is found to be faulty, it should be repaired or replaced in time to ensure the normal operation of the engine and the exhaust emission meet the environmental protection standards.
