Product Description
1. Front oxygen sensor failure:
-engine performance degradation: the failure of the front oxygen sensor will cause the engine control system to fail to accurately monitor the oxygen content in the combustion chamber, which may lead to incomplete combustion or incorrect fuel mixing ratio, thus reducing engine performance and fuel economy.
-Unstable idle speed: The failure of the front oxygen sensor may lead to unstable idle speed of the engine, even jitter or flameout.
-High emission: Due to the decrease of combustion efficiency, the failure of the front oxygen sensor may lead to the increase of harmful gas content in the exhaust gas, which exceeds the environmental protection standard.
2. Failure of rear oxygen sensor:
-Excessive exhaust emission: The failure of the rear oxygen sensor will cause the vehicle to fail to accurately monitor the oxygen content in the exhaust emission, which may lead to excessive exhaust emission and failure to pass the emission test.
-engine performance degradation: the failure of the post-oxygen sensor may cause the engine control system to be unable to accurately adjust the fuel mixture ratio, which will affect the combustion efficiency and performance.
-Increased fuel consumption: Failure of the rear oxygen sensor may lead to decreased combustion efficiency and incorrect fuel mixing ratio, which may lead to increased fuel consumption.
Generally speaking, the failure of the front oxygen sensor may lead to engine performance degradation, unstable idle speed and high emissions; Failure of the rear oxygen sensor may lead to excessive exhaust emission, engine performance degradation and fuel consumption increase. Therefore, timely maintenance and replacement of faulty oxygen sensors are very important for vehicle performance and environmental protection emissions.
