Magton B7 2.0T Oxygen Sensor Fault Diagnosis and Troubleshooting
Magton B7 2.0T Fault Light of vehicle engine gives an alarm,hot car is not easy to start.In this paper,the fault phenomenon is diagnosed and analyzed,it is caused by the poor working of the oxygen sensor.The oxygen sen-sor detects the oxygen content in the exhaust gas and converts it into an electrical signal.The PCM controls the air-fuel ratio to maintain it near the theoretical value,achieving a closed-loop air-fuel ratio control to ensure that the three-way catalytic converter operates at its highest efficiency,resulting in the engine achieving the best emission performance.This paper introduces the installation position,type,structure and working principle of the oxygen sensor used in Magton B72.0T vehicle and provides ideas and methods for fault diagnosis and troubleshooting.
