The oxygen sensor is a key component of the car’s emission control system. It monitors the amount of oxygen in the exhaust gas and adjusts the air/fuel mixture to ensure that the engine runs at peak efficiency. A properly functioning oxygen sensor can help improve fuel economy and reduce emissions.
If your car is shaking, it could be a sign of a bad O2 sensor. Here’s what you need to know about this problem and how to fix it.
Can A Bad O2 Sensor Cause Shaking
If one of the O2 sensors fails, the engine may be misfuelling, causing the vehicle to shake as it drives away. An OBD2 diagnostic tool, which can view live data as the sensors work and check for fault codes within the ECU, is typically used to detect this type of fault.
The O2 (oxygen) sensor is located in the exhaust system of the vehicle. Two sensors, one pre-catalytic converter, and one post-catalytic converter will be found in some models. These sensors will regulate the amount of fuel pumped into your engine at any given time, based on whether your engine is running too lean or too rich.
While driving, a defective O2 sensor can undoubtedly create shaking or vibrations in a car. When the O2 sensor fails, it creates an incorrect air-to-fuel mixture in the combustion chambers, causing the engine to shake. These vibrations can be felt in the vehicle’s cabin while driving.
The replacement of the O2 sensor may help to lessen engine vibrations, but if the steering wheel shakes it’s most likely due to worn brakes, wheel bearings, or other front-end components.
In conclusion, a bad O2 sensor can cause shaking, but it is not the only possible cause. There are several other potential causes that should be considered as well. If your car is shaking, it is best to take it to a mechanic to have it checked out.
