5 Symptoms Of A Malfunction Oxygen Sensor in the Car Some Car Owners Don’t Realize

The oxygen sensor in the car has a role to check the ratio of air and gasoline. Then, the system in the car can adjust it if needed. The oxygen sensor shows the amount of oxygen in the exhaust gasses that exit the engine. A malfunctioning oxygen sensor in the car affects the combustion intervals, engine’s taming, and slow acceleration. Learn symptoms of a malfunction oxygen sensor in the car below, so you can handle it right away. 

1- A Signal from the Check Engine Light 

Check engine light often gives you a sign if there is a problem with your vehicle, including a malfunctioning oxygen sensor. The check engine light turns to bright orange when a vehicle has a bad oxygen sensor. Only because the light turns on doesn’t mean that it is always a bad oxygen sensor. It can cause other engine or gas cap problems. Bring the vehicle to a reputable dealer or mechanic when you see the check engine light turn on to ensure what the problem is. 

2- Check the Fuel 

The oxygen sensor in the car detects the oxygen level after the combustion engine process. The sensor tracks the oxygen level in these exhaust gases as the gases leave the engine. This feature sends the information back to the engine control module. Then, the computer system communicates it with a variety of sensors in the car. So, what happens when there is a problem with the oxygen sensor? It means that this feature can’t detect the air and fuel mixture in the combustion cylinders. As a result, there will be more fuel being burned in the engine. You have to spend more money on gas because of a bad fuel economy. It is considered one of the common symptoms of a malfunction oxygen sensor in the car. 

3- Unsteady Running 

Call a mechanic right away if your vehicle is unsteady anytime you stop or park it. This condition may happen because the engine RPM increases significantly up to 2.000 or even 3.000. A normal RPM engine is under 1.000. The main cause is that your car can’t control the oxygen level because the engine control module is hard to manage. As a result, the engine timing will be more difficult. The car will have combustion intervals that cause misfires.      

4- Weak Engine Performance 

Weakened engine performance or car losing power is another symptom of a malfunctioning oxygen sensor in the car. It happens even if the combustion process in the engine is normal. Find out by stepping on the gas pedal. Then, feel the acceleration. A car with a malfunctioning oxygen sensor will have a limited or even nonexistent acceleration. 

5- Failed Emissions Test 

Cars with a bad oxygen sensor have failed in emission tests. It is because the sensor doesn’t work well and the location is in the manifold of the exhaust system. Emission test failure is not necessarily because of a bad oxygen sensor. It can also be because of other issues. Because of that, bring the vehicle to a mechanic to know the exact problem. Do it right away once you feel the symptoms of a malfunction oxygen sensor in the car.
