Why is the O2 sensor on my Chevy Malibu bad?

By using a OBDII scanner you can determine exactly which sensor is bad, and what is wrong with it. Your Malibu’s oxygen sensors are responsible for helping to keep your engine running at optimal efficiency. The engine management computer uses the data from all of the O2 sensors to keep the air/fuel mixture optimized.

Why does the Check Engine light come on on a Chevy Malibu?

Oxygen sensors can change the way that your Malibu’s engine runs. Most of the time, the check engine light will come on. It’s a good thing that the check engine light would come on, as there is more than one oxygen sensor, and they can be difficult to get to and test.

Symptoms of a Bad or Failing Oxygen Sensor 1 Check Engine Light comes on The first line of defense is the Check Engine Light. 2 Bad gas mileage and rotten egg smell If the oxygen sensor is going bad, the fuel-delivery and fuel-combustion systems will be thrown off. 3 Rough engine idle and misfires

What happens when you change the O2 sensor?

The O2 sensor then sends information to the electronic control unit, or ECU, the vehicle’s computer. The ECU then adjusts the air-to-fuel ratio to optimize the fuel combustion. Sometimes an O2 sensor fails, and you need to replace it.

What are the symptoms of an oxygen sensor going bad?

One of the most common symptoms that an oxygen sensor has gone bad is exhaust that does not smell good. The smell is often described as “rotten eggs” or sulfuric.

What does the O2 sensor on my car do?

Touch device users, explore by touch or with swipe gestures. Your oxygen sensor, sometimes called an O2 sensor or air-fuel ratio sensor, measures the oxygen level in your exhaust gases. It then relays this information to the ECU to adjust the fuel mixture.

How does the O2 sensor in a car work?

The O2 sensor in your vehicle monitors the exhaust gases coming out of the engine. It determines the amount of oxygen in the gases, which indicates how well the fuel is being burned. The O2 sensor then sends information to the electronic control unit, or ECU, the vehicle’s computer.

When to reset the ECU after changing an O2 sensor?

Sometimes an O2 sensor fails, and you need to replace it. Once you’ve replaced your vehicle’s O2 sensor, you’ll need to reset the ECU so it can properly gather information from the new O2 sensor.
