Saturn L300 Oxygen Sensor
Common Concerns with the Saturn L300 Oxygen Sensor
Designed to detect if the mixture of air and gasoline going into your car's engine is either rich or lean, the Saturn L300's oxygen sensor helps your engine perform efficiently while producing better emissions. Oxygen sensors work hand-in-hand with your car's ECU and, if the sensors detect a problem with the fuel and air mixture, the ECU will automatically adjust the mixture before it enters the engine. But if the oxygen sensor fails, the ECU won't be able to determine the correct fuel and air ratio. This leads to poor engine performance and higher fuel consumption. Once these concerns arise, it's time to do some troubleshooting. Here are some common oxygen sensor concerns encountered by Saturn L300 owners, and the possible factors behind them:
Oxygen sensors can control some of your car's engine functions. These functions range from engine combustion intervals, engine timing, and most especially the fuel and air mixture entering the combustion chamber. Now, if the oxygen sensor fails, it will start to disrupt these processes and the engine will run roughly. When this concern arises, check your car's oxygen sensor for any signs of damage or contamination. If the sensor is already damaged, purchase a new one, and replace it immediately.
If your car's engine starts to miss or choke at times, it could be due to a malfunctioning oxygen sensor. Since this sensor regulates the engine's air and fuel mixture, and carbon deposits can build up in the sensor which affects the engine's normal combustion. You can remove the oxygen sensor and clean it with gasoline. This will remove sulfur, carbon, and other deposits from it.
Increase in fuel consumption and emissions
A malfunctioning oxygen sensor will affect the engine's fuel delivery and combustion system. More fuel is pumped into the engine's combustion chamber, resulting in an increase in fuel consumption. Also, since the oxygen sensor is unable to accurately measure the engine's air/fuel mixture, this leads to an increase in vehicle emissions. Nitrogen-oxide rich pollutants are now released into the atmosphere. It's better to replace your car's oxygen sensor with a new one to improve its emissions and restore proper fuel consumption.
