Saturn Sky Oxygen Sensor
Bad Saturn Sky Oxygen Sensor Signs and Symptoms
The oxygen sensor is basically in charge of monitoring the amount of oxygen in the exhaust gases on your engine. This helps the vehicle computer adjust the right mixture of air and fuel to improve the performance of the car and make your driving experience a great one. However, it's also quite inevitable for this to get busted over time. So, it's good to know whether or not it's about to go south so that you can do corrective action as soon as possible. Here are some of the symptoms to know if the Saturn Sky oxygen sensor is defective.
Increased car emissions
Since the oxygen sensor adjusts the amount of air and fuel mixture, driving with a busted one can surely increase the emissions that your car does. It can result in bad fuel and air combination or rich or lean fuel-injection delivery. These cause inappropriate and inefficient engine combustion and will surely let out more emissions that are usual.
Whenever you step on the accelerator and you feel that there is engine hesitation, it can be due to an oxygen sensor that was misinterpreted. This results to the misreading of the engine's mixture of fuel and air or the right amount that is required, which can cause little or too much air and fuel to enter the cylinders of the engine. Hence, the car engine experiences hesitation or stumbling.
Low gas mileage
If your car has poor gas mileage, then this means that it is not getting the right mixture of air and fuel. Basically, the oxygen sensor adjusts the ratio of these two so that the engine would have enough of these to produce power. If the sensor becomes defective, too much fuel would be added to ratio that is needed, which then results to low gas mileage.
Irregular engine idle
If you start experiencing rough engine idles, it's an indication that there's something wrong with the oxygen sensor. A defective one can make the engine idle in a rough way. This usually happens when the engine combustion receives not-so-good firings, which lead to very poor engine performance.
