Saturn Vue Fuel Tank Cap
How to Tell if Your Saturn Vue Fuel Tank Cap is Failing
Your Saturn Vue fuel tank cap is just a small piece of device, yet it does a huge amount of service. When it becomes severely damaged, your car may suffer from poor performance and low gas mileage. That's why it is very important to pay close attention to this component and observe its condition every once in a while. When it starts to show some symptoms of failure, get ready to perform some of these troubleshooting steps.
The easiest way to diagnose tank-cap-related problems is by plugging your automotive scan tool. This electronic device has the ability to detect current problems in your vehicle. Simply plug this tool to the outlet found under the dash. Wait for a few minutes to allow the scanner process the data. When you see the error code "Po44o," it means that your fuel tank cap is loose. But this isn't the only code that tells you you're having a problem with your cap. There are other codes to watch out for that may indicate more serious problems like broken gas seals and gas leaks. Therefore, you should not stop there. Continue with the other troubleshooting steps.
The prevalent smell of gasoline is perhaps the most obvious sign of tank cap failure. It happens when the cap goes completely missing or when the tank seal becomes torn. In this case, you need to pop the hood open to take a closer look at the fuel tank. Remove the cap and inspect it for physical damage such as cracks and dents. Put the cap back and make sure that it is tight and sealed. If you can still smell gasoline, it means that your cap is broken, hence must be replaced immediately.
Poor gas mileage
Gasoline easily turns into gas because it is a highly volatile substance. When you see that your cap is full of holes and cracks, you are at risk for poor gas mileage. Gasoline can escape into the atmosphere if the cap is damaged. Because of that, you'll experience a sudden decrease in your fuel. If you keep on experiencing this even if you haven't changed any of your driving habits, it's high time to replace your fuel tank cap.
