These codes can help a mechanic identify the issue and determine the most effective course of action. For instance, the check engine light might be a sign of a problem with the circuit that controls the fuel level. It could also signal an issue with the emissions idle control system. In other instances the light could be an indication of something more serious, such as a loose gas cap.
Certain codes could be serious and require immediate repair. If you have more than one DTC in your vehicle, it's important to determine which one is more serious and urgent to fix.
Checking fuel supply
Fuel pressure and volume can be an important element of vehicle diagnostics. A fuel pump that is not working properly could cause trouble codes to show on your vehicle's computer. You can decode these codes with the code reader or scan tool. Many auto parts stores offer code reading services at no charge. You can also purchase inexpensive code reading devices for your smartphone. Once you have an idea of what to look for you can test the fuel pressure.
Monitoring the fuel supply is a simple procedure. It's easy to follow. Listen for a hum in the fuel tank to check it. It should last for around two seconds before it stops. If you hear a humming sound it is a sign that your fuel pump's electrical circuit is functioning properly. If not, it is time to perform further tests to determine the cause.
You can also test the fuel pressure as well as the MAF sensor for fuel leaks. The P0171/P0174 codes can be due to an MAF sensor that is dirty. If you're unsure of which part you should replace you can consult an efficiency chart for volumetric measurements or calculator to determine which one.
