What is deceleration fuel cut off?
Deceleration fuel cut-off is a system that automatically cuts the fuel supply when coasting or braking in order to achieve better fuel efficiency and more effective engine braking, and resumes fuel supply when acceleration is once again needed.
What does fuel cut off valve do?
Not only does shutting off the fuel valve prevent the engine from flooding while being transported, it prevents flooding because of contamination in the float valve, and extends the life of the float valve by decreasing pressure on it.
What is DFCO cars?
I know that it stands for Deceleration Fuel Cut Off and I also know that most modern vehicles including my Scion employs it because I see it on my scangauge.
Where is the fuel pump shut off switch?
Once the vehicle determines the systems are safe, then the vehicle allows you to restart. The fuel pump shut-off switch is located behind an access panel on the right side of the luggage compartment. The fuel pump shut-off switch has a red reset button on top of it.
What is the purpose of having an electronic sensor inside a fuel tank that is attached to a fuel pump’s automatic shut off valve?
The fuel tank pressure sensor is part of the fuel pump assembly and is mounted on top of the tank or inside the tank. It’s part of the evaporative emissions system (commonly referred to as “EVAP”) and reads pressure in the fuel system to detect evaporative leaks, such as a loose or faulty gas cap.

What is Dfco tuning?
DFCO is Deceleration Fuel Cut-off and it basically does just that , it cuts the fuel off while you decelerate with you’re foot off the gas pedal when you are over a a pre determined speed and rpm . This gives you better fuel economy.
What is a FTP sensor?
How do I disable HP Dfco tuners?
Leave the Fuel Cut Enable alone, and change the enable/disable temps to something like 490/489 and/or the enable/disable rpm to something like 8000/7900. That will eliminate DFCO and keep your rev limiter.
What is an inertia switch do?
In case you don’t know the inertia switch, it is designed to shutoff the fuel pump in the event of a collision, as to not create a fire hazard if a fuel line is damaged. Inertia from a crash was used to trigger the switch.
What causes fuel solenoid failure?
The Advance actuator solenoid generally fails as a result of contamination within the fuel system. This will often cause the following symptoms. These problems can be caused by the incorrect operation of the advance actuator which becomes stuck in an open or closed position.
