What happens when you lift off the gas pedal?
The APP sensor essentially tells your engine how fast or slow to drive when you press the gas pedal. When you press down or lift off the throttle, it sends an electrical signal to the vehicle’s engine control unit (ECU), and then transmits that signal to the fuel system.
What happens when you depress the accellerator pedal?

Why does my car not start when I take my foot off the gas?
The fuel injectors work at any RPM, so a choke is not necessary. The computer simply feeds a little extra gas through the fuel injectors to start the engine. On the old carburetor engines, you pressed the gas pedal before starting to set the choke position and give a squirt of fuel into the engine via the accelerator pump.

Why does my car not respond to the gas pedal?
Electronic throttle controls module faults are one of the most common issues when dealing with a unresponsive gas pedal. This is a sensor that reads how far you have pressed the gas pedal down and outputs that information to the computer which controls the throttle. This information is also used in computing ignition timing and other components.

What to do if your gas pump won’t turn on?
A driver can press the gas pedal, and all of the throttle components may be demanding the correct amount of fuel, but the pump is facing resistance at the filter and cannot allow the flow to go through to the engine. If the fuel filter is clogged, the only repair that can be made is to replace the filter.
