Fit EC0 is not on. What's wrong with the fault light?

This phenomenon is normal in Pacific Auto Network, because when switching to ECO energy-saving driving mode, the computer will first light the ECO light on the dashboard to remind the driver to be in energy-saving mode at this time. The fault light is turned on because the engine system is not working well, such as the fault of accelerator pedal sensor, throttle position sensor, air flow meter and crankshaft position sensor or poor line contact, which will lead to the engine fault light being turned on.

Then the computer will change a series of settings, such as reducing the fuel injection to match the thinner combustible mixture, such as changing the shift logic of the transmission, which will become more active.

That is to say, in this mode, everything is aimed at "saving fuel", so in the energy-saving mode, you will obviously feel that the power is getting worse and it is more fleshy to drive. To put it bluntly, it is unrealistic to think that horses can run fast without eating grass. However, in the actual driving process, even if the driving wind is not very strong for the grid, drivers will often encounter some situations that need rapid acceleration, such as overtaking large trucks in the same direction. The sooner you overtake at this time, the safer it will be, so it is generally safe. If you are in energy-saving mode at this time, the acceleration performance of meat is obviously not ideal. In this case, the computer can identify the driver's intention through the action of the accelerator pedal, and then make timely responses in control, such as increasing fuel injection and downshifting. At the same time, the computer will control the ECO light on the dashboard to go out, reminding the driver that he is not in the energy-saving mode at this time. Simply put, as long as the car is under heavy load, the computer will automatically cancel the energy-saving mode and turn off the ECO light, such as high speed and climbing. Next,
