Old corolla throttle matching

Matching the throttle of the old Corolla is easy. Just turn the ignition key to the second gear, wait for about 20 seconds, press the accelerator pedal to the bottom 10 second, and then turn off the ignition switch.

Throttle is the key component of engine. The throttle is called the throat of the engine. Throttle can control the amount of air entering the engine.

After we step on the accelerator pedal, we actually control the throttle opening, not directly control the fuel injection.

When the accelerator pedal is depressed, the throttle opening will increase, so more air will enter the engine, and then the ecu will command the fuel injection system to inject more fuel.

If the throttle valve is used for a long time, there will be carbon deposition. If there is carbon deposit on the throttle surface, it needs to be cleaned.

Cleaning the carbon deposit on the accelerator is simple. Just remove the throttle valve and clean it with professional cleaning agent.

After cleaning up the accelerator deposit, you should reconfigure the computer, otherwise the fuel consumption of the car will increase in a short time.

Ecu has a strong learning ability, and will use another set of control logic to control the throttle with carbon deposit after detecting the carbon deposit in the throttle.

After the carbon deposit on the throttle is removed, ecu will continue to use the control logic with carbon deposit to control the throttle without carbon deposit, which will lead to an increase in fuel consumption.
