How to Match the Throttle Body on a Toyota Corolla?

Turn the key to the second position, which is the position where all dashboard indicators light up. Then wait for 20 seconds and fully depress the accelerator pedal. Keep the key in this position for about 10 seconds, then release the accelerator pedal. Turn off the ignition switch, remove the key, and the initialization is complete.

I remember helping a friend with the throttle body adaptation for his Toyota Corolla when he replaced it himself and experienced unstable idle. The main steps were: first, turn off the engine, disconnect the battery negative terminal and wait for 5 minutes to allow the ECU to fully reset. Then reconnect the battery, sit in the driver's seat, turn the ignition to ON without starting the car, press the accelerator pedal all the way down and hold for 5 seconds, then release it completely. Finally, start the engine and let the car idle in neutral for about 10 minutes, allowing the ECU to automatically learn the new throttle position. If this step is skipped, acceleration may feel jerky or idle vibration may increase. It's recommended to use a diagnostic scanner to check for trouble codes after completing the procedure, just in case. Regular throttle body maintenance can also help reduce such issues.
