Cleaning the Throttle Body via Self-Learning

Model: Mazda 3 MK 1, BK - Years 2003-2009
Part: Throttle body

This guide shows how, in this specific case, cleaning the throttle body can be done through a procedure called self-learning. It is a fairly simple procedure to execute and does not require much time. Simply turn on the ignition with all devices possibly turned off and wait a few seconds. When you turn on the ignition, the throttle plate moves. This procedure calibrates it. The procedure lasts approximately fifteen minutes during which you must not touch the key or open the doors. Once this operation is complete, you can turn off the ignition, wait to hear the relay click, and then start the engine.
