What is the throttle matching method for Corolla?

Open the fuse box cover and you can see the instructions on the back of the cover, then pull out the fuse. First, keep the engine in the ignition state (remember this point clearly, it must be in the ignition state). Pull out the ETCS fuse, and the engine will immediately shut down passively. Pull out the EFI fuse, do not turn off the ignition, and wait for 30 seconds.
I've been in car repair for over ten years and have encountered the Corolla throttle body matching process many times. The manual method is quite simple: stop the car and turn off the engine, press the accelerator pedal all the way down and hold for 5 seconds, then turn the key to the ON position without starting the engine, wait for the dashboard lights to go off for about 5 minutes and it's done. If you find it troublesome, buying an OBD scanner and using computer software for one-click initialization is more convenient. The key point is to perform the matching immediately after cleaning the throttle body or replacing the battery, otherwise the idle speed may fluctuate or even stall. Related to this, the throttle body should be cleaned regularly to avoid clogging, as incorrect matching can easily damage the sensor. It's recommended to go to a professional repair shop for testing, as their professional tools can reduce risks. If you DIY, pay attention to power-off safety to prevent short circuits and unnecessary expenses.
Hey, I'm a DIY car enthusiast. Last year, I had a blast matching the throttle on my Corolla. Method one: Park the car, start the ignition without pressing the accelerator, and let it sit for ten minutes—the system resets automatically, super easy. Method two: Turn off the engine, turn the key to the on position, press the accelerator for three seconds, then release—you'll hear a beep indicating completion. It's best to disconnect the negative battery cable first to prevent electric shock—safety first. When I didn't match it properly, the idle speed went crazy and almost damaged the engine—I learned the hard way. After cleaning, I forgot to match it and nearly stalled, but luckily restarting fixed it. I recommend beginners start with the simple manual method—just use the car key, no need for complex tools. It's cost-effective and practical. Related tip: Regularly check the throttle condition to keep the matching smooth, which can improve fuel efficiency and make long drives smoother.
