Which Fuse to Remove for Toyota Throttle Body Matching Method?
2 Answers
Remove the fuse located next to the battery and air filter. Matching method: Turn the key to the second position (ignition on), all dashboard indicators will light up in the first position, wait for 20 seconds, then press the accelerator pedal fully and hold for about 10 seconds, release the accelerator, turn off the ignition switch, and remove the key to complete the initialization. Below is some introduction about the throttle body: 1. The throttle body is a controllable valve that regulates air intake into the engine. After entering the intake pipe, the air mixes with gasoline to form a combustible mixture, which then ignites to produce power. 2. The throttle body is one of the most important components in the fuel-injected engine system. Its upper part connects to the air filter grid, and the lower part connects to the engine block, serving as the throat of the car engine. The responsiveness of acceleration is closely related to the cleanliness of the throttle body. Cleaning the throttle body can reduce fuel consumption and make the engine more responsive and powerful.
When I previously encountered throttle body issues, I actually researched the matching methods for Toyota vehicles. Generally speaking, you need to pull either the EFI (Electronic Fuel Injection system) or the ENGINE main fuse. Not to scare you, but the fuse locations vary significantly across different Toyota models. For example, with a Camry, you typically pull the EFI fuse from the engine compartment fuse box and wait 30 seconds to allow the ECU to fully reset. My old Corolla required pulling the ECU fuse from the fuse box under the driver’s seat. After completing the matching process, remember not to press the accelerator when starting the engine—let it self-learn for a few minutes to avoid unstable idle. Beginners should consult the specific model’s repair manual before attempting this. Nowadays, many forums even share photos of the fuse box covers for reference.
