Does Corolla need to be equipped to change the throttle in 2004?

See what car throttle you changed, electronic throttle or general mechanical throttle? The mechanical throttle does not need to be matched, and it can be used directly by switching the ignition switch several times after replacement.

In general, the throttles of high-end cars are all electronic throttles, which must be matched after replacement. If it doesn't match, either it won't ignite, or the engine will shake, or it can't afford to refuel.

Especially for German cars, the requirements for throttle valves are quite high, and they cannot be used normally if they are not well matched. After the replacement, they must learn to match the computer before they can use it normally.

Some auto repairs can be matched without a computer, but the success rate is not very high and it is very troublesome. As for lighting the dashboard position for a few seconds, switching several times and stopping for a few seconds, it is basically impossible to succeed if the operation is not good.

So I suggest you use a decoding computer, click on the accelerator to learn directly after entering the system, and it will be done in a few seconds. If you don't have a computer, you can go to the repair shop and ask the people in the repair shop to help you learn. This is very simple. Ordinary repair shops will help you for free, just for one minute.
