How to match the throttle of a 2005 Teana V6?

After turning off the car, turn the ignition switch to ON. Wait for about 3 seconds, then quickly press the accelerator pedal and ensure to release it 5 times within 5 seconds. Then wait for about 7 seconds without moving anything. Press the accelerator pedal again and hold it for about 10 seconds. The engine warning light on the dashboard will flash and then stay lit. At this point, the throttle matching is complete, and you can release the accelerator pedal. Pay attention to the timing during the matching process. If it doesn't succeed the first time, try again.
I'm quite familiar with the maintenance of older Nissan models. For the 2005 Teana V6, the key to throttle body matching is to let the ECU relearn the position, especially after cleaning or replacement. I'd recommend a few methods: first, disconnect the battery negative terminal for about 10 minutes and then reconnect it, followed by starting the engine and letting it idle for 5 minutes to allow automatic adaptation; second, using an OBD-II scanner to connect to the engine system and perform a clear adaptation values operation is more precise. Personally, I've used both methods – manually disconnecting the battery is suitable when you don't have tools, but it might not be thorough; the scanner is more reliable, especially since you can find Nissan-specific tutorials online. Poor matching may lead to idle vibration or increased fuel consumption, so I always check if the engine runs smoothly after each maintenance. For older cars like the Teana, the ECU is quite sensitive, and a test drive of a few kilometers after matching can verify the results.
