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.
I've driven similar cars before, and I prefer a simpler approach when matching the throttle. For the 2005 Teana V6, disconnecting the battery for a few minutes is the most straightforward method: turn off the engine, unscrew the negative battery terminal clamp, wait 8-10 minutes, then reconnect it, turn the key to start the car and let it idle for a few minutes. The ECU will automatically memorize the new position. If you don't have specialized tools, this method usually works. Once, after cleaning the throttle, I forgot to match it, and the car jerked when starting. Since then, I've made it a habit. The key point is not to rush driving; first, observe whether the engine temperature stabilizes. The importance of matching lies in preventing unnecessary engine wear, especially for older cars that require more attention to maintenance.
Having dealt with various car issues, I found that the most effective way to match the throttle for the 05 Teana V6 is through tool intervention. For example, using an OBD scanner to reset the ECU adaptation values is simple and quick. Disconnecting the battery at home can also work but is slightly more troublesome. The key is the matching process to restore precise engine control. It's recommended to check the RPM stability after completion.
