Вот про что и речь то. А вот почему так, вчера опять ездил на машине немного упали обороты но только до 1000. А если немного тронуть педаль то потом опять 1100-1200 и очень долго опускаются до 1000.
Может всетки очень сильно заслонка приоткрыта изначально, ни кто не разбирал ее, может можно както немного прикрыть ее и тем самым снизить поступления воздуха, тогда и ДМРВ правильные параметры отдаст в ЭБУ.
Хотел фото параметров вложить но чет не получается. Подскажите как это сделать.[/img][/code]

скинь АКБ на 5-7 мин. заведи авто и без вкл потребителей пусть поработает минут 20-25 на ХХ(ни чего не вкл и не газуй) на некоторых дорестайлах почему то так обучается БДЗ.

sgusev, Добрый день. У меня такая же проблема. Обороты на холодную 1600, потом по мере прогрева падают до 1000 . Если немного поездить медленно опускаются до до нормы. Вы нашли решение.

Народ, у меня при полностью закрытой заслонке показывает, что она открыта на 16% ... как я понял-это нормально, электрикам мозги не делать, ато итак бегут от меня Smile
Второй прикол - при полностью открытой, опять визуально(!!!) показывает открытие на 86%...... это тоже нормально? Smile (я немного удивлен логике Япов, обычно согласен безоговорочно)

Доброго времени. Как порешали?

Если ваша машина имеет проблемы с оборотами и работой двигателя, рекомендуется проверить наличие кодов ошибок (если таковые имеются) в системе диагностики автомобиля (OBD-II). Это может помочь идентифицировать возможные проблемы. Проведите визуальный осмотр впускной системы, включая заслонку. www.myccpay.com Приоткройте капот и убедитесь, что все элементы на месте, без повреждений и корректно функционируют.

I had the idea that I could locate a few different metal playlists. But I'm going to sample some of it nonetheless.

The Throttle Position Sensor (TPS) in a vehicle like the Lexus LX470 is responsible for monitoring the position of the throttle plate and sending this information to the engine control unit (ECU). The ECU uses this data to determine how much air is entering the engine, which in turn affects fuel delivery and engine performance. If you're looking to set or calibrate the TPS in your LX470, here's a general guide on how to do it:

**Note: Working with sensors and engine components requires some mechanical knowledge. If you're not comfortable with these procedures, it's recommended to consult a professional mechanic.**

1. **Safety First**: Ensure the vehicle is turned off, the ignition is off, and the key is removed.

2. **Locate the TPS**: The TPS is usually located on the throttle body, which is connected to the intake manifold. It will have an electrical connector and be mounted to the throttle body with screws or bolts.

3. **Check Service Manual**: Consult your vehicle's service manual for specific instructions on TPS adjustment or replacement. Different vehicles might have slightly different procedures.

4. **Reset ECU**: Before adjusting the TPS, it's often recommended to reset the ECU. You can do this by disconnecting the negative terminal of the battery for a few minutes and then reconnecting it.

5. **Adjustment Procedure**: If your TPS is adjustable, follow these general steps:

a. **Loosen Bolts**: Loosen the mounting bolts that secure the TPS to the throttle body, but do not remove them completely.

b. **Position the Throttle**: Have someone gently press the gas pedal while you observe the TPS. You want the throttle to be at its closed position (foot off the pedal). Adjust the TPS position if necessary to match this closed position.

c. **Voltage Measurement**: With a multimeter set to the appropriate voltage range, probe the TPS connector pins. You'll want to measure the voltage across the appropriate terminals (reference and signal) while the throttle is in the closed position. The voltage should be within the specifications provided in the service manual.

d. **Adjust if Necessary**: If the voltage reading is not within specifications, you might need to slightly adjust the TPS position. This can be done by gently rotating the TPS in the appropriate direction until the desired voltage range is achieved.

e. **Tighten Bolts**: Once the TPS is correctly positioned, tighten the mounting bolts while keeping the TPS in place.

6. **Recheck**: Recheck the voltage reading after tightening the bolts to ensure that the adjustment didn't change during the tightening process.

7. **Reconnect Battery**: Reconnect the negative terminal of the battery if you disconnected it earlier.

8. **Test Drive**: Start the vehicle and take it for a test drive to ensure that the throttle response and engine performance are normal.

Remember that the exact procedure can vary between different vehicle models and years, so referring to your vehicle's specific service manual is crucial. Additionally, if you're not confident in your ability to perform these adjustments, it's advisable to seek professional help to ensure that the TPS is properly calibrated for optimal engine performance and safety. cfa home

The Throttle Position Sensor (TPS) on a Lexus LX470 is a crucial component that helps regulate the throttle's position and, consequently, the engine's performance. Here are the steps to set or calibrate the TPS:

1. **Gather Necessary Tools**:

- Basic toolkit (screwdrivers, pliers)
- Multimeter (for voltage testing)
- TPS adjustment tool (if needed)

2. **Prepare the Vehicle**:

- Ensure the engine is turned off.
- Locate the TPS. It's usually attached to the throttle body.

3. **Inspect TPS Connections**:

- Check for any loose or damaged wires connected to the TPS. Make sure the connector is secure.

4. **Disconnect the TPS**:

- Unplug the electrical connector from the TPS.

5. **Check TPS Resistance**:

- Set your multimeter to the resistance (ohms) setting.
- Place the multimeter's probes on the terminals of the TPS.
- Gently move the throttle manually and observe the resistance readings. They should change smoothly and without any sudden jumps or drops.

6. **Adjustment Procedure**:

- If the TPS requires adjustment (some models may not be adjustable), follow these steps:

a. Loosen the TPS mounting screws.
b. Slightly rotate the TPS to achieve the correct voltage or resistance reading.
c. Use a TPS adjustment tool or a precision screwdriver to make fine adjustments.
d. Tighten the mounting screws without over-torquing.

7. **Reconnect TPS and Test**:

- Plug the electrical connector back into the TPS.
- Turn on the ignition without starting the engine. This will power up the sensors.
- Use a multimeter to measure the voltage at the TPS terminals. Refer to the vehicle's service manual for the specific voltage range that should be achieved.

8. **Verify Smooth Throttle Response**:

- Start the engine and let it idle for a few moments. Then, gently rev the engine. The throttle response should be smooth and without any hesitation.

9. **Final Adjustments (if needed)**:

- If necessary, fine-tune the TPS adjustment to achieve the desired voltage or resistance reading.

10. **Secure all Connections**:

- Ensure all connectors and screws are properly secured.

11. **Test Drive**:

- Take the vehicle for a test drive to verify that the throttle response is consistent and that there are no abnormal engine behaviors.

Note: It's crucial to refer to the specific service manual for your Lexus LX470 model for precise specifications and adjustment procedures. Additionally, exercise caution while working around the engine and its components to avoid injury or damage to the vehicle. If you're unsure about any step, consider seeking assistance from a qualified mechanic or referring to professional repair guides.disney hub login
