06 Teana 230JK Throttle Oil Return Pause Throttle Abnormal Sound. Come in and talk about it.

Symptom description: There is a high possibility of abnormal noise in the engine compartment. Most people also judge the abnormal noise in the engine compartment according to the sound source, usually the harsh noise of metal or the noise of the wind whistling.

Solution: The abnormal sound of the engine indicates that the technical state of a certain mechanism of the engine has changed. The main reason is that some parts are worn or even improperly adjusted. Some abnormal sounds can indicate that the engine may be accidentally damaged, so when the engine has abnormal sounds, it should be repaired in time to prevent the fault from expanding.

2. The gearbox has abnormal sound.

Symptoms: If there is a "rustling" sound inside the gearbox when the car is driving, but it disappears after stepping on the clutch or accelerator, there will be a whistle when shifting gears.

Solution: There are many transmission parts, and the causes of noise are complicated. When analyzing and judging, we should pay attention to whether it is related to a specific speed. For example, the noise of some planetary gears is obvious around 50 km/h, and whether it is related to some gears is very important for judging the fault of the transmission. If a gear rings, it must be related to the parts that affect the transmission of that gear. If all gears ring, it is often the fault of the normally meshed gear shaft or the lack of oil in the transmission. Whether it is related to specific actions, such as upshifting, downshifting, starting, sudden acceleration, sudden deceleration, turning, etc. It is an effective means to judge abnormal sound, and changing the speed and direction is particularly important to judge the rear axle fault.

If the abnormal sound of the transmission is obvious, it is recommended to send it to a professional repair shop to check the faulty parts and then replace them.

3. The door has abnormal sound.

Symptoms: When you step on the accelerator or brake while driving, there is always some abnormal noise in a certain part of the car body, which is not loud and does not affect the normal driving, but it always makes people a little worried about what the problem is.

Solution:

The abnormal sound of the door is mainly caused by insufficient lubrication, but it is necessary to judge whether it is the hinge position of the door or the glass lifter, door lock mechanism and handle mechanism inside the door. If it is a door hinge or stopper, the special grease for door hinge and slideway can be used, while the special grease for door accessories can be used for lubricating the glass lifter, door lock mechanism and handle mechanism in the door.
