Why can the air pump only reach 4 bars of pressure?

The reason the air pump can only reach 4 bars of pressure is due to the softening of the built-in spring plate in the air pump. Detailed reasons: Over time, the built-in spring plate in the air pump softens. When the air reservoir reaches a certain pressure, the softened spring plate cannot rebound due to the back pressure from the reservoir. This means the maximum pressure achievable with this issue is typically 4-6 kilograms. Replacing the spring plate: Replace the built-in spring plate in the air pump. If the air pump tube is clogged, it's easy to check by disconnecting the tube from the dryer. Start the air pump and observe if black smoke-like substances come out of the tube, indicating a blockage. Repairing air leaks: If there is a leak in one of the four circuits, the four-circuit protection valve will automatically close. This can be easily identified by checking the pressure gauge: if one needle reaches 6 bars while the other shows no pressure at all, there is a leak. The leaking area can then be repaired.

Is it necessary to replace traditional wipers with beam wipers?

Traditional wipers can be replaced with beam wipers, but it depends on the pressure of the wiper bracket of the vehicle model. For example, some Japanese cars have lower wiper bracket pressure, and if beam wipers are used, unclear wiping may occur over time. Different support points: Traditional wipers have multiple support points that are evenly distributed to support the wiper. In contrast, beam wipers only have a single support point in the middle. Beam wipers consist of a single long strip with a smooth curvature. Different noise levels: Beam wipers have a much lower wind resistance coefficient. When used at high speeds, they are much quieter, with almost no audible wiper noise. Traditional wipers, on the other hand, have more frames and occupy more space, resulting in noticeable noise when operating at high speeds. Other aspects: Beam wipers are easier to install and less prone to damage, but they are more expensive. Traditional wipers, however, are more effective at cleaning larger debris.

What are the wheel specifications for the Toyota Mark X?

Toyota Mark X wheel specifications are ET45-8J-5x114.3. Below is a detailed explanation of these specifications: ET45 represents an offset of 45mm: The ET value, also known as the Offset value, refers to the deviation between the mounting surface and the centerline of the wheel rim, measured in millimeters. It can be positive, zero, or negative. When the ET value is 0, the mounting surface is aligned with the wheel's centerline. A larger positive ET value means the mounting surface is more towards the inner side. 8J represents the width and shape of the wheel: The '8' indicates the width of the wheel, and 'J' represents the shape and height of the wheel flange. A wheel of this size can be paired with tires that are 18 inches in diameter and 225/235/245mm in width. 5x114.3 represents the bolt pattern: 5x114.3 indicates that the wheel has 5 bolt holes, with a pitch circle diameter (PCD) of 114.3mm between adjacent holes.

Reasons for Throttle Pedal Signal 1 and 2 Rationality Fault?

Possible causes of the fault: Based on the fault symptoms, the unresponsiveness to throttle input is caused by the fault code P213564, indicating a rationality fault between throttle pedal signal 1 and throttle pedal signal 2. Troubleshooting process: 1. Data reading: The engine data stream was read to analyze the voltage difference between throttle pedal signal 1 and throttle pedal signal 2. It was found that the throttle pedal signal voltage was normal. 2. Accelerator pedal: The signal voltage of accelerator pedal 1 was 0.8V, and the signal voltage of the accelerator pedal was 0.4V, maintaining a proportional relationship, which is normal. However, the ECU reported a fault code that could not be erased. 3. Throttle input: Attempts were made to synchronize the changes of the two signals through pedal throttle input, maintaining the proportional relationship, but the fault code still could not be erased. The inability to erase the fault code means the vehicle cannot be handed over to the customer, necessitating a thorough investigation of this fault point. 4. Disconnecting the pedal connector: The pedal connector was disconnected to measure the pin voltage. The power supply of 5V, signal lines, and ground lines all showed no abnormalities. Replacing the throttle pedal did not resolve the issue.

What does it mean when the ignition switch is in the ON position?

The ignition switch in the ON position means that all basic equipment except the starter is functioning normally. If the key is also in the ON position, all components of the vehicle are powered, including the engine system. The dashboard lights will illuminate, and the fuel pump will begin to build oil pressure. After approximately 5 to 10 seconds, when the fuel pump has fully built oil pressure, the dashboard needles will return to their original positions. Finally, pressing the start switch will start the vehicle. Meanings of other ignition switch positions: LOCK is for locking the car. Generally, when the key is placed in this position, the steering wheel is locked and cannot be moved significantly. ACC provides power to the entire vehicle, allowing the radio, lights, etc., to function normally, but the air conditioning cannot be used. The control process of the car's ignition switch: When the ignition switch is in the "OFF" position, turning the key to the "OFF" (shut) position connects the two internal contact points in the horizontal position, which means the external wires "black-white wire" and "green wire" are connected. If you measure the two wires with an ohmmeter at this time, they should be in a conductive state. In the actual vehicle, the connection of these two wires indicates that the entire circuit system has stopped working, the ignition system circuit is in a short-circuit state, and the engine is turned off.
