The methods to determine if the oil pressure sensor is faulty are: 1. After starting the vehicle, if the oil pressure warning light comes on, immediately turn off the engine and send it for repair as soon as possible; 2. Noticeable power loss. A damaged pressure sensor may cause insufficient lubrication in the engine, increasing friction within the cylinders and resulting in reduced power; 3. Using specialized diagnostic equipment to read the fault code "P01CA", which indicates that the oil pressure sensor voltage is above the upper limit. The oil pressure sensor in a car is a crucial device for monitoring the engine's oil pressure, and the data it detects helps ensure the normal operation of the engine.

Does the original owner still own the car after the vehicle files are transferred?

Normally, the registered owner remains the original owner before the transfer procedures are completed. The ownership will only change after the transfer is processed. For vehicles applying for file transfer and ownership transfer, the vehicle owner must fill out an application form, present the vehicle for inspection, and submit relevant proofs and documents. File transfer refers to the process of moving the vehicle's files from the local vehicle management office. The vehicle's files are equivalent to its household registration. During the file transfer, a new registration location and owner (the transferee) will be specified, which is difficult to change once designated. After the file transfer, there are generally two scenarios: The first is external file transfer, where the vehicle is moved from the original licensing office to another vehicle management office, and the ownership remains unchanged, meaning the car still belongs to the original owner. The second is used car file transfer and ownership transfer, where the vehicle is sold to someone else and transferred to their name, making the car belong to the new owner. This scenario involves both file transfer and ownership transfer. If the vehicle is not registered after the file transfer, the original owner may bear certain responsibilities. Failure to register after file transfer can have the following consequences: restricting the owner from handling other transfer registration procedures, the vehicle being considered a 'black car' (unregistered) by the vehicle management office, resulting in 12 penalty points, a warning, and a fine of 20-200 RMB if caught. The original owner may also be involved if an accident occurs. If the original owner's license plate meets the conditions for retaining the 'old' plate, they still cannot continue to use it. Note: To avoid unnecessary trouble, it is recommended to complete the registration and licensing procedures within one month after the file transfer.

How Often Should You Replace Car Key Batteries?

Currently, car key batteries typically last about two years. Generally, remote keys won't suddenly run out of power. When the owner notices that the car doors only unlock when standing very close to the vehicle, it indicates the battery is about to die. Here are some maintenance tips for car keys: Storage Temperature: Do not expose the key to extremely cold environments below 0°C or extremely hot environments above 50°C, as this will significantly reduce battery lifespan. Storage Location: Keep the key in a dry environment, as humid conditions can decrease battery life. Avoid storing the key with hard objects that could scratch the chrome plating on the key.
