Methods to Determine the Condition of an Oil Pressure Sensor

Methods to determine the condition of an oil pressure sensor include observing the oil pressure indicator light, noticeable power loss, and reading fault codes with a diagnostic tool. Observing the oil pressure indicator light: If the oil pressure indicator light remains on after starting the vehicle, the engine should be shut off immediately and the vehicle should be sent for repair as soon as possible. Noticeable power loss: A faulty pressure sensor can lead to inadequate engine lubrication, increasing friction within the cylinders and resulting in reduced power output. Reading fault codes with a diagnostic tool: A specialized diagnostic tool can read the fault code "P01CA," which indicates that the oil pressure sensor voltage is above the upper limit. Causes of oil pressure sensor failure: Insufficient engine oil, dirty or viscous oil, thin oil or excessively high engine temperature, oil pipe leakage, improperly set bypass valve opening pressure, faulty oil pressure switch, pressure gauge or circuit issues, weak pressure relief valve spring, sticking, or damaged ball. Solutions for oil pressure sensor failure: Top up the engine oil, replace with higher-quality oil, inspect and repair the cooling system, oil pipes, and replace the pressure relief valve. There are two types of oil pressure sensors: bimetallic strip type and variable resistance type. When the ignition switch is turned to ON, current flows through the heating coil of the bimetallic strip 4, causing it to deform and separate the contacts. The strip then cools and straightens, closing the contacts again. This cycle repeats, creating a pulsed current in the circuit. When oil pressure is low, the sensor diaphragm 2 deforms less, resulting in lower contact pressure, shorter closing time, longer opening time, and lower frequency changes. This leads to a smaller average current in the circuit, less bending deformation of the bimetallic strip 11, and a smaller pointer deflection angle, indicating low oil pressure. Conversely, when oil pressure is high, the pointer deflection angle increases, indicating high oil pressure. When the base is under force, the resistance strain gauge changes, altering the resistance and thus the voltage across the resistor. However, since this resistance change is minimal, an amplifier is required to amplify the electrical signal. When oil pressure decreases, the resistance of sensor 5 increases, reducing the current in coil L1 and increasing the current in coil L2. The rotor 2 drives the pointer 3 to rotate counterclockwise with the resultant magnetic field, indicating low oil pressure. When oil pressure increases, the resistance of sensor 5 decreases, increasing the current in coil L1 and reducing the current in coil L2. The rotor 2 drives the pointer 3 to rotate clockwise with the resultant magnetic field, indicating high oil pressure.

Does the Dash Cam Continue Recording When the Car is Turned Off?

Normally, a dash cam cannot record when the car is turned off. If the dash cam has a parking monitoring function, it can continue recording after the vehicle is turned off, but the recording time is limited. This is because the dash cam's power is supplied by the car, so it can only operate when the car is running. Some dash cams have built-in batteries, but the battery capacity is too small to support prolonged operation. Connecting the dash cam directly to the car battery can cause prolonged discharge, which may affect the battery's lifespan. A dash cam is a device that records video and audio information during vehicle operation. After installation, it can document the entire driving process, providing crucial evidence in case of traffic accidents. Parking monitoring functions in dash cams come in two types: one is continuous recording, and the other activates short-term recording only when the vehicle detects vibration. However, there are currently no dash cams capable of continuous long-term recording after the car is turned off. For parking monitoring to work, the dash cam must either have an embedded rechargeable battery or be connected to the fuse box (ACC power). After the vehicle is turned off, it automatically enters parking surveillance mode, where sensors continuously monitor the vehicle's status. If any abnormal activity or vibration is detected, the dash cam automatically records and stores the footage separately. Compared to constant power connection, dash cams with parking monitoring connected via the fuse box (ACC) are more energy-efficient and reduce harm to the car battery. However, if the vehicle remains unused for several days, the battery may still drain, making it difficult to start the car.

How to Detect Whether Body Panels Have Been Repainted?

You can use a paint thickness gauge to measure the thickness of the car paint. If the paint thickness exceeds the factory-applied paint value, it indicates that the vehicle has been repainted. You can also judge whether the surface of the panels has been repainted by observing the glossiness and orange peel texture of the paint.

How Can New Drivers Prevent Rear-End Collisions?

Preventing rear-end collisions primarily involves minimizing unnecessary lane changes to avoid disrupting the normal flow of traffic behind you. After completing a lane change or overtaking maneuver, slightly increase your speed when safe to create space for the vehicles behind you. While driving on highways, you may encounter various situations. If an emergency requires sudden braking, always check the following distance of the vehicle behind you in the rearview mirror.

How to Quickly Remove a Paint Protection Film?

Start from the edge and locate the seal. Peel from the edge, avoiding forceful pulling during the process. Instead, use a method of pulling from the inside out. If the film is made of TPU material, it can be removed quickly. There may be slight adhesive residue left at the edges. Spray tar remover on it and wipe it off with a towel.

How to Deal with Scratches Down to the Primer?

When the area of the scratch is not large, you can use a touch-up paint pen for repair. First, wash and dry the car, then shake the paint pen before use to ensure the paint inside is evenly mixed. For deeper scratches, polishing can be used to remove them. If there is a dent after the scratch, it is necessary to go to a repair shop for sheet metal and paint repair.
