Is a tire pressure of 1.9 normal? Should it be refilled?

How to Reset the Tire Pressure Warning?

To reset the tire pressure warning in a car, follow these steps: After addressing the tire pressure issue, first turn on the ignition, then press and hold the tire pressure monitoring reset button. Once you hear a "beep," release the button. The tire pressure monitoring system will then store the current normal tire pressure data, automatically clear the previous data, and finally, the warning light on the dashboard will turn off, indicating the tire pressure reset is complete. Tire pressure monitoring automatically checks the tire pressure in real-time while driving and alerts the driver to any leaks or low pressure to ensure driving safety. There are three common types of tire pressure monitoring systems: Direct Tire Pressure Monitoring: This system uses pressure sensors installed in each tire to directly measure tire pressure. The pressure data is transmitted wirelessly from inside the tire to a central receiver module, which then displays the pressure for each tire. If the tire pressure is too low or there is a leak, the system automatically triggers an alert. Indirect Tire Pressure Monitoring: When the pressure in a tire decreases, the vehicle's weight causes that tire's rolling radius to shrink, making it rotate faster than the other wheels. By comparing the rotational speed differences between tires, the system monitors tire pressure. Indirect tire pressure monitoring relies on calculating the rolling radius to assess pressure. Tire Pressure Monitoring System (TPMS) Overview: This system combines the advantages of both direct and indirect monitoring. It equips two diagonally opposite tires with direct sensors and uses a 4-wheel indirect system for the remaining tires. Compared to a full direct system, this hybrid approach reduces costs and overcomes the indirect system's inability to detect simultaneous low pressure in multiple tires. However, it still cannot provide real-time pressure data for all four tires like a full direct system.

Why Can't the Cruze Trunk Open?

Here are the reasons and solutions for the Cruze trunk not opening: 1. Linkage rod or lock cylinder issue. If you have always been using the remote to open the trunk, the lock cylinder might be dirty or rusty. Spraying rust remover into the lock cylinder a few times can help open it. If you frequently use a key to open the trunk, the linkage rod might be broken, and you will need to go to a repair shop to open it. 2. The remote key was not used to unlock the trunk, making it difficult to open. It's best to press the unlock button on the key before opening. 3. The key battery is dead and needs to be replaced with a new one. 4. Mechanical component failure, such as a broken trunk wire or other trunk-related issues causing the trunk not to open. This requires repair at a service center. 5. Five-door cars generally cannot be opened from the inside. Some rugged off-road vehicles, to prevent accidental activation during driving which could lead to injuries, usually do not have an interior trunk switch. Therefore, the trunk can only be opened from the outside.

What to Do When the Car Starter Motor Turns Weakly?

Solutions for weak car starting are as follows: 1. Check the battery capacity and the connection of the power cables. 2. If the battery capacity is sufficient and the wiring connections are good, use a metal strip to short-circuit the two main terminals of the starter solenoid switch. If the starter turns strongly after short-circuiting, it indicates poor contact between the main contacts and the contact disc inside the starter solenoid switch. If the starter still turns weakly after short-circuiting, it can be concluded that the motor has a fault or poor grounding, requiring further disassembly and inspection. 3. After turning on the starter switch, if the starter makes a continuous "clicking" sound and turns normally when the two main terminals of the starter solenoid switch are short-circuited, it indicates a short circuit or open circuit in the holding coil of the solenoid switch.

Why is the engine light on in the Magotan?

Here are the reasons why the engine warning light is on in the Magotan: 1. Poor gasoline quality leads to insufficient combustion of the air-fuel mixture in the cylinders, causing the engine warning light to illuminate. 2. Carbon deposits in the intake passages or on the piston crowns result in poor atomization, leading to incomplete combustion and triggering the warning light. 3. During cold starts, especially when the ambient temperature drops sharply, the warning light may come on due to temperature correction issues in the computer system. However, it will stabilize once the temperature drops to a certain level and remains steady. 4. Faults in the engine control system. This requires using specialized diagnostic equipment to read specific trouble codes to determine the cause, which could be wiring issues, sensor failures, control module malfunctions, etc.

How to Test Whether a Battery is Good or Bad?

Battery monitoring methods for determining quality are: 1. Inspect the exterior: Check whether the battery casing is bulging, leaking, has broken separators, or corroded terminals. If any of these phenomena are present, it indicates the battery is dead; 2. Measure voltage: After charging for two hours, measure the voltage of individual battery cells at 20-minute intervals. If the voltage is below 13V, it indicates a problem. During discharge, measure the voltage three times at 10-minute intervals. If the discharge time is faster than other batteries and the voltage drops below 10V, the battery has an issue; 3. Check for water loss and blackening: After charging the battery for 36 hours, if the charger's red light remains on, it indicates severe water loss. Open the battery's top cover to reveal six circular holes. Check the color of the electrolyte in each hole. If it appears black, it means the lead powder from the plates has shed, indicating the battery is dead.
