Methods to determine if the water temperature sensor is damaged include: 1. The water temperature gauge needle directly points to the highest position; 2. The water temperature gauge needle does not move; 3. Use a digital resistance simulator to simulate water temperature and compare it with the actual situation; 4. Use an infrared thermometer to measure the actual temperature of the water temperature sensor and compare it with the water temperature gauge. The functions of the water temperature sensor are: 1. Through internal resistance changes, it achieves the effect of altering the current passing through the sensor's resistance to drive changes in the water temperature gauge, indirectly reflecting the engine's operating temperature; 2. Provides an analog signal of temperature changes to the engine control unit.

Last time, my car's temperature gauge kept showing the cold zone and didn't move, and the engine light also came on. The air conditioning didn't feel cold enough while driving. I tried restarting the engine several times, and cold starts were particularly difficult, with increased fuel consumption. After checking online, it might be a problem with the coolant temperature sensor. The sensor is responsible for telling the engine computer the coolant temperature data. If it's broken, the computer won't adjust the fuel mixture ratio, which can easily cause engine overheating or starting difficulties. Later, I went to the repair shop, and the mechanic used a diagnostic tool to read the fault code, which showed a P0115 error code, confirming the sensor failure. After replacing the new sensor, everything returned to normal. Ignoring it could lead to serious engine damage over time, making repairs more costly and time-consuming. So, if you notice abnormal temperature gauge readings or difficulty starting the car, you should get it checked as soon as possible and not delay.

What is the normal tire pressure for the Ant?

The normal tire pressure for the Chery Ant ranges between 2.4-2.5 bar. Due to seasonal factors, the tire pressure can be appropriately increased by 0.2 bar in winter and reduced by 0.1 bar in summer. This data complies with the international GBT2978-2008 standard. To check the current tire pressure of the Ant during daily driving, you can activate the tire pressure monitoring system, and the tire pressure values will be displayed on the central LCD screen of the instrument panel. The specific method is to press the CAR button and switch to the tire pressure monitoring system interface. Generally, a tire pressure exceeding 2.8 bar is considered too high, while a tire pressure below 2.0 bar is too low. Hazards of overinflated tires: Reduced friction and adhesion of the tires, affecting braking performance; causes steering wheel vibration and deviation, reducing driving comfort; accelerates wear on the central tread pattern of the tire, shortening its lifespan; increases vehicle vibration, indirectly affecting the lifespan of other components; overstretches the tire cords, reducing elasticity and increasing the load on the vehicle during driving. Hazards of underinflated tires: Increased friction coefficient with the road surface, leading to higher fuel consumption; makes the steering wheel heavy and prone to deviation, compromising driving safety; increases movement in various parts of the tire, causing abnormal heat due to excessive rolling; reduces the functionality of the cords and rubber, leading to delamination or cord breakage and excessive friction with the rim, damaging the tire bead area and causing abnormal wear; multiplies friction between the tire and the ground, sharply raising tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may result in a tire blowout. If the tire pressure monitoring indicator light comes on (a yellow symbol with an irregular circle, no stamp on top, four small spikes at the bottom, and an exclamation mark inside), there are generally three possible reasons: Abnormal tire pressure: Typically, it will alert if the pressure is below 1.8 bar or above 3.0 bar. In this case, a tire inspection and pressure adjustment are required. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure is not reset in time, the system will still record the previous data, causing the tire pressure monitoring light to illuminate. Simply perform a tire pressure reset to resolve this. Damaged tire pressure sensor: The tire pressure sensor, installed inside the tire and connected to the tire inflation valve, monitors the tire pressure. If the sensor is damaged due to impact while driving, the tire pressure warning light will also turn on. For sensor damage, the only solution is to replace it with a new component.

What causes the ABS light to come on in a Volkswagen Bora?

ABS light can illuminate in various states, with different causes and solutions for each state, as detailed below: State 1: ABS warning light stays on (most common). Cause 1: The ABS wheel speed sensor's sensing area is covered by dirt, mud, or other contaminants, affecting its ability to detect the corresponding speed signal. This prevents the ABS control unit from determining the vehicle speed and wheel slip rate, thus failing to issue appropriate commands to regulate braking. Solution: Clean the dirt from the wheel speed sensor and adjust the gap between the sensor and the signal ring to restore normal function. Cause 2: Poor signal transmission due to loose system wiring connections or faulty ABS relay contacts, leading to system malfunction. Solution: Inspect wiring connections and reconnect any loose parts. State 2: ABS warning light intermittently illuminates but turns off during acceleration. Cause: When multiple electrical devices are in use, the battery voltage may drop below 10.5V. As engine speed increases and voltage rises, the ABS light turns off. This can also occur if the ABS system's power supply voltage is too low, such as due to poor terminal contact or grounding issues. Solution: Check the battery's specific gravity; inspect the charging system; examine the power supply (e.g., voltage relay or poor power contact). State 3: ABS warning light remains on after engine start and only turns off when the engine is turned off (IGFF). Cause: Poor grounding connection of the ABS hydraulic valve body; poor electrical connector contact on the ABS hydraulic valve body; ABS control unit failure. Solution: Loosen and then retighten the grounding screw of the hydraulic valve body, cleaning the contact surface if necessary; check if the connector gap has widened; replace the ABS or ABS/ASR control unit. State 4: ABS warning light illuminates during high-speed driving. Cause: At high speeds, the ABS control unit detects a significant discrepancy between rear and front wheel speed signals; incorrect tire or wheel rim specifications. Solution: Refer to the vehicle's specified tire and wheel rim sizes, as indicated on the label near the fuel tank cap. State 5: ABS warning light intermittently illuminates. Cause: Improper adjustment of the brake light switch; poor internal contact in the brake light. Solution: With the engine running, press the brake pedal, push the brake switch linkage down fully with your finger, then release the brake pedal to complete the self-setting position; replace the brake light switch if necessary. If the ABS warning light is on, it is advisable not to continue driving. An illuminated ABS light indicates a malfunction in the vehicle's anti-lock braking system. During emergency braking, if the wheels lock up, the vehicle may skid uncontrollably, preventing the driver from slowing down or adjusting the vehicle's path, posing significant safety risks.

What are the penalties for carrying 11 people in a 7-seater vehicle?

A 7-seater vehicle carrying 11 people constitutes an 80% overload, which will result in a fine and 6 penalty points. Overloaded vehicles bear loads far exceeding the design capacity of roads and bridges, leading to pavement damage and bridge fractures. Increased mass leads to greater inertia, longer braking distances, and higher risks. Vehicles are manufactured based on predetermined technical specifications, including load limits. Overloading alters these original design parameters.

Which lane to turn into when turning left?

After turning left, enter the leftmost lane in the east-west direction. Below is relevant information about traffic regulations: Maintain a safe speed: When driving on the road, motor vehicles must not exceed the maximum speed indicated by speed limit signs. On road sections without speed limit signs, a safe speed should be maintained. Follow traffic signals: When passing through intersections, motor vehicles should proceed according to traffic signals, signs, markings, or the direction of traffic police. When passing through intersections without traffic signals, signs, markings, or traffic police direction, vehicles should slow down and yield to pedestrians and vehicles with the right of way.
