What Are the Common Faults of the Intake Pressure Sensor?

Common faults of the automobile intake pressure sensor include: 1. Short circuit or open circuit inside the sensor; 2. The output signal of the sensor does not change with the variation of intake manifold vacuum; 3. The output signal voltage is too high or too low, deviating from the normal range. Below is relevant information: 1. The intake pressure sensor is used to detect the engine's intake air volume and control the basic fuel injection quantity. It detects the absolute pressure in the intake manifold behind the throttle valve, based on engine speed and load, and converts the changes in manifold absolute pressure into a signal voltage sent to the Engine Control Unit (ECU). The ECU controls the basic fuel injection quantity according to the magnitude of this signal voltage. 2. If this sensor is damaged, the ECU cannot receive the intake air volume, leading to an overly rich or lean air-fuel mixture. An overly rich mixture can cause black smoke, incomplete combustion, or even backfiring from the exhaust pipe. A lean mixture can result in insufficient fuel supply.

What Causes Uneven Wear on the Outer Side of Both Front Wheels Without Causing Pulling?

The reasons for uneven wear on the outer side of both front wheels may include incorrect toe-in values, incorrect camber angles, or chassis deformation in non-adjustable suspension systems. Below are the relevant explanations: 1. Incorrect toe-in or camber angles can be resolved by performing a wheel alignment. For chassis deformation, it is best to have it inspected and repaired by professionals. If only the outer sides of both front wheels are wearing unevenly without causing pulling, it is likely due to excessive camber angle or chassis deformation. 2. Front wheel toe-in refers to the difference in distance between the front and rear edges of the front wheels in the lateral direction of the car. Its main purpose is to compensate for the adverse effects of wheel side slip caused by steering and the influence of tangential road reaction forces on the front wheels. If the toe-in value is too large, it can cause severe wear on the outer side of the tire tread, presenting a sawtooth-like wear pattern from the outer to the inner side of the tread, and may also cause the vehicle to pull during driving.

How long will the car battery last if the interior light is left on?

The power consumption of car interior lights is relatively low. If you forget to turn them off, it would take approximately 20 hours to affect the battery and drain it. Here's some relevant information: 1. For most car models on the market, if the turn signal is left on, it will activate the parking light function. If the left turn signal is left on, the small light on the left side of the car will stay lit; if the right one is left on, the right side will stay lit. These small lights have much lower power than headlights, and even if forgotten, only one side remains lit, not both, so the battery can typically last one night without issues. 2. If the hazard lights (double flashers) are accidentally left on all night, the turn signals may indeed stay illuminated. The power of turn signals varies by model, ranging from 10 watts to 21 watts. Taking 21-watt turn signals as an example, with four lights (front and rear) totaling 84 watts, plus additional lights on side mirrors or body panels on some models, the total power consumption can be comparable to two xenon headlights. In such cases, the battery might last around 9 hours.

What to Do When a Car Battery Fails?

Battery failures and their solutions are as follows: 1. Sulfation of plates: For mildly sulfated batteries, a long-term low-current charging method can be used to eliminate the sulfation; for more severe sulfation, a desulfation charging method should be employed; batteries with extremely severe sulfation should be scrapped. 2. Active material shedding: For lead-acid batteries with shed active material, if the sediment is minimal, it can be cleaned and the battery can continue to be used; if the sediment is excessive, new plates and electrolyte should be replaced. 3. Plate grid corrosion: For batteries with minor corrosion, if there are impurities in the electrolyte, the electrolyte should be poured out, and the battery should be repeatedly rinsed with distilled water before adding new electrolyte and charging for reuse; for batteries with more severe corrosion, if the electrolyte density is too high, it should be adjusted to the specified value and the battery can continue to be used without charging; for batteries with severe corrosion, such as broken grids or large chunks of active material shedding, the plates should be replaced.

Where is the license plate number starting with Su R from?

Su is the abbreviation for Jiangsu Province. There is no license plate number starting with Su R in Jiangsu Province. Relevant information is as follows: 1. The first character of the license plate represents the provincial-level administrative region where the vehicle is registered, which is the abbreviation of each (province, municipality directly under the central government, autonomous region). The second English letter of the license plate represents the prefecture-level administrative region where the vehicle is registered, which is the letter code for each (prefecture-level city, region, autonomous prefecture, league). It is usually ranked by the provincial vehicle management office based on the status of each prefecture-level administrative region. 2. The license plate codes for various regions in Jiangsu Province are as follows: Su A Nanjing, Su B Wuxi, Su C Xuzhou, Su D Changzhou, Su E Suzhou, Su F Nantong, Su G Lianyungang, Su H Huaian, Su J Yancheng, Su K Yangzhou, Su L Zhenjiang, Su M Taizhou, Su N Suqian, Su U Suzhou as an addition.
