How to Remove the Key from an Automatic Transmission Car?

There are two scenarios where the key of an automatic transmission car cannot be removed: it cannot be pulled out after turning off the engine, or it cannot be turned after insertion. Below are the relevant details: Reasons why the key cannot be removed after turning off the engine: The gear shift lever is not fully returned to the P (Park) position. If the gear shift is not the issue, try turning the steering wheel slightly. It could also be due to obstructions like coins in the gear slot preventing it from returning to position. In this case, the owner should check for any foreign objects blocking the gear slot, remove them, start the car, and shift the gear again to ensure it fully returns to position, after which the key can be removed. Reasons why the key cannot be turned after insertion: This is due to the car's steering wheel auto-lock feature, a security function. It usually activates if the driver accidentally turns the steering wheel left or right after parking and turning off the engine, or if the wheels are not aligned properly when parked. The force applied can cause the steering wheel to turn, triggering the auto-lock mechanism, which engages the steering lock pin with the steering column, making the steering wheel immovable. Even if the key is inserted, it cannot be turned forcefully. If the key cannot be turned after insertion, try gently turning the key with your right hand while simultaneously wiggling the steering wheel left and right with your left hand. The key should then turn.

How many points are deducted for overtime on a hill start?

Half-hill start overtime will deduct 100 points. Half-hill start deduction criteria: 1. After the vehicle stops, if the front bumper of the car or the front axle of the motorcycle is not aligned with the pole line, and the deviation exceeds 50 cm, it is considered a failure; 2. After the vehicle stops, if the front bumper of the car or the front axle of the motorcycle is not aligned with the pole line, but the deviation does not exceed 50 cm, 10 points will be deducted (originally 20 points); 3. After the vehicle stops, if the body is more than 30 cm away from the road edge line but does not exceed 50 cm, 10 points will be deducted (originally 20 points); 4. After the vehicle stops, if the body is more than 50 cm away from the road edge line, 100 points will be deducted; 5. After the vehicle starts, if the vehicle rolls back 10-30 cm, 10 points will be deducted; 6. After the vehicle starts, if the vehicle rolls back more than 30 cm, the test is considered a failure; 7. If the engine stalls once due to improper operation, 10 points will be deducted; 8. After the vehicle stops, if it is not started within 30 seconds, overtime will result in failure; 9. If the parking brake is not tightened after stopping, 10 points will be deducted; 10. If the vehicle rides or presses the solid edge line of the road while moving, it is considered a failure.

What does range mean?

Range refers to the maximum distance a vehicle can travel on the remaining fuel in the tank at a relatively economical speed. The amount of range: Range, also known as driving range, refers to the continuous driving distance a vehicle can achieve on a full tank of fuel under certain road conditions. Generally, vehicles have a range of 300-500 kilometers, while military vehicles typically achieve 600-800 kilometers. Range of new energy vehicles: For new energy vehicles, range refers to the distance the vehicle can travel on a single full charge under ideal road conditions, wind speed, temperature, and other factors. Hybrid vehicles and lead-acid battery vehicles (low-speed vehicles) generally have a shorter range. Factors affecting range: The range of an electric vehicle is influenced by many factors, such as ambient temperature, tire pressure, wind direction, whether the air conditioning is on or off, air resistance on the vehicle body, battery capacity, etc.

What does P0068 Throttle Angle Deviation mean?

Fault code P0068 indicates a throttle angle deviation, which means there is a discrepancy between the angle of the throttle plate controlled by the ECU and the value monitored by the angle sensor. The engine control unit will report an intake manifold throttle angle deviation fault. The causes of throttle angle deviation fault include the following: 1. Intake boost sensor failure: Short circuit or open circuit in the sensor wiring. 2. Throttle solenoid valve failure: Due to prolonged use, aging wiring combined with high current load can easily cause an open circuit in the solenoid valve wiring, preventing the throttle from opening or closing. 3. Lack of timely vehicle maintenance: Accumulated dust and debris in the air filter can obstruct air intake into the engine, leading to abnormal boost pressure.

What is the throttle brake?

The throttle is a speed-regulating brake. Here is some extended information: The function of the throttle: The throttle, also known as the accelerator pedal, is a device on a car's internal combustion engine that controls the fuel supply and is responsible for the acceleration of the vehicle. Components of the throttle brake: The energy supply device includes various components that provide and regulate the energy required for braking and improve the state of the energy transfer medium. The control device includes various components that generate braking actions and control braking effects. The transmission device includes various components that transmit braking energy to the brakes. The brake generates a force (braking force) that resists the movement or tendency of movement of the vehicle, including the retarder in the auxiliary braking system.

What is the Difference Between Aviation Gasoline and Regular Automotive Gasoline?

Aviation gasoline and regular automotive gasoline differ in the following aspects: 1. Purity: Aviation gasoline has higher purity and fewer impurities compared to regular automotive gasoline. 2. Composition: 1) Aviation gasoline is a transparent liquid, blended from high-octane gasoline fractions produced by catalytic cracking or catalytic reforming, along with high-octane components and small amounts of anti-knock agents and antioxidants. 2) Regular automotive gasoline is a liquid fuel refined from petroleum, consisting of straight-run petroleum fractions, secondary processing fractions, and necessary additives. 3. Performance: Aviation gasoline has lower volatility than automotive gasoline, making it less prone to vaporization.
