What Causes the System Malfunction Warning Light to Illuminate?

Reasons for the system malfunction warning light illuminating: 1. Sensor malfunction: To maintain the optimal air-fuel ratio of the combustible mixture, the ECU monitors the oxygen concentration in the exhaust via the oxygen sensor and adjusts the fuel injection accordingly. If the oxygen sensor fails, the ECU cannot receive the oxygen concentration signal, causing the engine malfunction indicator light to illuminate. 2. Engine knocking: Using gasoline with a lower octane rating than specified, engine overheating, or severe carbon buildup in the combustion chamber can lead to engine knocking. Although the ECU can detect knocking through the knock sensor and mitigate it by delaying ignition timing, if the knocking exceeds the ECU's processing capacity, the engine malfunction indicator light will illuminate due to engine knocking. 3. Mass airflow sensor malfunction: The engine also measures the intake air volume via the mass airflow sensor to control the air-fuel ratio and adjust fuel injection. If the mass airflow sensor malfunctions and the ECU cannot receive the air flow signal, the engine malfunction indicator light will also illuminate.

What happens when you press the accelerator while depressing the clutch?

Pressing the accelerator while depressing the clutch will cause clutch wear, increase engine speed, amplify noise, but the vehicle won't move. Prolonged operation with the engine speed indicator in the red zone may lead to engine seizure. Here's the correct procedure: 1. After starting the engine, depress the clutch pedal, engage the gear, and release the handbrake. 2. Apply slight throttle while gradually releasing the clutch. The key technique is: gradually release the clutch with your left foot while simultaneously increasing throttle with your right foot. When you hear (primarily feel) the engine speed drop, continue releasing the clutch while progressively increasing throttle. 3. After fully releasing the clutch, maintain steady throttle. 4. Once the vehicle gains speed and you sense sufficient engine RPM reserve, you may proceed to shift gears.

What are the simplest and most accurate methods for short individuals to reverse into a parking space?

Here are the simplest and most accurate methods for short individuals to reverse into a parking space: 1. Adjust the seat: Before reversing, it's best for shorter females to raise the seat to its highest position and adjust the backrest angle to nearly vertical. If visibility remains poor even at the highest seat setting or with a vertical backrest, consider using seat cushions or back cushions for assistance. A comfortable seat helps in clearly seeing the front and surroundings of the car; observing the rear wheels and auxiliary lines in the training area; and effortlessly pressing the brake and clutch, even to the point of fully depressing them. 2. Identify reference points: Observe the distance between the car body and the parking space corner in the right rearview mirror, and check the width between the car body and the parking space boundary lines in both left and right rearview mirrors.

Can I switch to automatic transmission after passing Subject 1?

Generally not possible. If you registered for a manual transmission driver's license test, you can negotiate with the driving school to change the registration to an automatic transmission driver's license test and pay the relevant fees before taking the Subject 1 test. After passing the Subject 1 test, a learning driving certificate will be issued. If the Subject 1 test has already been passed, it is usually not possible to switch, but you can try to negotiate with the driving school. Below is relevant information about Subject 1: 1. Test question bank: Since July 2015, the Ministry of Public Security updated the Subject 1 question bank to 1229 questions, with the general question bank remaining unchanged.
