In daily driving, 19 hacker owners may encounter the engine fault light lighting up, which is usually a warning issued after the vehicle electronic system detects some abnormalities. Understanding these possible causes is crucial to diagnosing and repairing problems in a timely manner.

2. Fuel system failure: Problems with components such as fuel pumps, fuel filters or fuel injectors can affect fuel supply and injection, causing abnormal engine operation.

3. Oxygen sensor failure: The oxygen sensor is responsible for monitoring the oxygen content in the exhaust gas to adjust the fuel injection amount. If the sensor is damaged or contaminated, it may cause the engine control unit (ECU) to receive erroneous data and illuminate the fault light.

4. Emission control system problems: Including catalytic converter, EGR valve and evaporative emission control system, failure of these components will affect the emission performance of the vehicle and trigger fault lights.

5. Engine mechanical problems: Wear or damage to mechanical parts such as valves, piston rings or crankshafts may also lead to reduced engine performance and cause trouble lights to light up.

6. Electronic control unit (ECU) problem: The ECU is the core of controlling engine operation. If the ECU itself fails, it may cause the system to mistakenly trigger the fault light.

To more intuitively show these possible causes, the following is a simplified table listing the possibilities of various failures and corresponding solutions:

Reason of failure Possibility solution Ignition system problem Medium Check and replace damaged components Fuel system failure High Cleaning or replacing related components Oxygen sensor failure Medium replace Oxygen sensor Emission control system problem Low Check and repair emission system Engine mechanical problem Low Carry out mechanical repair ECU problem Low Check ECU and perform necessary programming or replacement

When the engine fault light of the 19 hackers lights up, it is recommended that car owners first use the OBD-II diagnostic tool to read the fault code, which will help quickly locate the problem. Subsequently, based on the instructions of the fault code, relevant components can be inspected and repaired in a targeted manner. When dealing with such issues, timeliness and accuracy are key to avoid possible further damage or safety risks.
