Can You Still Drive When the Engine Fault Light Is On?

[LaBradley]

When the engine fault light comes on, you should stop driving immediately to protect the engine. Continuing to drive may cause damage to the engine. The reasons for the engine fault light illuminating include: 1. Poor gasoline quality leading to incomplete combustion of the air-fuel mixture in the cylinders, resulting in carbon deposits; 2. Excessive mileage causing weakened spark plug performance; 3. Mechanical aging of the vehicle; 4. Damage, poor contact, or signal interruption in components such as the coolant temperature sensor, crankshaft position sensor, air flow sensor, intake air temperature sensor, or oxygen sensor. Solutions for the engine fault light include: 1. Promptly inspecting the condition of the car's engine; 2. Checking the status of the car's sensors, air flow sensor, and spark plug components; 3. Inspecting the vehicle for any knocking issues; 4. Checking for faults in the ignition coils.
