What are the common issues when the car warning light comes on?
1 Answers
The reasons for the vehicle warning light coming on include faults in the coolant temperature sensor, crankshaft sensor, oxygen sensor, spark plugs, ignition coils, etc. Here is some relevant information about the engine warning light: 1. Reasons for the light coming on: The engine warning light (referred to as the MIL light) illuminates when components monitoring vehicle exhaust emissions malfunction, and the On-Board Diagnostics (OBD) system detects excessive emissions. Examples include issues with the ignition coil, spark plugs, catalytic converter, exhaust valve, fuel injector, intake pressure sensor, oxygen sensor, etc. 2. Consequences of the light coming on: When the engine warning light is on, the engine may operate abnormally. If not addressed promptly, it can lead to problems such as increased combustion chamber temperature and accelerated wear, potentially causing premature engine damage. Engine noise may increase, affecting driving and passenger comfort. Fuel consumption may rise, wasting petroleum and financial resources. The engine might burn oil, and exhaust emissions may deteriorate, polluting the environment. To maintain the engine in good working condition, owners can opt for higher-quality gasoline, which often resolves the issue of the engine warning light illuminating.
