The Malfunction Indicator Lamp (MIL), commonly known as the "Check Engine Light", usually indicates the need for service related to the engine or emissions system. If the check engine light is illuminated, it is best to have your vehicle inspected by a qualified mechanic as soon as possible to identify the underlying issue.
Common Causes:
- Exhaust gas recirculation (EGR) system issues
- Faulty oxygen sensors
- Catalytic converter problems
- Ignition coil or spark plug failure
- Fuel injector issues
- Transmission problems (in some cases)
- Evaporative emissions system faults
Additional Symptoms:
In addition to the illuminated check engine light, you may also notice other symptoms such as:
- Rough idling
- Reduced engine power
- Engine misfires
- Increased fuel consumption
- Unusual noises or vibrations
- Decreased performance
- Transmission issues (gear shifting problems)
Importance:
It's crucial to address the check engine light promptly to avoid potential damage to your vehicle's engine and emission control systems. Ignoring the light may lead to costly repairs and further complications down the road.
