What to Do When the Engine Fault Light Comes On After an Oil Change?
1 Answers
Changing the oil is just a routine maintenance task and is not directly related to the engine fault light coming on. The main reason for the engine fault light illuminating is poor engine combustion conditions. Special cleaning agents can be used to remove carbon deposits, and high-quality fuel additives can be employed to clean the entire fuel system. More details are as follows: 1. The engine fault light (also known as the MIL light) comes on when components monitoring vehicle exhaust emissions fail, and the On-Board Diagnostics (OBD) system detects excessive emissions. Examples include the ignition coil, spark plugs, catalytic converter, exhaust valve, fuel injectors, intake pressure sensor, oxygen sensor, etc. 2. After the engine fault light comes on, there may be some abnormal conditions. If not addressed promptly, it can lead to issues 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 may burn oil. Vehicle exhaust quality may deteriorate, polluting the environment. To maintain the engine in good working condition, car owners can opt for high-quality gasoline, which usually resolves the issue of the engine fault light coming on.
