How to Deal with Engine Emission Failure?

[LeBrynlee]

Engine emission system failure should be promptly inspected and repaired at a maintenance facility. The causes of engine emission system failure are as follows: 1. Check the spark plugs and cylinder wires. 2. Perform a fuel pressure system inspection. 3. Inspect the injectors of each cylinder. 4. Check the fuel pump and fuel pump circuit. 5. Additionally, inspect the cylinder pressure, intake and exhaust valve clearance, fuel vapor control solenoid valve, EGR valve cylinder operation, and whether the intake manifold is leaking. Below are the reasons why the engine exhaust system warning light may illuminate: 1. Poor quality gasoline, which may lead to abnormal mixture ratios, electronic device failures, and exhaust system abnormalities. 2. Faulty electronic components in the intake system, such as oxygen sensors, carbon canister solenoid valves, throttle bodies, and engine carbon buildup. 3. The engine control program may require updates or debugging. 4. Once the engine warning light comes on, it indicates changes in engine parameters. If not addressed promptly, the engine combustion state will remain unadjusted to normal conditions.
