Reasons for Honda Engine Emission Failure?

[DeJulia]

Honda engine emission control system failures can be caused by: substandard gasoline quality leading to catalytic converter poisoning, or damage to the oxygen sensors in the catalytic converter system. The impacts of engine emission control system failure include: 1. Affecting other systems: The mixture correction loses its basis, causing inaccurate fuel injection control by the computer. Over time, this can affect the engine, catalytic converter, oxygen sensors, etc., with noticeable abnormalities in engine power, fuel consumption, and idle speed. 2. Performance degradation: Due to fuel or lubricant issues, the catalytic converter may become poisoned and its activity reduced, affecting catalytic conversion efficiency. Sulfur and phosphorus complexes and deposits may form inside the catalytic converter, leading to vehicle performance degradation, reduced power performance, increased fuel consumption, and worsened emissions.
