A failed oxygen sensor prevents the engine from maintaining the optimal fuel mixture, causing carbon monoxide, excess hydrocarbons, black smoke, and possible catalytic converter damage. It also raises fuel consumption, creates unstable idle, reduces power, slows acceleration, and increases exhaust pollution. Prompt diagnosis or replacement resolves these issues. The sensor corrects erratic idle, frequent stalling, and poor acceleration, improving fuel economy and lowering carbon emissions. It also enhances overall engine performance and fuel efficiency.
