The oxygen (O2) sensor is a vital automotive component that monitors oxygen levels in exhaust gases to ensure the engine’s air-fuel mixture is optimal for efficient combustion and reduced emissions. Positioned in the exhaust manifold or pipe, it generates a voltage signal—low (~0.1V) for lean mixtures with excess oxygen, and high (~0.9V) for rich mixtures—feeding data to the ECU for real-time adjustments that boost fuel economy and cut pollutants like HC, CO, and NOx.

🔧 What does the O2 sensor do? The oxygen sensor monitors the amount of oxygen in the exhaust gases. It sends this information to the engine control unit (ECU), which uses it to adjust the air-fuel mixture going into the engine. ⸻ ⚠️ When the O2 sensor is bad: • It sends wrong data or no data to the ECU. • The ECU can’t correctly balance the air-to-fuel ratio. • The car ends up running either: • Too rich (more fuel than needed) → wastes fuel • Too lean (less fuel) → poor performance and damage r
