What it does

Oxygen sensors measure the oxygen content in exhaust gases, providing essential feedback that can guide adjustments to the air/fuel ratio. When the sensor and system work together as intended, the engine may operate with smoother idle, consistent performance, and optimized control during varied driving conditions.

Real-world use cases
