Oxygen (O2) Exhaust Sensor
This sensor is vital for keeping the engine running clean and efficient. It measures the oxygen level in the exhaust stream and sends a signal to the ECU so fuel delivery can be corrected in real time. When the air-fuel mix is right, you get smoother power, better fuel economy, and lower emissions ✅
How It Works
Mounted in the exhaust, the sensing tip reacts to oxygen content after combustion. The ECU reads the changing voltage/resistance signal and adjusts injector pulse to keep the mixture near ideal. Many units include an internal heater, helping the sensor reach working temperature quickly after cold starts 🔥
Why You Need It
- Helps prevent rich/lean running
- Protects catalytic converter from fuel overload
- Improves drivability during idle and cruising
What Happens If It Fails
A faulty sensor can cause poor MPG, rough idle, hesitation, fuel smell, higher emissions, and a check engine light ⚠️. Long-term driving with wrong readings may damage the catalytic converter and foul spark plugs.
