Oxygen Sensor Replacement for Enhanced Engine Efficiency ?
Why This Part Is Essential
The oxygen sensor plays a critical role in your vehicle's fuel management system. It monitors the amount of oxygen in the exhaust gases and sends this information to the engine control unit (ECU). The ECU then adjusts the air-fuel mixture for optimum combustion. Proper fuel balance improves engine performance, reduces emissions, and increases fuel economy.
How It Functions
Positioned in the exhaust system, this sensor detects oxygen levels in the exhaust. When exhaust gases pass over the sensor, it generates a voltage signal based on oxygen content. The ECU interprets this signal to maintain the correct air-fuel mix, ensuring smooth running and compliance with emission standards.
Consequences of Failure
If this sensor malfunctions, your vehicle may experience rough idling, high fuel consumption, engine misfires, and increased emission levels. A faulty sensor can also trigger the check engine light, potentially causing your vehicle to fail emission testing.
