Rear Air Fuel Ratio Lambda Oxygen Sensor for VO LVO
OE Numbers: 31370195, 30651718
Vehicle Compatibility: VO LVO vehicles
Sensor Type: Upstream lambda sensor
Product Overview
The automotive oxygen sensor is a critical feedback component of the engine management system. Its core function involves real-time monitoring of oxygen content in exhaust gases, enabling the ECU to precisely control the air-fuel ratio for economical, clean, and efficient combustion.
Closed-Loop Control Functions
- Fuel Correction: ECU dynamically adjusts fuel injection quantity based on oxygen sensor signals to maintain optimal air-fuel ratio
- Catalyst Protection: Ensures three-way catalyst operates within optimal efficiency window (conversion rate above 95%)
- Cold Start Management: Provides open-loop control basis during engine warm-up phase
Performance Benefits
- Fuel Efficiency: Prevents prolonged rich combustion, saving 5-15% fuel
- Emission Reduction: Lowers harmful gas emissions including CO, HC, and NOx
- Engine Performance: Prevents spark plug carbon buildup and exhaust pipe corrosion
- Diagnostic Capability: Monitors catalyst aging and detects abnormal engine operation
