Vemo V30-76-0005 Lambda Sensor

Vemo V30-76-0005 Lambda Sensor

The Vemo V30-76-0005 Lambda Sensor is a high‑performance oxygen sensor designed for precise air‑fuel mixture control in modern internal combustion engines. It delivers reliable, real‑time data to the engine management system, enabling optimal combustion efficiency and reduced emissions.

Key Functionalities

• Accurate Oxygen Measurement: The sensor measures the oxygen content in exhaust gases with high precision, allowing the ECU to adjust fuel injection for a stoichiometric mixture.
• Fast Response Time: With a rapid response characteristic, it quickly reacts to changes in engine load and operating conditions, ensuring smooth throttle response.
• Wide Operating Temperature Range: It operates reliably across a broad temperature spectrum, from cold starts to high‑temperature exhaust environments.
• Durable Construction: Built with robust materials and a pre‑greased M18 x 1.5 thread, the sensor withstands harsh automotive conditions.

Design & Compatibility

The V30-76-0005 features an M18 × 1.5 threaded interface with a pre‑greased finish for easy installation and secure mounting. Its compact form factor fits seamlessly into the exhaust manifold or catalytic converter housing of various Mercedes-Benz models, including:

• S-Class (S/W210, C215/W220, W140)
• E-Class
• SL & Sprinter series
• Other compatible vehicles with similar exhaust layouts

The sensor is available in both front and rear positions relative to the catalytic converter, allowing flexibility for different engine bay configurations.

Electrical Interface

• Signal Output: The sensor provides a voltage signal proportional to oxygen concentration, typically ranging from 0.1 V (rich) to 0.9 V (lean).
• Cable Length: Standard cable lengths of up to 515 mm ensure adequate reach without excessive strain.
• Connector Type: The sensor uses a four‑wire connector, compatible with standard lambda sensor harnesses used in Mercedes-Benz vehicles.

Performance Benefits

• Improved Fuel Economy: By maintaining the optimal air‑fuel ratio, the sensor helps reduce fuel consumption and operating costs.
• Lower Emissions: Precise control of combustion reduces harmful exhaust gases such as CO, HC, and NOx, contributing to cleaner emissions.
• Enhanced Engine Longevity: Accurate oxygen sensing protects catalytic converters from damage caused by incorrect fuel mixtures.

Installation & Maintenance Tips

1. Preparation: Ensure the engine is cool and disconnect the battery to avoid electrical hazards.
2. Removal: Use a socket set compatible with M18 threads. Carefully unscrew the old sensor, taking note of any cable routing.
3. Installation: Apply fresh thread sealant if recommended, then screw in the new V30-76-0005 until snug. Reconnect the wiring harness securely.
4. Testing: After installation, reconnect the battery and start the engine. Verify sensor voltage readings with a diagnostic scanner to confirm proper operation.

Quality Assurance

The Vemo V30-76-0005 is manufactured under stringent quality control protocols, ensuring consistent performance across all units. Its design adheres to automotive industry standards for durability and reliability.

Applications Beyond Mercedes-Benz

While the sensor is specifically engineered for certain Mercedes-Benz models, its universal M18 × 1.5 thread and standard electrical interface make it suitable for a range of vehicles that require a high‑quality lambda sensor.

Conclusion

The Vemo V30-76-0005 Lambda Sensor stands out as a dependable, high‑performance component essential for modern engine management. Its precise oxygen measurement, rapid response, and robust construction make it an ideal choice for maintaining optimal combustion efficiency, reducing emissions, and ensuring long‑term engine health.
