Bosch 0258017016 - Lambda sensor with vehicle-specific connector

Product Overview

The Bosch 0258017016 is a high‑performance Lambda sensor, also known as an oxygen probe. Designed for vehicle exhaust systems, it provides critical data to the engine control unit (ECU) for precise fuel mixture management and emissions control.

Key Features

• Vehicle‑Specific Connector: The sensor includes a connector that matches the exact wiring harness of the target vehicle, ensuring seamless integration without the need for adapters or additional wiring.
• 5‑Pole Design: With five electrical contacts, it delivers robust signal transmission and reliable communication with the ECU.
• High Accuracy: Engineered to detect oxygen levels in exhaust gases with minimal error, enabling optimal combustion efficiency.
• Durable Construction: Built from corrosion‑resistant materials that withstand high temperatures and harsh exhaust environments for long service life.
• Compact Size: The sensor’s streamlined shape fits easily in tight engine bay spaces, making installation straightforward.

Applications

This Lambda sensor is compatible with a wide range of vehicles from major manufacturers. Common applications include:

• MERCEDES‑BENZ models such as the C‑Class (W203, W204), E‑Class (W211, W212), S‑Class (S221), Sprinter vans, and many others.
• CHRYSLER, DODGE, and JEEP models including the Patriot, Compass, and various truck platforms.
• Other OEMs that use Bosch’s standardized Lambda sensor architecture.

Installation Guide

1. Locate the Existing Sensor: The sensor is typically positioned before or after the catalytic converter, depending on the vehicle design.
2. Disconnect Power and Exhaust: Safely remove any electrical connections and detach the exhaust pipe segment housing the old sensor.
3. Remove Old Sensor: Use a wrench to unscrew the retained nut or clamp holding the probe in place.
4. Install New Bosch 0258017016: Slide the new sensor into the exhaust pipe, aligning it with the mounting flange. Tighten securely.
5. Reconnect Wiring: Plug the vehicle‑specific connector into the ECU harness, ensuring a snug fit.
6. Reattach Exhaust: Reconnect the exhaust segment and secure all fasteners.
7. Test Functionality: Start the engine and verify that the sensor’s signal appears correctly in the diagnostic readout.

Performance Benefits

By delivering accurate oxygen readings, the Bosch Lambda sensor enables:

• Improved fuel economy through precise air‑fuel ratio control.
• Reduced tailpipe emissions, meeting stringent environmental regulations.
• Enhanced engine responsiveness and smooth idle operation.
• Lower risk of catalytic converter damage due to improper combustion.

Maintenance Tips

• Inspect the sensor periodically for signs of wear or corrosion, especially in high‑humidity climates.
• Avoid using harsh chemicals that could degrade the sensor’s internal components.
• If the engine exhibits misfires or rough running, consider checking the Lambda sensor as a potential cause.

Conclusion

The Bosch 0258017016 Lambda sensor with vehicle‑specific connector is engineered for reliability and precision in modern combustion engines. Its thoughtful design—combining a tailored connector, robust five‑pole architecture, and durable construction—ensures that it meets the demanding requirements of both OEMs and aftermarket applications across a broad spectrum of vehicles.
