Bosch 0258006171 – Lambda Sensor with Vehicle‑Specific Connector

The Bosch 0258006171 is a high‑performance lambda sensor, also known as an oxygen sensor, designed to monitor the oxygen content in exhaust gases before the catalytic converter. This information allows the engine control unit (ECU) to adjust fuel injection and ignition timing for optimal combustion, emissions compliance, and fuel economy.

Key Features & Technical Highlights

• Vehicle‑Specific Connector: The sensor comes with a pre‑wired connector that matches the exact pin configuration of the target vehicle. This eliminates the need for additional wiring harnesses or adapters, ensuring a quick and reliable installation.
• 4‑Wire Design: The sensor uses a standard four‑wire layout: power (12 V), ground, signal output, and heater circuit. The built‑in heater stabilises the sensor temperature rapidly for accurate readings under all operating conditions.
• Pre‑Catalytic Converter Placement: Positioned upstream of the catalytic converter, the sensor provides real‑time data on exhaust gas composition before it passes through the catalyst, enabling precise control of the air‑fuel mixture.
• Durable Construction: Constructed from high‑temperature resistant materials, the sensor can withstand the harsh environment inside an engine bay for extended periods without degradation.
• OEM Quality Assurance: Manufactured by Bosch, a leading automotive component supplier, the sensor meets stringent OEM specifications and is fully compatible with a wide range of Opel, Vauxhall, Chevrolet, Holden, and GMC vehicles.

Compatibility Overview

The Bosch 0258006171 lambda sensor is engineered for numerous models across several brands. Below is an overview of the most common vehicle families and model years that feature this component:

For a definitive fitment check, consult the vehicle’s service manual or an online ECU database that lists part numbers for specific VINs.

Installation & Maintenance Tips

• Removal: Disconnect the battery first. Carefully detach the sensor from the exhaust pipe using a suitable socket set. Avoid damaging the sensor’s wiring harness.
• Installation: Align the pre‑wired connector with the vehicle’s harness. Secure the sensor with the supplied clamp or torque specification to prevent vibration damage.
• Calibration Check: After installation, perform a diagnostic scan to confirm that the ECU reads the sensor correctly and that no fault codes are present.
• Longevity: The sensor’s heater element may fail after prolonged use. If you notice erratic engine performance or increased emissions, replace the sensor promptly.
