• Rapid Response Time: Delivers quick voltage changes, enabling the engine control unit to adjust fuel injection and ignition timing for optimal combustion.
• Wide Operating Temperature Range: Maintains performance from -40 °C to +120 °C, suitable for both pre‑catalyst and post‑catalyst locations.
• Durable Construction: Encased in a robust housing that resists corrosion and mechanical shock during operation.

Vehicle Compatibility

The sensor is engineered to fit the following vehicle families, demonstrating its versatility across multiple platforms:

• CITROËN: C‑Elysée, C3, C4, Xantia, Synergie, Berlingo, and others.
• PEUGEOT: 206, 307, 406, 607, 808, 308, and various model years.
• FIAT & LANCIA: Ulysses (220), 1.6L engines, and other common models.

Installation Highlights

The Bosch 0258006029 comes with a vehicle‑specific connector, eliminating the need for additional adapters or modifications. Installation steps typically involve:

1. Disconnecting the battery: For safety during sensor replacement.
2. Removing the old sensor: Using a socket set to unscrew the mounting bolt.
3. Connecting the new sensor: Aligning the connector with the vehicle’s harness and securing it firmly.
4. Re‑checking alignment: Ensuring no loose connections or misalignments that could affect sensor performance.
