Peugeot 206 Oxygen Sensor Guide: BOSCH vs VALEO vs SAGEM

Which Oxygen Sensor Does Your Peugeot 206 Need?

The Peugeot 206 was produced with several different engine management systems depending on the model year and trim. This means the correct oxygen sensor varies significantly between variants. Using the wrong sensor can cause ECU errors, poor performance, and failed emissions tests.

The Three Main ECU Systems

1. BOSCH (206-T5)

Peugeot 206-T5 models equipped with the BOSCH engine management system require the 0258006185 lambda sensor. This is a 4-wire heated sensor designed for precise closed-loop fuel control.

• OEM Reference: 0258006185
• Wire configuration: 4-wire
• Compatible: Peugeot 206-T5 BOSCH

2. SAGEM (206-T2)

The 206-T2 with SAGEM ECU also uses the 0258006185 sensor, making it compatible across both BOSCH and SAGEM variants of the T2/T5 platform.

• OEM Reference: 0258006185
• Compatible: Peugeot 206-T2 SAGEM

3. VALEO (206-T2 J34)

The VALEO-equipped 206-T2 (J34) requires a different sensor — the OZA608-U2. This is a common source of confusion and incorrect fitment.

• OEM Reference: OZA608-U2
• Compatible: Peugeot 206-T2 VALEO (J34)

Universal Peugeot 206 Option

For general Peugeot 206 applications, the OZA495-PG2 offers broad compatibility across multiple variants.
