NOTE:
Separated plug connection = open reference-air duct.
Damage to oxygen sensor.

- DO NOT use spray, grease, fluid or similar products on the oxygen sensor plug connections.

INFORMATION
- Do not interchange the oxygen sensor in front of the catalytic converter with the sensor behind the catalytic converter as this will result in implausible fault entries.
- The plugs themselves are coded and cannot be interchanged.

Diagnostic conditions
- then Driving > 10 Minute(s) , at:
- Engine at operating temperature
- Exhaust gas temperature > 200 °C (°F)
- min 1 Overrun phase(s) > 6 Second(s)

- then > 40 Second(s) Idle speed
