Extended Product Information

FAQs

What is the recommended replacement interval for this lambda sensor?

Bosch recommends replacing this lambda sensor at 250,000 km.

What vehicles is this Bosch lambda sensor compatible with?

This sensor is compatible with Porsche 911 (997) 3.6 GT2 Coupe models from September 2007 to August 2009.

Can I install this sensor myself?

No, installation should be performed by trained specialists due to the technical nature of the component and its location on the vehicle.

What does a lambda sensor do?

A lambda sensor measures the amount of oxygen in your vehicle's exhaust gases. This information allows the ECU to adjust the air-fuel mixture for optimal engine combustion and efficiency.

What does '5-circuit' mean for this sensor?

A 5-circuit sensor typically includes elements for both sensing the oxygen content and for heating the sensor to ensure it reaches operating temperature quickly for faster ECU response.

Why is it placed before the catalytic converter?

Placement before the catalytic converter allows the sensor to provide the most accurate real-time data on the air-fuel mixture entering the engine, enabling precise adjustments for optimal combustion.

Troubleshooting

Check Engine Light illuminates with oxygen sensor codes

This indicates a potential issue with the sensor's readings or performance. Verify proper connection and consult a specialist to diagnose if the sensor requires replacement.

Reduced engine performance or fuel economy

A malfunctioning lambda sensor can lead to incorrect air-fuel mixture. Have the sensor and its readings checked by a qualified technician.

Hesitation or stumbling during acceleration

An inaccurate air-fuel mixture, often caused by a faulty lambda sensor, can result in poor acceleration. Professional diagnosis is recommended.
