Restore accurate air-fuel mixture monitoring and dependable engine-management operation with this OE Match Lambda Oxygen Sensor. Designed for compatible Porsche applications, this sensor is installed before the catalytic converter, where it measures the oxygen content of the exhaust gases leaving the engine.

- Porsche 957 Cayenne S 4.8L 2007-10
Diagram Ref No 6
Also known as an upstream, pre-cat or O2 sensor, the lambda sensor provides critical feedback to the engine control unit (ECU). By monitoring residual oxygen in the exhaust stream, it allows the ECU to determine whether the engine is running richer or leaner than intended and make continuous adjustments to fuel delivery.
Accurate pre-catalyst lambda sensor information is important for maintaining efficient combustion, responsive performance, fuel economy and emissions control. Unlike a downstream sensor, which is commonly used to monitor catalytic converter performance, the before-catalytic-converter sensor has a direct role in fuel-mixture regulation.
Lambda sensors operate in an extremely demanding environment and are continually exposed to high exhaust temperatures and combustion by-products. Age, contamination, wiring damage or deterioration of the sensing element can eventually cause slow, inaccurate or failed readings.
This OE Match Lambda Oxygen Sensor provides a high-quality replacement for a worn or defective pre-cat sensor, helping restore accurate mixture feedback and correct engine-management operation.
What This Product Does:
- Measures oxygen content in the exhaust gases.
- Is positioned before the catalytic converter.
- Provides air-fuel mixture feedback to the ECU.
- Helps the ECU determine whether combustion is rich or lean.
- Allows continuous adjustment of fuel delivery.
- Supports accurate closed-loop fuel control.
- Helps maintain efficient combustion.
- Contributes to consistent engine performance and throttle response.
- Helps optimise fuel consumption.
- Supports correct operation of the emissions-control system.
- Helps protect the catalytic converter from problems associated with incorrect fuelling.
- Replaces a slow, contaminated, damaged or failed oxygen sensor.
- Provides an OE Match replacement for compatible Porsche applications.
Symptoms Of Wear Or Failure:
- Check engine or engine-management warning light.
- Oxygen sensor or mixture-related diagnostic fault codes.
- Increased fuel consumption.
- Rough or unstable idle.
- Engine hesitation. Poor throttle response.
- Reduced engine performance.
- Engine running excessively rich.
- Engine running excessively lean.
- Increased exhaust emissions.
- Strong fuel smell from the exhaust.
- Failed emissions testing where applicable.
- Intermittent engine-management faults.
- Slow or implausible lambda sensor readings during diagnostic testing.
- Damaged sensor wiring or electrical connector.
- Heater circuit-related sensor faults where applicable.
Why Replacement Matters:
- The pre-catalytic converter lambda sensor is a key feedback device for the engine's fuel-management system. When operating correctly, it allows the ECU to continually fine-tune the air-fuel mixture as driving conditions change.
- As a lambda sensor ages, its response can become slower even before it fails completely. Delayed or inaccurate feedback may cause the ECU to make less precise fuelling corrections, potentially resulting in increased fuel consumption, reduced performance and higher emissions.
- Incorrect fuelling can also affect the catalytic converter. An excessively rich mixture may allow unburned fuel to enter the exhaust, potentially causing the catalyst to operate at abnormally high temperatures. Persistent lean-running conditions can also contribute to poor engine operation and increased combustion temperatures.
- A failed sensor may cause the ECU to rely on substitute values or an alternative control strategy. While the vehicle may continue to operate, performance, efficiency and emissions can be compromised.
- Replacing a defective component with this OE Match Pre-Catalytic Converter Lambda Oxygen Sensor helps restore accurate mixture feedback, efficient combustion and dependable engine-management operation.
