Diagram Ref No 32
Also known as a downstream, post-cat or O2 sensor, the lambda sensor measures the oxygen content of the exhaust gases after they have passed through the catalytic converter. This information is transmitted to the engine control unit (ECU), allowing it to assess catalytic converter performance and monitor the emissions-control system.
Unlike the lambda sensor located before the catalytic converter, which plays a primary role in air-fuel mixture control, the downstream sensor is principally responsible for monitoring catalyst efficiency. By comparing upstream and downstream oxygen sensor signals, the ECU can determine whether the catalytic converter is processing exhaust gases effectively.
Continuous exposure to high exhaust temperatures, vibration, moisture and combustion deposits can eventually cause the sensor to respond slowly, produce inaccurate readings or fail electrically.
This OE Match Lambda Oxygen Sensor provides a high-quality replacement for a worn, contaminated or failed downstream sensor, helping restore accurate post-catalyst monitoring.
What This Product Does:
- Is specified for the cylinders 1–3 exhaust bank.
- Is installed AFTER the catalytic converter.
- Measures oxygen content in exhaust gases leaving the catalyst.
- Sends post-catalyst oxygen information to the ECU.
- Helps monitor catalytic converter efficiency.
- Works in conjunction with the upstream lambda sensor.
- Supports onboard emissions diagnostics.
- Helps identify abnormal catalytic converter operation.
- Provides information used to monitor emissions-system performance.
- Helps distinguish sensor faults from genuine catalyst deterioration during diagnosis.
- Replaces a slow, contaminated, damaged or failed downstream sensor.
- Provides an OE Match alternative for compatible Porsche applications.
Symptoms Of Wear Or Failure:
- Check engine or engine-management warning light.
- Downstream oxygen sensor-related diagnostic fault codes.
- Cylinders 1–3 bank sensor faults.
- Post-catalytic converter oxygen sensor fault codes.
- Catalyst-efficiency-related diagnostic codes.
- Intermittent engine-management warnings.
- Implausible or inconsistent oxygen sensor readings.
- Sensor response that is unusually slow during diagnostic testing.
- Sensor output remaining at an abnormal or fixed value.
- Oxygen sensor heater circuit faults.
- Failed emissions testing where applicable.
- Damaged sensor wiring or insulation.
- Corroded or damaged electrical connectors.
- Physical sensor damage caused by heat, corrosion or road debris.
Why Replacement Matters:
- The downstream lambda sensor plays an important role in the vehicle's onboard emissions monitoring system. The ECU relies on its signal to assess how effectively the catalytic converter is processing exhaust gases.
- If the sensor becomes slow or inaccurate, it can provide misleading information about catalyst performance. This may trigger persistent engine-management warning lights or catalyst-efficiency fault codes even when the catalytic converter itself is still functioning correctly.
- A defective heater circuit can also prevent the sensor from reaching its intended operating temperature efficiently, potentially interfering with accurate emissions monitoring.
- Reliable downstream sensor operation is particularly important when diagnosing catalytic converter problems. If the ECU cannot trust the post-catalyst oxygen signal, determining whether the fault lies with the sensor, engine operation or catalytic converter becomes more difficult.
- Correct diagnosis and replacement of a confirmed faulty sensor can also help prevent unnecessary replacement of a significantly more expensive catalytic converter.
- Replacing a defective component with this OE Match Lambda Oxygen Sensor helps restore accurate catalyst monitoring, reliable emissions diagnostics and dependable engine-management operation.

The OE MATCH Lambda Oxygen Sensor is a replacement exhaust-gas sensor designed for installation after the catalytic converter. Also known as an oxygen sensor, O2 sensor or post-cat lambda sensor, it monitors the oxygen content of the exhaust gases downstream of the catalytic converter.
Fits:
- Porsche 958 Cayenne S V8 4.8L Petrol (400Hp) 2010-17

The information produced by the sensor allows the vehicle's engine management and emissions-control systems to monitor catalytic converter efficiency and identify abnormal exhaust or emissions conditions.
What This Product Does:
The lambda sensor measures the oxygen content in the exhaust gases and sends an electrical signal to the vehicle's engine control unit (ECU).
This particular sensor is positioned after the catalytic converter, meaning its primary role differs from an oxygen sensor installed before the catalyst.
The upstream sensor is generally more directly involved in monitoring combustion and fuel mixture, while the post-catalytic-converter sensor monitors the exhaust after it has passed through the catalyst.
This allows the ECU to compare exhaust-gas information and assess whether the catalytic converter is operating effectively.
The post-cat lambda sensor helps:
- Monitor catalytic converter performance
- Measure oxygen levels after the catalyst
- Support emissions-system diagnostics
- Detect abnormal catalyst operation
- Provide feedback to the engine management system
- Identify emissions-related faults
- Help maintain correct onboard diagnostic monitoring
Symptoms Of Wear Or Failure:
Lambda sensors operate in an extremely demanding environment and are continually exposed to high exhaust temperatures, combustion gases and contaminants.
Over time, the sensing element can become contaminated or respond more slowly, while wiring and electrical connections can also deteriorate.
Common symptoms of a failing post-cat oxygen sensor include:
- Check Engine Light / engine-management warning light
- Emissions-related fault codes
- Oxygen sensor fault codes
- Catalyst-efficiency fault codes
- Failed emissions testIncorrect or inconsistent sensor readings
- Slow sensor responseIntermittent engine-management warnings
- Increased emissionsAbnormal diagnostic readings
- Wiring or connector faults
- Physical damage to the sensor or cable
Depending on the vehicle's engine-management strategy, additional drivability or efficiency symptoms may also occur.
Why Replacement Matters:
The vehicle relies on accurate sensor information to monitor its engine and emissions-control systems.
If the post-cat lambda sensor becomes slow, inaccurate or completely inoperative, the ECU may no longer receive reliable information about exhaust conditions downstream of the catalytic converter.
Replacing a confirmed faulty sensor can help restore:
- Accurate exhaust oxygen measurement
- Correct catalytic converter monitoring
- Reliable emissions-system diagnostics
- Proper ECU feedback
- Reduced risk of recurring oxygen-sensor fault codes
- Correct operation of the vehicle's onboard emissions monitoring system
A functioning lambda sensor is particularly important when diagnosing emissions-related warning lights or preparing a vehicle to meet applicable emissions requirements.

Diagram Ref No 7
Also known as an upstream, pre-cat or O2 sensor, the lambda sensor provides essential feedback to the engine control unit (ECU). By measuring residual oxygen in the exhaust stream, it enables the ECU to determine whether the engine is operating with a rich or lean air-fuel mixture and make continuous corrections to fuel delivery.
As a pre-catalytic converter sensor, it has an important role in closed-loop fuel control. Accurate readings help maintain efficient combustion, responsive performance, appropriate fuel consumption and controlled exhaust emissions.
Lambda sensors operate under demanding conditions and are continually exposed to extreme exhaust temperatures, vibration and combustion deposits. With age, the sensing element can become contaminated or slow to respond, while the internal heater, wiring or electrical connections may also deteriorate.
This OE Match Lambda Oxygen Sensor provides a high-quality replacement for a slow, contaminated, damaged or failed original sensor.
What This Product Does:
- Measures oxygen content within the exhaust gases.
- Is designed for installation before the catalytic converter.
- Sends exhaust oxygen information to the ECU.
- Helps determine whether the engine is running rich or lean.
- Allows the ECU to make accurate fuel-delivery adjustments.
- Supports closed-loop air-fuel mixture control.
- Helps maintain efficient combustion.
- Contributes to smooth and responsive engine performance.
- Helps optimise fuel consumption.
- Supports correct exhaust emissions.
- Helps protect the catalytic converter from problems caused by incorrect fuelling.
- Replaces a worn, contaminated or failed oxygen sensor.
- Provides an OE Match alternative for compatible Porsche applications.
Symptoms Of Wear Or Failure:
- Check engine or engine-management warning light.

- Increased fuel consumption.
- Rough or unstable idle.
- Hesitation during acceleration.
- Poor throttle response.
- Reduced engine performance.
- Engine running excessively rich or lean.
- Strong fuel smell from the exhaust.
- Increased exhaust emissions.
- Failed emissions testing where applicable.
- Intermittent engine-management warnings.
- Slow sensor response shown by diagnostic equipment.
- Implausible or inconsistent lambda readings.
- Oxygen sensor heater circuit faults.
- Damaged wiring, insulation or electrical connectors.
Why Replacement Matters:
- The lambda sensor positioned before the catalytic converter is a key feedback component within the engine-management system. The ECU relies on its signal to continually fine-tune the amount of fuel delivered to the engine.
- As a lambda sensor ages, it may become slower to react to changes in exhaust oxygen content. A sensor does not necessarily have to fail completely to affect engine operation; delayed or inaccurate readings can result in less precise fuel corrections.
- Poor mixture control can contribute to increased fuel consumption, reduced performance, unstable running and higher exhaust emissions.
- Incorrect fuelling can also place additional stress on the catalytic converter. If the engine runs excessively rich, unburned fuel can enter the exhaust system and increase catalyst temperatures, potentially shortening catalytic converter service life.
- A failed sensor may cause the ECU to use substitute values or adopt a fallback strategy. Although the engine may continue to run, fuel efficiency, emissions and performance may be compromised.
- Replacing a defective sensor with this OE Match Lambda Oxygen Sensor helps restore accurate mixture feedback, efficient combustion and dependable engine-management operation.

OEMatch Lambda Sensors / Probes — Fit, Function, Confidence
OEMatch Lambda Sensors / Probes components are compatible replacements engineered to original-spec dimensions and tolerances — a practical option when genuine or OEM parts are unavailable. Lambda sensors measure oxygen in exhaust gases and report to the engine control unit so fuel injection and ignition are adjusted for correct combustion in Porsche models, helping to maintain efficient running and emissions control.
Available Types
- Narrowband heated zirconia sensors for stoichiometric control
- Wideband (UEGO) sensors for precise air-fuel ratio feedback
- Pre-catalyst and post-catalyst probes for exhaust monitoring
Understanding OEMatch Lambda Sensors / Probes
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original lambda sensors / probes.
OE (Original Equipment) refers to parts matching original specifications for the lambda sensors / probes and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM lambda sensors / probes engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
Lambda sensors detect oxygen content in exhaust gases and provide a feedback signal used by the ECU to regulate fuel delivery and maintain correct combustion. Sensor designs vary by application; heated elements assist rapid warm-up, while wideband units offer greater resolution for tuning and diagnostics. Correct sensor operation supports catalytic converter efficiency and engine management across a range of Porsche engines.
Benefits Include
- Restores accurate air-fuel control for stable idle and part-throttle response
- Helps reduce emissions and supports catalytic converter protection
- Improves fuel economy by enabling correct mixture control
Why Lambda Sensors / Probes Wear and Fail
- Contamination of the sensing element by oil, coolant or deposits
- Thermal cycling and element degradation from repeated extreme temperatures
- Wiring damage, connector corrosion or poor electrical contact
The Importance of Replacing with OEMatch Lambda Sensors / Probes
Replacing a degraded sensor restores reliable feedback to the ECU, reduces the risk of poor combustion or catalytic converter damage and helps keep emissions within expected limits for Porsche models. OEMatch supplies sensors chosen for compatibility with Porsche mounting and electrical interfaces to simplify replacement while supporting accurate air-fuel control.
Advantages
- Direct-fit options that match factory mounting points and electrical connections
- Available with heated elements or wideband sensing for specific applications
- Corrosion-resistant housings and common connector types for straightforward installation
