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.

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.

Fits:
Porsche Cayenne 955 Turbo (BEFORE Catalytic converter)
Function:
The Oxygen Sensor (also known as Lambda Sensor) is located in the exhaust manifold and measures the amount of unburned oxygen in your engine's exhaust. Based on the amount of oxygen, it sends a signal to your engine computer which then adjusts the air/fuel mixture for optimum engine performance and emission control.
Failure Symptoms:
• Excessive fuel consumption, a faulty oxygen sensor can waste 30% of your fuel.
• Driveability problems, such as engine surging or hesitation.
• High hydrocarbon emissions, failing an emissions inspection.
• The engine warning light may be on or service flag displayed.
• The ecu/computer stores a mixture-related fault code.
• When the oxygen sensor has stopped functioning completely, the catalytic converter may overheat and fail
Maintenance / Service:
• Test and/or replace every 30,000 miles.
• Perform periodic emission checks.
• Watch for service light.
• Vehicle manufacturers recommend periodic inspection and replacement of oxygen sensor.
