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.

Diagram Ref No 18
Also referred to as an oxygen sensor, O2 sensor or lambda probe, the downstream sensor provides the engine control unit (ECU) with information about exhaust conditions following catalytic treatment. This allows the vehicle's onboard diagnostic system to monitor catalytic converter performance and identify abnormalities within the emissions system.
The ECU can compare signals from oxygen sensors located before and after the catalytic converter. Differences between these readings help determine whether the catalyst is processing exhaust gases as expected.
Operating directly within the exhaust system exposes the sensor to extreme temperatures, vibration, moisture and combustion deposits. Repeated heating and cooling cycles can eventually cause the sensing element, heater circuit, wiring or electrical connections to deteriorate.
Replacing a confirmed faulty sensor with the correct Porsche Lambda Oxygen Sensor 9A7906265E helps restore dependable catalyst monitoring and accurate emissions-system diagnostics.
What This Product Does:
- Measures oxygen content in the exhaust gases.
- Operates AFTER the catalytic converter.
- Monitors exhaust conditions downstream of the catalyst.
- Sends oxygen-sensor information to the ECU.
- Helps monitor catalytic converter performance.
- Allows comparison with upstream lambda sensor readings.
- Supports onboard emissions diagnostics.
- Helps identify abnormal catalyst behaviour.
- Provides information used to detect emissions-system faults.
- Supports reliable exhaust-system monitoring.
- Helps the vehicle identify sensor and catalyst-related problems.
- Replaces a slow, contaminated or failed downstream sensor.
- Provides a Porsche replacement component for compatible applications.
Symptoms Of Wear Or Failure:
- Check engine or engine-management warning light.
- Lambda sensor-related diagnostic fault codes.
- Downstream oxygen sensor fault codes.
- Catalyst-efficiency fault codes.
- Emissions-system warning messages.
- Slow sensor response during diagnostics.
- Implausible downstream oxygen readings.
- Sensor output remaining unusually fixed.
- Intermittent sensor signals.
- Vehicle failing an emissions test.
- Increased exhaust emissions.
- Oxygen sensor heater circuit faults.
- Open- or short-circuit fault codes.
- Damaged sensor wiring.
- Heat-damaged wiring insulation.
- Corroded electrical terminals.
- Damaged electrical connector.
- Physical damage to the sensor.
Why Replacement Matters:
- The downstream oxygen sensor plays an important role in monitoring the vehicle's emissions-control system.
- If the sensor becomes slow, inaccurate or completely inoperative, the ECU may no longer receive dependable information about exhaust conditions after the catalytic converter.
- Replacing a confirmed faulty Porsche Lambda Oxygen Sensor 9A7906265E restores reliable downstream exhaust feedback and helps the vehicle accurately assess catalytic converter operation.

Diagram Ref No 18
Also known as an oxygen sensor, O2 sensor or lambda probe, the downstream sensor supplies exhaust-gas information to the engine control unit (ECU). Its primary role is to help the vehicle assess catalytic converter operation and monitor the performance of the emissions-control system.
By comparing signals from lambda sensors positioned before and after the catalytic converter, the ECU can identify whether exhaust-gas treatment is occurring as expected and detect certain catalyst or sensor-related faults.
Lambda sensors operate in a particularly harsh environment, exposed to high exhaust temperatures, vibration, moisture, combustion deposits and repeated thermal cycling. Over time, the sensing element may become contaminated or slow to respond, while the internal heater, wiring or electrical connector can also deteriorate.
This OE Match Lambda Oxygen Sensor provides a high-quality replacement for a confirmed faulty, contaminated or slow-response downstream sensor.
