Diagram Ref No 13
Also known as a lambda sensor or oxygen/O2 sensor, the probe operates in an exceptionally demanding environment close to the turbocharger and exhaust system. It is exposed to extremely high temperatures, rapid thermal cycling, vibration and combustion deposits.
Accurate lambda information is particularly important on a turbocharged engine, where correct fuelling and exhaust conditions contribute to engine performance, emissions control and protection of high-temperature components such as the turbocharger and catalytic converter.
As the sensor ages, its response can become slower or inaccurate. Internal heater failure, contamination, damaged wiring or connector problems can also cause sensor faults. Replacing a confirmed defective unit with the correct Porsche Lambda Probe PAC906262A helps restore accurate exhaust monitoring and reliable engine-management feedback.
What This Product Does:
- Measures oxygen content within the exhaust gases.
- Sends exhaust-condition information to the ECU.
- Helps the engine-management system monitor combustion.
- Supports accurate air-fuel mixture management where applicable.
- Helps identify rich or lean operating conditions.
- Supports efficient turbocharged engine operation.
- Helps maintain controlled exhaust emissions.
- Provides information for onboard diagnostics.
- Supports correct emissions-system operation.
- Helps protect exhaust and catalyst components from incorrect running conditions.
- Operates within the high-temperature turbocharger/exhaust environment.
- Replaces a slow, contaminated, inaccurate or failed lambda probe.
- Provides a Porsche replacement component for compatible applications.
- Check engine or engine-management warning light.
- Lambda or oxygen-sensor diagnostic fault codes.
- Rich or lean mixture fault codes.
- Increased fuel consumption.
- Rough or unstable idle.
- Engine hesitation.
- Poor throttle response.
- Reduced engine performance.
- Inconsistent power delivery.
- Engine misfires.
- Increased exhaust emissions.
- Failed emissions test.
- Strong fuel smell from the exhaust.
- Slow lambda response during diagnostic testing.
- Implausible oxygen-sensor readings.
- Intermittent sensor signals.
- Lambda sensor heater circuit faults.
- Damaged or heat-affected wiring.
- Corroded or damaged electrical connectors.
Why Replacement Matters:
- The lambda probe provides the ECU with important information about conditions within the exhaust system.
- A sensor does not always fail suddenly. As it deteriorates, it may continue generating a signal but become increasingly slow or inaccurate.
- Replacing a confirmed faulty Porsche Lambda Probe PAC906262A helps restore accurate exhaust feedback and allows the engine-management system to operate as intended.

Diagram Ref No 18
Also known as an oxygen sensor, O2 sensor or lambda probe, the downstream sensor provides the engine control unit (ECU) with information that helps assess catalytic converter operation and overall emissions-system performance.
The ECU can compare readings from oxygen sensors positioned before and after the catalytic converter. A correctly functioning catalyst changes the characteristics of the exhaust gases passing through it, and the downstream sensor allows the vehicle to monitor whether this process is occurring as expected.
Lambda sensors operate in an extremely demanding environment, exposed to high exhaust temperatures, vibration, moisture, combustion deposits and repeated thermal cycling. Over time, the sensing element, internal heater, wiring or electrical connections can deteriorate.
Replacing a confirmed faulty sensor with the correct Porsche Lambda Oxygen Sensor 9A790626550 helps restore reliable downstream exhaust monitoring and accurate catalytic converter diagnostics.
What This Product Does:
- Measures oxygen content in the exhaust gases.
- Operates AFTER the catalytic converter.
- Sends exhaust oxygen information to the ECU.
- Helps monitor catalytic converter performance.
- Allows comparison with upstream lambda sensor readings.
- Supports emissions-system diagnostics.
- Helps detect abnormal catalytic converter behaviour.
- Provides feedback on downstream exhaust conditions.
- Supports reliable engine-management monitoring.
- Helps identify emissions-system faults.
- Works with the vehicle's wider exhaust and emissions-control system.
- Replaces a slow, contaminated or failed downstream oxygen sensor.
- Restores reliable catalyst-monitoring information when sensor failure is confirmed.
Symptoms Of Wear Or Failure:
- Check engine or engine-management warning light.
- Oxygen sensor-related diagnostic fault codes.
- Downstream lambda sensor fault codes.
- Catalyst-efficiency-related fault codes.
- Emissions-system warning messages.
- Slow oxygen sensor response.
- Implausible downstream sensor readings.
- Intermittent sensor signals.
- Sensor reading remaining unusually fixed.
- Vehicle failing an emissions test.
- Increased exhaust emissions.
- Sensor heater circuit fault.
- Open- or short-circuit sensor faults.
- Damaged sensor wiring.
- Heat-damaged wiring insulation.
- Corroded or damaged electrical connector.
- Physical damage to the sensor.
- Sensor seized into its exhaust mounting point.
Why Replacement Matters:
- The downstream oxygen sensor is an important part of the vehicle's emissions-monitoring system.
- While a before-catalyst sensor is generally more directly involved in air-fuel mixture control, the after-catalyst sensor primarily allows the ECU to monitor the behaviour and efficiency of the catalytic converter.
- If the downstream sensor becomes slow, inaccurate or completely inoperative, the ECU may no longer receive trustworthy information about exhaust conditions after the catalyst.
- Replacing a confirmed faulty Porsche Lambda Oxygen Sensor 9A790626550 restores dependable downstream exhaust information and allows the ECU to monitor catalytic converter operation correctly.
