- Porsche 955 Cayenne S 4.5L V8 2003-06
Diagram Ref No 6
Also known as an O2 sensor, oxygen sensor or lambda probe, this component measures the oxygen content remaining in the exhaust gases leaving the engine. The sensor sends this information to the engine control unit (ECU), allowing the engine-management system to determine whether combustion is operating richer or leaner than intended.
Because this is a pre-catalyst / upstream sensor, its readings play an important role in fuel-mixture management. The ECU can use the sensor's feedback to adjust fuel delivery, helping maintain efficient combustion, consistent engine performance, controlled emissions and effective catalytic converter operation.
Lambda sensors operate directly in the hot exhaust stream and are exposed to extreme temperatures, vibration, moisture, combustion deposits and repeated thermal cycling. With age, the sensing element can become contaminated or slow to respond, while the internal heater, wiring and electrical connector can also deteriorate.
This OE Match LEFT Lambda Oxygen Sensor provides a high-quality replacement for a confirmed faulty, contaminated or slow-response sensor.
What This Product Does:
- Measures oxygen content in the exhaust gases.
- Fits the LEFT-side exhaust bank where specified.
- Operates BEFORE the catalytic converter.
- Sends exhaust-mixture information to the ECU.
- Helps determine whether the engine is running rich or lean.

Why Replacement Matters:
- The before-catalyst lambda sensor is an important part of the engine's fuel-management system.
- Once the appropriate operating conditions are reached, the ECU can use lambda feedback to continually refine fuel delivery. The sensor must respond accurately as engine speed, load and operating conditions change.
- A worn sensor may continue producing an electrical signal while becoming progressively slower or less accurate.
- Replacing a confirmed faulty OE Match LEFT Lambda Oxygen Sensor helps restore accurate mixture feedback and allows the ECU to manage fuelling correctly.

Diagram Ref No 18
Also known as an oxygen sensor, O2 sensor or lambda probe, the downstream lambda sensor provides important feedback to the engine control unit (ECU). Its primary role is to help the vehicle monitor the performance of the catalytic converter and identify abnormal exhaust or emissions-system behaviour.
The ECU can compare signals from sensors positioned before and after the catalytic converter. This information helps determine whether the catalyst is treating the exhaust gases as expected.
Operating directly in the exhaust system exposes the sensor to high temperatures, vibration, moisture, combustion deposits and repeated thermal cycling. With age, the sensing element can become contaminated or slow to respond, while the internal heater, electrical connector or wiring may also deteriorate.
This OE Match Lambda Oxygen Sensor provides a high-quality replacement for a slow, inaccurate or failed downstream sensor.
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.

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.
