- Porsche 958 Cayenne V6 3.6L Petrol (300Hp) 2010-17
Restore accurate fuel-mixture monitoring and dependable engine-management performance with this OE Match Right Lambda Oxygen Sensor. Designed for compatible Porsche applications, this sensor is specified for the RIGHT side, BEFORE the catalytic converter.
Fits:- Porsche 958 Cayenne V6 3.6L Petrol (300Hp) 2010-17
Diagram Ref No 18
Also known as an upstream, pre-cat or O2 sensor, the lambda sensor measures the oxygen content remaining in the exhaust gases after combustion. This information is sent to the engine control unit (ECU), allowing it to determine whether the engine is operating with a rich or lean air-fuel mixture and make precise adjustments to fuel delivery.
Because this sensor operates before the catalytic converter, it plays an important role in closed-loop fuel control. Accurate readings help maintain efficient combustion, responsive engine performance, appropriate fuel consumption and controlled exhaust emissions.
Lambda sensors operate in a particularly demanding environment, exposed to extreme exhaust temperatures, vibration and combustion deposits. Over time, the sensing element can become contaminated or slow to respond, while the heater circuit, wiring or electrical connector can also deteriorate.
This OE Match Right Lambda Oxygen Sensor provides a high-quality replacement for a worn, contaminated, damaged or failed original sensor.
What This Product Does:
- Is designed for the RIGHT-side application.
- Is positioned BEFORE the catalytic converter.
- Measures oxygen content in the exhaust gases.
- Sends exhaust oxygen information to the ECU.
- Helps determine whether the air-fuel mixture is rich or lean.
- Allows the ECU to make continuous fuel-delivery corrections.
- Supports accurate closed-loop mixture control.
- Helps maintain efficient combustion.
- Supports smooth throttle response and engine performance.
- Helps optimise fuel consumption.
- Contributes to correct exhaust emissions.
- Helps protect the catalytic converter from problems associated with incorrect fuelling.
- Replaces a slow, contaminated, damaged or failed lambda sensor.
- Provides an OE Match alternative for compatible Porsche applications.
Symptoms Of Wear Or Failure:
- Check engine or engine-management warning light.
- Lambda or oxygen sensor-related diagnostic fault codes.
- Bank-specific rich or lean mixture fault codes.
- 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 during diagnostic testing.
- Implausible or inconsistent lambda readings.
- Oxygen sensor heater circuit faults.
- Damaged wiring, insulation or electrical connectors.
Why Replacement Matters:
- The pre-catalytic converter lambda sensor provides essential feedback for controlling the engine's air-fuel mixture. The ECU relies on this information to make continual fuel-delivery adjustments as engine speed, load and operating conditions change.
- As a lambda sensor ages, its response may become progressively slower or less accurate without immediately failing completely. This can result in less precise mixture control and contribute to increased fuel consumption, reduced performance, unstable running and higher emissions.
- Incorrect fuelling can also affect the catalytic converter. An excessively rich mixture may allow unburned fuel to enter the exhaust system, increasing catalyst temperatures and potentially shortening catalytic converter life.
- A completely failed sensor may cause the ECU to substitute calculated values or adopt a fallback operating strategy. The engine may remain driveable, but efficiency, emissions and performance can be compromised.
- Because it is specified for the right-side, pre-catalytic converter position, correct sensor location is particularly important on engines equipped with multiple exhaust banks and lambda sensors.
- Replacing a defective sensor with this OE Match Right Lambda Oxygen Sensor helps restore accurate mixture feedback, efficient combustion and dependable engine-management performance.

Diagram ref no 29 (LEFT) / 28 (RIGHT)
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.
