Lambda Sensors / Probes

Lambda Oxygen Sensor. Cylinder 1-3



Fits:
Porsche Cayenne 957 V6 3.6L (before catalyst)

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 21

Manufactured to OEM specifications, this lambda sensor helps ensure the vehicle meets emissions standards while allowing the ECU to continuously monitor and optimise engine operation. By accurately measuring oxygen levels in the exhaust stream, it supports efficient emissions control and helps identify catalytic converter performance issues before they become more serious.

What This Product Does:

• Monitors oxygen levels in exhaust gases after the catalytic converter
• Measures catalytic converter efficiency and performance
• Provides real-time feedback to the engine control unit (ECU)
• Supports emissions control system monitoring
• Helps maintain compliance with emissions regulations
• Assists the ECU in diagnosing exhaust and catalyst-related faults

Symptoms Of Wear Or Failure:

• Check engine light illumination
• Catalytic converter efficiency fault codes
• Failed emissions or MOT tests
• Increased exhaust emissions
• Reduced fuel economy in some cases
• Engine management warning messages
• Oxygen sensor-related fault codes
• Incorrect catalytic converter monitoring data

Why Replacement Matters:

• Restores accurate exhaust oxygen monitoring
• Ensures proper catalytic converter efficiency monitoring
• Helps maintain emissions compliance and MOT readiness
• Prevents persistent engine management warning lights
• Supports efficient engine management system operation
• Allows accurate diagnosis of catalyst and exhaust system performance
• Reduces the risk of increased emissions and environmental impact
• Maintains long-term reliability of the emissions control system
