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 out for service light.
• Vehicle manufacturers recommend periodic inspection and replacement of oxygen sensor.

The Lambda Sensor, After Catalytic Converter is an OEM-quality emissions control sensor designed to monitor the oxygen content of exhaust gases after they have passed through the catalytic converter. Commonly referred to as a post-catalyst oxygen sensor, it provides vital feedback to the engine control unit (ECU) regarding catalytic converter efficiency and overall emissions system performance.
Fits:
- Porsche 95B.1 Macan Petrol 2.0L (237Bhp) 2014-18
Diagram Ref No 6
Located downstream of the catalytic converter, the sensor continuously measures residual oxygen levels in the exhaust stream. This allows the ECU to evaluate catalyst effectiveness, detect emissions-related faults, and ensure the vehicle operates within manufacturer emissions specifications. Manufactured to OEM standards, it delivers accurate readings, reliable performance, and long service life.
What This Product Does:
- Monitors oxygen levels in exhaust gases after the catalytic converter
- Measures catalytic converter efficiency and performance
- Provides real-time data to the engine control unit (ECU)
- Supports emissions control system diagnostics and monitoring
- Helps maintain compliance with emissions regulations
- Assists in identifying catalyst and exhaust system faults
Symptoms Of Wear Or Failure:
- Check engine light illumination
- Catalytic converter efficiency fault codes
- Failed emissions or MOT tests
- Increased exhaust emissions
- Oxygen sensor-related diagnostic trouble codes (DTCs)
- Engine management warning messages
- Incorrect catalytic converter monitoring data
- Potential reduction in fuel economy in some applications
Why Replacement Matters:
- Restores precise exhaust oxygen monitoring
- Ensures accurate catalytic converter efficiency assessment
- Helps maintain emissions compliance and MOT readiness
- Prevents persistent engine management warning lights
- Supports correct operation of the emissions control system
- Allows early detection of catalyst and exhaust-related issues
- Reduces harmful exhaust emissions
- Maintains long-term reliability of the engine management and emissions systems
