Lambda Sensor, AFTER Catalytic Converter.

The BOSCH 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 BOSCH 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. 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
