RIGHT Lambda Sensor, AFTER Catalytic Converter. Porsche 95B Macan 2014-18  ❭  95B906203G

RIGHT Lambda Sensor, AFTER Catalytic Converter.
The BOSCH RIGHT Lambda Sensor, After Catalytic Converter is an OEM-quality emissions control sensor designed to monitor the oxygen content of exhaust gases after they pass through the catalytic converter on the right-hand exhaust bank. Also known as a post-catalyst oxygen sensor, it provides continuous feedback to the engine control unit (ECU) to evaluate catalytic converter efficiency and ensure the emissions control system is operating correctly.

Fits:

• Porsche 95B.1 Macan S Petrol 3.0L V6 (340Bhp) 2014-18
• Porsche 95B.1 Macan GTS Petrol 3.0L V6 (360Bhp) 2014-18
• Porsche 95B.1 Macan Turbo 3.6L V6 (400Bhp) 2014-18

Located downstream of the catalytic converter, this BOSCH sensor measures residual oxygen levels in the exhaust stream, allowing the ECU to monitor catalyst performance, detect emissions-related faults, and maintain compliance with environmental regulations. It delivers accurate readings, reliable operation, and long-term durability.

What This Product Does:

• Monitors oxygen levels in exhaust gases after the catalytic converter
• Measures catalytic converter efficiency on the right exhaust bank
• Provides real-time emissions data to the engine control unit (ECU)
• Supports emissions control system diagnostics and monitoring
• Helps maintain compliance with emissions regulations
• Assists in identifying catalytic converter and exhaust system faults
  
  

Symptoms Of Wear Or Failure:

• Check engine light illumination
• Catalytic converter efficiency fault codes
• Failed emissions or MOT tests
• Oxygen sensor-related diagnostic trouble codes (DTCs)
• Increased exhaust emissions
• 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 proper operation of the emissions control system
• Allows early detection of catalyst and exhaust-related issues
• Reduces harmful exhaust emissions
• Maintains long-term reliability and performance of the engine management system
