Lambda Sensor, AFTER Catalytic Converter. Porsche 95B Macan 2.0L Petrol 2014-18  ❭  8K0906262G

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.
