Where is the lamba sensor on a Renault megane scenic?

The lambda sensor on a Renault Megane Scenic is typically located in the exhaust system. There are usually two sensors: one positioned before the catalytic converter (upstream) and another after it (downstream). To access the sensors, you may need to lift the vehicle and work from underneath or remove certain components for better visibility. Always consult the vehicle's manual for precise locations and diagrams.
