Description

001 540 46 17 – Mercedes-Benz Oxygen Sensor (Lambda Sensor)
This high-precision sensor is mounted in the exhaust system, typically in the downstream position (after the catalytic converter) on either the left or right side. It measures the residual oxygen content in the exhaust gases to monitor the efficiency of the catalytic converter and provides feedback to the Engine Control Unit (ECU). This allows the vehicle to maintain optimal fuel-to-air ratios, reduce harmful emissions, and prevent engine performance issues.
