Where is the lambda sensor on a 2 liter Mk III mondeo tdci?

On a 2-liter Mk III Mondeo TDCi, the lambda sensor, also known as the oxygen sensor, 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 upstream sensor, you may need to raise the vehicle for better visibility and reach. Always consult the vehicle's repair manual for specific details and guidance.
