Delphi Oxygen Sensor P/N:ES10917
Delphi ES20165 front oxygen sensor for the 2000-2004 Volvo S40 4-cylinder 1.9L and other vehicles measures the oxygen in the exhaust gas. Its signal helps the engine computer manage the air-fuel ratio.
A check-engine light, poor fuel economy or a rough idle can mean the front oxygen sensor is wearing out, but each can come from other faults. Before you replace the sensor, rule out a damaged connector, an exhaust leak or another fault that can set the same code.
This sensor is a direct-fit replacement for the 2000-2004 Volvo S40 4-cylinder 1.9L and the 2000-2004 Volvo V40 4-cylinder 1.9L.
