This Pre DPF Oxygen Sensor is located in the exhaust system before the Diesel Particulate Filter (DPF). It is a crucial electronic sensor that measures the concentration of oxygen in the exhaust gases leaving the engine.
This information is sent to the vehicle's Engine Control Unit (ECU), which uses it to adjust the air-fuel mixture for optimal combustion and to monitor the efficiency of the emissions system. A replacement is necessary when the original sensor fails due to age, contamination, or damage, leading to incorrect readings being sent to the ECU.
