Delphi Oxygen Sensor P/N:ES20045
Delphi ES20039 oxygen sensor for the 2001-2004 Ford Escape 4-cylinder 2.0L and other vehicles measures the oxygen in the exhaust so the engine computer can adjust fuel delivery. This Delphi oxygen sensor is built to OE standards.
A check engine light, rough running or poorer fuel economy can mean a worn oxygen sensor, but exhaust leaks or damaged wiring produce similar symptoms. With the engine off and cool, look over the sensor's wiring and connector for damage first, and leave the sensor test itself to a shop.
The listing covers a wide range of Ford, Mazda and Mercury models. It is a direct-fit oxygen sensor replacement for the 2001-2004 Ford Escape 4-cylinder 2.0L, and an oxygen sensor for the 1996-2000 Ford Explorer V6 4.0L and the 2000-2003 Ford Focus 4-cylinder 2.0L. This listing is one sensor, and a vehicle takes one or two depending on the model and year. Open the "Vehicles it fits" section to check your exact model and engine, since the front or rear position also depends on the vehicle.
