Hi-ya! good afternoon, this day i will write an article about Steps To Change The Oxygen Sensor On A Ford Expedition
Oxygen sensors play an important role in both engine management and emission control. When an O2 (oxygen) sensor fails, it will cause your Ford Expedition’s engine to run less efficiently. This time we will tell you What change the oxygen sensor on a ford expeditionso read on.
Your Expedition may display certain symptoms when the oxygen sensor has been damaged. Or perhaps, it may not show any signs. Often the only sign of this problem is the check engine light coming on.
How to Change the Oxygen Sensor on a 2003 Ford Expedition
The 2003 Ford Expedition makes use of two oxygen sensors, each located in each tailpipe behind the catalytic converters, to monitor the amount of oxygen that emerges in the exhaust gases.
Oxygen in the exhaust gases causes sensors to send an electrical signal to the on-board computer, which constantly adjusts the fuel mixture for optimum performance and to record and monitor emissions. A special socket is needed to remove the sensors.
- Park your Expedition on flat ground and apply the parking brake.
- Next, raise the front of the Ford Expedition and support this area with jack stands on each side of the frame.
- Trace the exhaust pipes from the engine to the rear of the Expedition. You will notice a tube on each side of the motor. They will join into a tube as you progress towards the rear area. You’ll notice the sensors coming out of the exhaust pipes at 2 o’clock on the driver’s side and 10 o’clock on the front passenger or passenger side pipes just before the pipe bends into the “Y”. ” at the point where the two tubes become one.
- Next you must disconnect the oxygen sensor in the electrical connector of the wiring harness. The sensor has a 6-inch cable attached to it.
- Put the oxygen sensor plug or socket on the same sensor by sliding the sensor’s electrical wire into the same slot in the socket, then position the socket over the metal area of the sensor. Proceed by turning counterclockwise to remove the sensor.
- Proceed to place the new oxygen sensor and screw it into the exhaust pipe hole. Through the electrical cable in the slot and locate the socket on the sensor and tighten it. Then connect the cable to the wiring harness.
