Installing an Oxygen Sensor in a 2007 2.3L Ford Ranger
- 1). Park the 2007 Ford Ranger on level ground. Engage the parking brake and place wheel chocks behind the back wheels.
- 2). Raise the front of the Ranger with a floor jack. Sit jack stands under the frame rails and lower the Ranger until the stands support its weight.
- 3). Crawl under the truck and locate the heated oxygen sensor -- the electrical component going into the exhaust pipe directly behind the union between the exhaust manifold and the mid-pipe.
- 4). Trace the heated oxygen sensor's wire up until you meet the wiring harness. Press the locking button and unplug the wiring harness.
- 5). Remove the oxygen sensor using an oxygen sensor socket and a ratchet.
- 6). Hand-tighten the new oxygen sensor into the exhaust pipe and tighten it to 30 foot-pounds with an oxygen sensor socket and a torque wrench.
- 7). Plug the oxygen sensor wire into the wiring harness on the Ranger.
- 8). Raise the Ranger with a floor jack and slide the jack stands from under it. Lower the Ranger to the ground.
