Installing an Oxygen Sensor in a 2007 2.3L Ford Ranger

Through the 1970s, Ford offered a compact pickup known as the Courier. Ford did not manufacture the Courier; instead Ford imported it from Mazda. In the 1983 model year, Ford released the American-built Ranger. The 2007 Ranger came standard with a 2.3-liter, in-line four-cylinder engine that produced 143 horsepower. The 2007 Ranger used a heated oxygen sensor to measure the amount of air and fuel coming from the engine's combustion chamber to help regulate emissions. When this sensor fails, a check engine light appears on the dashboard. Replacing the heated oxygen sensor is relatively easy

Instructions

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.
