Tools That You’ll Need

  • 7/8″ wrench or O2 sensor remover wrench
  • Two or more 18mm non-fouler (NF) adapters

Step #2: Remove the Sensors

  • Then, grab a 7/8″ wrench or a suitable O2 sensor remover wrench to detach them. You’ll need to use some force to do that. Note that they can get stuck due to rust or dirt.
  • If the sensors are hard to take out, apply penetrating lube to help loosen them up. This way you can easily unbolt them. According to one user in the F150 Forum, you can use WD-40 for the best result.
  • Once all the O2 sensors loosen up, carefully unscrew and remove them from their positions in the exhaust system.

Step #3: Insert the Non-Fouler Adapter onto O2 Sensors

  • Next, follow the same steps for the other oxygen sensor located on the opposite side of the exhaust system.

Step #4: Reinstall the O2 Sensor and Wires

  • After preparing both sensors, reinstall them into their respective positions on the exhaust pipe. Ensure they are securely threaded in.
  • Then, plug the oxygen sensor wires back into the wiring harness, ensuring they are securely clipped in place.

Step #5: Reset the Computer

  • Once you installed the O2 sensors, open the car’s hood and then disconnect the battery.
  • After that, you’ll need to wait for some minutes.
  • Then, reconnect it and close the hood.

Note: After bypassing the O2 sensors, you should connect the scan tool to your car and clear the engine error codes.
