Changing the Oxygen Sensor in a Chrysler Sebring

Save

Eventually your Chrysler Sebring's oxygen sensor will go bad and need to be replaced. The oxygen sensor regulates the oxygen-to-fuel ratio in your vehicle. It also controls your gas mileage. It senses when more or less oxygen needs to be pumped into the fuel lines. If it fails, your Sebring will run poorly and won't get very good gas mileage. Knowing how to change it yourself can save you money.

Things You'll Need

  • 7/8-inch wrench
  • WD-40
  • Anti-seize paste
  • Crimp connectors
  • Locate your Sebring's oxygen sensor on the pre-catalytic converter. This is located near the front right wheel well of your vehicle.

  • Remove the large air-intake pipe that runs from the air box to the rear turbo. Then remove the two smaller air pipes that run from the air box to the blowoff valves. This will give you access to the oxygen sensor. Soak the old oxygen sensor in WD-40 to loosen it.

  • Remove the old oxygen sensor, using the 7/8-inch wrench. Find the stock sensor wire near the engine-loop lift. This will be by the firewall of your Chrysler Sebring. Splice the stock sensor wire and connect it to the new oxygen sensor's wire, using crimp connectors.

  • Apply some anti-seize paste to the threads of the new oxygen sensor. Be careful not to get any of the paste on the sensor itself, or it will be ruined. This makes for easy removal of the sensor next time.

  • Screw in the sensor by hand. Use the wrench to fully tighten the oxygen sensor so it cannot be removed by hand. Replace the air pipes to the correct valves again.

Tips & Warnings

  • You can use a soldering iron instead of crimp connectors to connect the wires.
