How to Maintain and Fix Oxygen Sensors on Dodge Neon?

You should raise and secure the vehicle before approaching the oxygen sensors. To remove the sensor from the upstream position, take it out by first unplugging its sensor connector and using a YA8875 or similar crow foot wrench made by Snap-On. When you've removed the manifold, clean its threads using an 18 mm X 1.5 + 6E tap and if applying the old sensor, coat the threads with an anti-seize product such as Loctite(R) 771-64 or an equal version. Lift the vehicle, take off the electrical connector, unplug the sensor harness from the body clips and move the downstream sensor to accessible location. Remove the sensor by using the same crow foot wrench designed for oxygen sensors. As before, use manufacturing oil to clean the manifold threads and spray anti-seize on them if you decide to reuse the original sensor. New sensors arrive with enough coating not to need anything further during installation. Using the wrench, tighten the upstream sensor to 28 Nm (20 ft. lbs.), connect the sensor and then lower the vehicle. The downstream sensor goes next. Tighten it with your wrench until it reaches 28 Nm (20 ft. lbs.), reattach the electrical harness from the clips on the body, plug in the electrical connector and lower the vehicle.

How to Replace the Upstream 1/1 Oxygen Sensor on Dodge Neon?

Prior to changing the upstream 1/1 oxygen sensor, raise and support the car, then take out the connector from the sensor. Wear a Snap-On tool YA8875 or equivalent gauge-face wrench to pull out the sensor. After removing the old exhaust manifold, clean its threads with a 18 mm X 1.5 + 6E tap. Should you use the same sensor, put a dab of Loctite 771-64 or its equivalent on the threads. New sensors come covered in compound and don't need any additional application. Attach the sensor with a crow foot wrench, tightening it to 28 Nm (20 ft. lbs.) and then reattach the connector and place the vehicle on the ground.

The Oxygen Sensor in the Dodge Neon cars is used to measure the residual oxygen that exists in the exhaust system since this is used to adjust the air/fuel ratio in bid to reduce on emissions. It produces voltage signal proportional to the level of Oxygen hence the engine control computer can vary the fuel injector pulse width. This feedback mechanism makes the engine work in what is called a "closed loop" thus improving catalytic converter effectiveness. A standard Dodge Neon will employ electrical oxygen sensors, in many models employing zirconium dioxide, that can be of the narrow-band or wide-band variety. Narrow-band sensors deliver switching signals rich/lean whereas wide-band sensors offer a variety of mixtures in the air-fuel mode. These sensors may also get worn out due to contamination issues thus increasing the amount of emission and decreasing the fuel economy. The Oxygen Sensor of the vehicle requires constant check-up and service in order to perform at its premier capacity.
