How to Properly Replace an Oxygen Sensor on Dodge Challenger?

To prevent driveability problems after changing an O2 Sensor, you should either disconnect the PCM C-1 connector or the battery negative terminal for a short time so that the NGC relearns all of the O2 heater elements' info. Be sure not to put grease near the oxygen sensor's connector or try any soldering with the wire harness for the sensor. Both the engine's exhaust manifolds have their own heated oxygen sensors. With the sensor gone, use an 18 mm X 1.5 + 6E tap to clean the threads inside the exhaust manifold. If you are going to use your old sensor, apply a little anti-seize compound such as Loctite 771-64 or the same product; new sensors have a coating on their threads and don't need extra compound. Tighten the sensor down to 41 Nm (30 ft. lbs.), attach the electrical connector for the heated oxygen sensor, put the ride on the ground and reinstall the negative battery cable.

How to Properly Remove and Install an Engine's Oxygen Sensor on Dodge Charger?

The engine relies on two heated oxygen sensors, found one in each exhaust manifold. Cooling the engine is important before it is removed, as the exhaust manifold, exhaust pipes and catalytic converter become extremely hot during running. To start, take off the negative battery cable and have the vehicle raised to support it safely. Take care to release the electrical connector and don't pull the wire by hand. A Snap-On YA8875 or a crow foot wrench can be used to remove the oxygen sensor. The NGC learns the characteristics of the O2 sensor's heater element, therefore it is important to clear the PCM RAM before installing a new O2 sensor, by either disconnecting the PCM C-1 connector or disconnecting the negative battery cable for a minute. Take out the sensor, then clean the exhaust manifold threads with an 18 mm X 1.5 + 6E tap. Coat the original sensor threads with anti-seize compound like Loctite 771-64, but new sensors already have a coating and don't require more. Adjust the sensor to 41 N.m (30 ft. lbs.), plug the heated oxygen sensor connector back in, lower the vehicle and then reattach the negative battery cable.

Dodge Oxygen Sensor maintains the balance of combustion, reducing wastage and letting engines breathe normally. In 1914, Dodge stamped its name on the road with an all-steel body, sneering at fragile rivals and giving a note of uncompromising power and straight-ahead brute strength to all cars that succeeded it. Dodge continued to add more muscle with HEMI mills, the snake-like Viper program, and a philosophy of taking the shove instead of merely holding back. Now, Dodge vents snarls with the Fratzonic Chambered Exhaust and pumps a 600-watt roar, shedding the flex in Drag, Donut, and Sport modes, but quieting down to stealth should the driver need to sneak home undetected. Dodge never dilutes that heritage of strength and instead selects the technology that introduces grin-inducing sound or silent movement without ever concealing the unstated directness of the brand. Oxygen Sensor is located in the exhaust stream, the zirconium oxide core of which is coated with platinum to stir up a voltage that switches between rich and lean instantaneously as the hot gases pass through, giving the control computer live data to vary injector pulse width and maintain a close stoichiometric ratio to ensure closed loop efficiency and cleaner tailpipes. The sensor has two connections that run upstream and downstream of the catalyst, and the system compares the readings and identifies a failed converter before mileage drastically decreases. Oxygen Sensor ages as fuel deposits cover it, and the signal becomes lazy and causes the mixture to deviate until emissions run high and acceleration becomes dulled. Oxygen Sensor works optimally when drivers use clean fuel, seal leaks within a short time, and replace faulty ones before the engine begins to burn an excessive amount of gas.

Dodge Oxygen Sensor Parts and Q&A

Q: How to Properly Replace an Oxygen Sensor on Dodge Challenger?
A:
To prevent driveability problems after changing an O2 Sensor, you should either disconnect the PCM C-1 connector or the battery negative terminal for a short time so that the NGC relearns all of the O2 heater elements' info. Be sure not to put grease near the oxygen sensor's connector or try any soldering with the wire harness for the sensor. Both the engine's exhaust manifolds have their own heated oxygen sensors. With the sensor gone, use an 18 mm X 1.5 + 6E tap to clean the threads inside the exhaust manifold. If you are going to use your old sensor, apply a little anti-seize compound such as Loctite 771-64 or the same product; new sensors have a coating on their threads and don't need extra compound. Tighten the sensor down to 41 Nm (30 ft. lbs.), attach the electrical connector for the heated oxygen sensor, put the ride on the ground and reinstall the negative battery cable.
Oxygen Sensor, Front Driver Side
56029049AA
Q: How to Properly Remove and Install an Engine's Oxygen Sensor on Dodge Charger?
A:
The engine relies on two heated oxygen sensors, found one in each exhaust manifold. Cooling the engine is important before it is removed, as the exhaust manifold, exhaust pipes and catalytic converter become extremely hot during running. To start, take off the negative battery cable and have the vehicle raised to support it safely. Take care to release the electrical connector and don't pull the wire by hand. A Snap-On YA8875 or a crow foot wrench can be used to remove the oxygen sensor. The NGC learns the characteristics of the O2 sensor's heater element, therefore it is important to clear the PCM RAM before installing a new O2 sensor, by either disconnecting the PCM C-1 connector or disconnecting the negative battery cable for a minute. Take out the sensor, then clean the exhaust manifold threads with an 18 mm X 1.5 + 6E tap. Coat the original sensor threads with anti-seize compound like Loctite 771-64, but new sensors already have a coating and don't require more. Adjust the sensor to 41 N.m (30 ft. lbs.), plug the heated oxygen sensor connector back in, lower the vehicle and then reattach the negative battery cable.
