How often should you change 02 sensor?
every 60,000 to 90,000 miles
All cars and trucks that were made in the last fifteen years should have their O2 sensors replaced every 60,000 to 90,000 miles. Replacing your sensor at these intervals will lower the level of pollution that your vehicle emits while playing a preventive role in the cause of damage to the vehicle.
Where are the O2 sensors on a Hemi V8?
Figure 1 illustrates the locations of the four O2 sensors used on the 6.1L HEMI® V8 engine. 1. Raise and support the vehicle. 2. Disconnect the wire connector from the O2 sensor wire connector. 3. Remove the O2 sensor with the appropriate oxygen sensor removal and installation tool. 4.
How do you replace the O2 sensor on a Dodge Ram?
The red arrow points to the locking tab. If you are sure you will not be using the sensor again, you can cut the connector plug off and slide a 22mm box-end wrench onto the sensor. Otherwise, you will need the appropriate oxygen sensor socket. It will take some force to break the sensor loose. Turn the sensor in a counterclockwise direction.
When to reset the ECU after changing an O2 sensor?
Sometimes an O2 sensor fails, and you need to replace it. Once you’ve replaced your vehicle’s O2 sensor, you’ll need to reset the ECU so it can properly gather information from the new O2 sensor.
Can a bad oxygen sensor cause a check engine light to come on?
The trouble codes associated with the OBDII scan will reveal which sensor is at fault and why it is bad (at least what the computer thinks is wrong). It is very rare for there to be a problem with an oxygen sensor, and not have the check engine light come on. Here are the most common symptoms of a bad oxygen sensor in your Ram:

How does an O2 sensor work on a Dodge Challenger?
Figure 1 shows a typical O2 sensor that is used in a HEMI® engine equipped Dodge Challenger (LC body). By monitoring the oxygen content in the exhaust stream, this sensor produces a voltage that is inversely proportional to the amount of oxygen in the exhaust.
