Dodge Ram 2500 Oxygen Sensor
Basically, the Oxygen Sensor available in Dodge Ram 2500 vehicles is used to check the proportions of air and fuel in the engine exhaust. Analyzing the amount of the unburned oxygen and the atmospheric oxygen, the sensor produces the voltage signal, which is necessary in order to adjust the mixture by the engine control computer in order to increase the performance of the engine as well as to decrease the quantity of the emission. Mainly manufactured from zirconium dioxide, the sensing component incorporates a layer of platinum The sensor is designed to function at high temperatures it switches between rich and lean conditions to continue stimulating the catalytic converter. Models like the Dodge Ram 2500 have at least 2 oxygen sensors, one before the catalytic converter and the other after to feed back to the engine control. That is why in addition to the traditional oxygen sensors, some vehicles could have an air/fuel ratio sensor which has a greater range and gives better results than the average sensor. Independent of these effects, it is clear that the emissions and fuel consumption will rise while the oxygen sensors' function should be often monitored and maintained to not cause any problems with the engine.

Dodge Ram 2500 Oxygen Sensor Parts Questions & Experts Answers
- Q: How Does an Oxygen Sensor Work in a Dodge Ram 2500's Exhaust System?A: The oxygen sensor in a vehicle's exhaust system reacts with the oxygen to produce a voltage output that varies depending on the oxygen content. This feedback signal is used by the PCM to determine the required fuel injector pulse width and control the air/fuel ratio. The pre-converter oxygen sensor provides this feedback, while the post-converter sensor is used to monitor the efficiency of the catalytic converter. The PCM operates in an open-loop fuel control mode until the sensor reaches its operating temperature of around 600 degrees F. The sensor requires good electrical connections, air circulation, correct operating temperature, and unleaded fuel to operate correctly. The PCM can detect sensor problems and set Diagnostic Trouble Codes. To replace the oxygen sensor, raise the vehicle, locate the sensor and disconnect the electrical connector, remove the sensor using a wrench or oxygen sensor socket, clean the threads, and apply anti-seize compound if reusing the old sensor. Installation is the reverse of removal.
