How Does an Oxygen Sensor Work in a Dodge Ram 2500 and Ram 2500's Exhaust System?

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.

Dodge Ram 2500 Oxygen Sensor Parts Questions & Experts Answers

Oxygen Sensor
56029049AA
Q: How Does an Oxygen Sensor Work in a Dodge Ram 2500 and 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.
