What is the Function of an Oxygen Sensor in a Dodge Dakota's Exhaust System?

The oxygen sensor in a vehicle's exhaust system reacts with the oxygen to produce a voltage output that indicates the amount of leftover oxygen in the exhaust. This feedback signal is continuously monitored by the PCM to determine the required fuel injection and control the air/fuel ratio. The ideal ratio for minimum emissions and fuel economy is 14.7 parts air to 1 part fuel. The post-converter oxygen sensor is used to monitor the efficiency of the catalytic converter. The configuration of the oxygen sensors varies depending on the vehicle's emissions package. The sensor operates correctly when it has good electrical connections, sufficient air supply, reaches the correct operating temperature, and uses unleaded fuel. 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 lead. 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.
