What Role Do Oxygen Sensors Play in a Chrysler 300?

Oxygen sensors play a vital role in monitoring the air/fuel ratio and catalytic converter efficiency. There are four sensors, two upstream in the exhaust manifolds and two downstream behind the converters. The pre-converter sensor provides feedback to the PCM to adjust the fuel injector pulse width and control the air/fuel ratio. The post-converter sensor monitors the efficiency of the converter. An oxygen sensor requires good electrical connections, proper air circulation, correct operating temperature, and unleaded fuel to function correctly. When replacing a sensor, use an oxygen sensor socket and clean the threads before installation. After replacing, disconnect the battery for a few minutes to allow the PCM to learn the new sensor.

Chrysler 300 Oxygen Sensor

Chrysler 300 Oxygen Sensor is responsible for maintaining checks on the amount of oxygen that is not burned in the exhaust of the car's engine in order to enable the engine control computer adjust the air to fuel mixture adequately to help in the enhancement of the performance of the car and reduced emission. The sensor uses zirconium dioxide as the sensing material layered with platinum, and its function is to produce a voltage signal that corresponds to the oxygen content of the exhaust gas hence determining the condition rich or lean. Oxygen sensor is usually installed in the Chrysler 300 vehicles; minimum two - one before and after catalytic converter; the upstream is preferred by the engine control system for feedback. High operating temperatures and contamination over time of the sensor are some of the causes of the increased emissions and reduced fuel efficiency for vehicles using the sensor. There is a difference in today's cars, an air/fuel ratio sensor is sometimes employed rather than the oxygen sensor, because the former offers a broader scale of measurement for the air/fuel mixture.

Looking for affordable and high-quality auto parts? Then you have already arrived at the proper online shop. We offer all Chrysler 300 Oxygen Sensor at great affordable prices. Moreover, all genuine Chrysler 300 Oxygen Sensor come with a manufacturer's warranty. In the long run, you would realize you have saved a lot of trouble and money with OEM parts from here.
