How to test and replace an oxygen sensor?

The oxygen sensor is a device that produces a voltage when exposed to oxygen in the exhaust gases. It is in the exhaust system and can be heated internally for faster reaction. The sensor produces a voltage between zero and one volt, with a low voltage indicating a lean mixture and a high voltage indicating a rich mixture. The stoichiometric air to fuel ratio causes the voltage to fluctuate.

Cadillac Fleetwood Oxygen Sensor

The Oxygen Sensor found in Cadillac Fleetwood cars is employed to ascertain the air/fuel ratio and oversee the mixture of unburned oxygen in the exhaust. This sensor, types of which can be based on the BTM or DALG sensors, utilizes the differences of oxygen to create a voltage signal that helps the engine control computer mixtures in order to have the optimal output and the minimum emissions. Generally, Fleetwood models have two oxygen sensors located before and after catalytic converter and the sender before fuel injector usually serves as a feedback. These are high temperature sensors and are prone to degrading due to contaminant exposures and hence reduce the fuel efficiency and decrease the emission standards. Instead some newer vehicles may include Air/Fuel Ratio sensors which apparently have a wider measurement range for higher accuracy. It is crucial to perform scheduled and routine checks to prevent several flaws associated with the sensors and an auto's performance.

Each OEM Cadillac Fleetwood Oxygen Sensor we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
