Chevrolet Traverse Oxygen Sensor

The Oxygen Sensor in Chevrolet Traverse vehicles is used in assessing the quantity of unburned oxygen in the engine exhaust to help ensure that the air-fuel mixture is as near perfect as possible, and to reduce emissions to the utmost level. It produces a voltage signal depending on the measures of this gas in order that the engine control computer can alter the fuel injector timing. This feedback mechanism allows the operation of the engine to be in the "closed-loop," resulting to effective catalytic converter. Chevrolet Traverse models can have zirconium dioxide oxygen sensors and can also have upstream and downstream sensors. The first one is an upstream sensor, which informs the engine about the state of the air-fuel mixture for immediate correction; the second one serves to control the performance of the exhaust gas converter. Some of the models can come with the so-called wideband air/fuel ratio sensors where the range of measurements is wider than in the case of narrow-band sensors. Both types are vulnerable to contamination and age-related degradation and will develop a decline in efficiency and an increase in emissions if the problem is not solved.

Each OEM Chevrolet Traverse 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.

When servicing, handle the sensor carefully, avoid damaging the attached pigtail and connector, and keep contaminants away. Don't use cleaning solvents and ensure the silicone boot is correctly positioned. To replace, note there are four sensors; one in each manifold and one after each Catalytic Converter. For upstream sensors, remove the engine cover, disconnect the connector, remove the sensor, apply anti-seize compound to threads if reusing, and install securely. For downstream sensors, raise the vehicle, disconnect the sensor, unscrew it, apply anti-seize if reusing, and install securely.
