What are the important considerations when servicing an oxygen sensor?

When servicing an oxygen sensor, exercise caution. Oxygen sensors have a permanently attached pigtail and electrical connector that should not be damaged or removed. Keep grease, dirt, and contaminants away from the electrical connector and sensor. Avoid using cleaning solvents as they can cause damage. Handle sensors delicately and avoid dropping them. Apply anti-seize compound during installation, unless it's a new sensor with compound already applied. Install the silicone boot correctly to prevent melting. Removing the upstream sensor may require removing the engine cover or raising the vehicle on jackstands. Disconnect the upstream sensor's electrical connector before removal. The installation process is the reverse of removal, ensuring a secure tightening. For the downstream sensor, raise the vehicle on jackstands and disconnect the electrical connector before unscrewing. Installation is the same as the upstream sensor, with optional anti-seize compound and secure tightening.

Chevrolet Equinox Oxygen Sensor

The Oxygen Sensor involved in Chevrolet Equinox is the system that adjusts the air/fuel mixture of the engine exhaust in order to achieve better performance along with less pollution. The sensor measures the amount of unburned oxygen and through comparing it to the amount of oxygen in the atmosphere, creates an electric signal that the engine control computer takes and uses to correct the fuel injector pulse width. Having a zirconium dioxide sensing element with platinum coating, the sensor works at high temperatures, switches between the rich and lean conditions to ensure the effectiveness of catalytic converters. Chevrolet Equinox vehicles normally require at least 2 oxygen sensors, one ahead of the catalytic converter and the other after it though the ahead sensor provides most of the feedback. Like the other oxygen sensors that give rich/lean signals, newer cars may come with wideband air/fuel ratio sensors. Impurities such as silicates and phosphorus reduce the efficiency of the sensors, and this indicates more emission and less fuel consumption. Maintenance and inspection of the Oxygen Sensors are critical tasks that should be carried out on Chevrole Equinox engines due to their roles in determining the correct function of the engines as well as emission control.

Each OEM Chevrolet Equinox 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.
