GMC Terrain Oxygen Sensor
The Oxygen Sensor in GMC Terrain appears to be very important because it helps the vehicle regulate the air/fuel mixture in the engine exhaust for efficiency and low emission. The sensor compares the amount of oxygen in the exhaust with the amount of oxygen in the atmosphere, and produces a voltage signal that will signify a rich or a lean condition. This feedback enables the engine control system to vary the fuel injector pulse width in the most optimal manner triggering the catalytic converter for less emission. GMC Terrain vehicles commonly use two oxygen sensors located in different positions, hence, one is the upstream oxygen sensor that primarily feeds the information to the engine control computer. Located at the inlet air temperature sensor, the sensor is exposed to high temperatures and may degenerate due to formation of contaminants which in turn augments emissions and decreases fuel economy. There are models of cars where air/fuel ratio sensors are used instead of oxygen sensors and these are likely to be more flexible in terms of what they are able to measure in terms of air/fuel mixtures.
Each OEM GMC Terrain 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.
GMC Terrain Oxygen Sensor Parts Questions & Experts Answers
- Q: What are the important considerations when servicing an oxygen sensor?A: 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.
