• Q: How to replace the Heated Oxygen Sensor (HO2S1) on 2006 Chevrolet Aveo?

  A: When replacing an ho2s1 you should start by disconnecting the negative Battery Cable with necessary precautions. To perform the front heated Oxygen Sensor connector removal you should handle it delicately while keeping the pigtail attached to each device to maintain operational accuracy of sensors. Handle the Oxygen Sensor with care to prevent damage and always maintain a clean condition for the in-line electrical connector along with the louvered end. Any sensor damage requires a replacement of the Oxygen Sensor unit unless otherwise instructed. Keep contact cleaner away from all sensor and vehicle harness connectors during servicing and maintain both the sensor pigtail and harness wires free from exposure or damage. Engine power degradation will occur if the Oxygen Sensor ground wire remains damaged or bent since it creates sharp bends along the lead wires. The peripheral connector seal on vehicle harnesses needs attention to prevent water leaks so use packard's crimp and splice seals terminal repair kit for repairs without soldering methods. The operator should pull out ho2s1 from the Exhaust Manifold during a period when engine temperature reaches 48°c (120°F) for streamlined removal procedures. The installation of the new ho2s1 requires a specialized thread coating of liquid graphite and glass bead anti-seize compound that makes uninstalls easier in the future. Apply the tightening torque of 42 n.m (31 lb ft) when installing the ho2s1 to the Exhaust Manifold before connecting its connector and reattaching the negative Battery Cable.
