Chevrolet Tracker Oxygen Sensor Parts Questions & Experts Answers
- Q: What is the function of the oxygen sensor in the exhaust system?A: The oxygen sensor monitors exhaust gas oxygen levels, aiding the PCM in maintaining an optimal air/fuel ratio of 14.7:1. It sends voltage signals fluctuating between 1.0-volt and 0.1 volt when warmed up. OBD-II vehicles have two heated sensors: the upstream sensor in the exhaust manifold and the downstream sensor post-Catalytic Converter. The latter gauges the converter's efficiency. Issues in the oxygen sensor circuit can trigger diagnostic trouble codes. Before deeming the sensor faulty, other impacting components should be checked. To test, measure its voltage under various engine conditions. If malfunctioning, replace using an oxygen sensor wrench, applying anti-seize to the new sensor's threads and tightening to the specified torque.
- Q: How to replace the oxygen sensor on Chevrolet Tracker?A: According to the Maintenance Schedule, it is recommended that the oxygen sensor used on 1986 Samurai models should be replaced. The sensor has threads which are connected to the exhaust manifold and has wires attached to it. One needs to unthread the sensor from the exhaust manifold after disconnecting the wire. It involves removing a wire harness and removing a sensor by unscrewing it out from a manifold. The threads should be coated with an anti-seize compound before putting it in the manifold. After torqueing tighten, hook back up the wire harness. You will need a special oxygen sensor socket for this job which can be purchased at most auto parts stores.
