GM 5613719 Sensor Asm,Oxygen

The exhaust oxygen sensor, or 02S, is located in the exhaust pipe and aims to measure the amount of oxygen in the exhaust gas, Newer models of the sensor have a heated element different from the typical sensors. It functions to map the air/fuel mixture that is supplied to the engine, the oxygen that combines with the sensor to produce voltage, detectable by the ECM/PCM that ranges from 0.1 volt in high oxygen lean mixture to 0.9 volts in low lean oxygen. It is difficult to test the sensor when you don't have scan tools, and codes 44, 45 or 131-134 do not mean that the sensor is bad, as it can mean that such things as a dirty air filter of a vacuum leak. Due to the fact that the electrical pigtail and connector are installed permanently, contamination of this sensor is strictly prohibited. It is recommended that cleaning solvents should not be used and care should be taken not to damage the engines particularly if the actual temperature is less than 120F / 48C. There is a recommended application of a heat riser solvent every time the sensor is removed, and it should be changed after 30 000 miles The steps involved are finding the sensor, unclipping the electrical connector, applying of heat riser solvent and unscrewing the sensor. For installation, the new sensor's threads have to be protected by an electrically conductive anti-seize compound, and then the threads are to be tightened to 30 fl. lbs. Torque specified was confirmed without overtightening to 42 Nm and electrical connector was re connected in a way that the pigtail was not strained.

In L4 engines, the oxygen sensor is a screw-in one located at the exhaust manifold and in V6 engines, it is on the exhaust pipe. For this reason, it is harder to unscrew the sensor when the engine is cold and it would be better if you did it while the engine is operating. In that case, jack up the front of the vehicle and rest it on jack stands to create enough room for your work. On L4 models, extract air cleaner. Oxygen sensor electrical connector should be removed by detaching its terminals. Apply a penetrating oil to the threads of the oxygen sensor during installation ensuring that it penetrates for approximately 5 minutes. Unscrew and remove carefully. Be careful not to damage threads in exhaust manifold/pipe while removing it. Before installing new sensor, coat its threads thoroughly with an anti-seize compound then install it properly. Torque carefully to 30 ft-lb (4.1 m-kg). Reconnect electrical connector to sensor itself as before mentioned. After replacing oxygen sensor reinstall air cleaner on L4 models and lower car on V6models to ground level.When replacing an oxygen sensor, always reset 'sensor' light on dash board panel.
