Q:HOW TO CHANGE THIS PART AND WHEN DO YOU CHANGE
A:The service engine soon light will come on and a diagnostic trouble code(s) will be stored. There may be multiple codes stored for a sensor. A fuel delivery malfunction can be the reason for an oxygen sensor to fail. A fuel injector malfunction could be the root cause for the sensor failure. Just replacing the sensor may not be a long-term solution. The instructions to replace the oxygen sensor are as follows: Park the vehicle on a level surface. Set the parking brake and open the hood. With the engine off and cool, locate the defective oxygen sensor in the exhaust manifold or pipe. If necessary, lift the front of the vehicle and support it with jack stands. Disconnect the wire connector at the defective oxygen sensor. Remove the oxygen sensor from the exhaust system. If you are installing a universal oxygen sensor, cut off the connector from the original sensor and splice the connector wires to the new oxygen sensor. Follow the manufacturer's instructions supplied with the sensor. For threaded oxygen sensors, apply anti-seize compound to the threads and install the new sensor. For flange mounted oxygen sensors, install a new gasket and tighten the mounting bolts. Reattach the wire connector from the sensor. If necessary, connect the OBD I/II scanner and erase the fault code.
