Oxygen Sensor: Testing and Inspection

All four sensors are identical. Inspect each in the same way.
1. Inspect the pigtail and the electrical connector for grease, dirt, corrosion, and bare wires or worn insulation.
2. Inspect the louvered end of the sensor for grease, dirt, or other contaminations.
