Oxygen Sensor: Testing and Inspection

Heated Oxygen Sensor (HO2S)

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 lowered end of the sensor for grease, dirt, or other contaminations.
