Scrub the end of the sensor and remove the dirt and grime that have accumulated on its tube-shaped end. When the outside of the bulb is exposed to hot gases, the difference in oxygen level will cause the voltage to flow through the bulb. Allows install of 3 wire heated O2 sensor on cars that came with 1 wires sensors. The computer in the car is a 95 computer and i do believe that pinout 46 is the one for the sensor. Now back probe the O2 sensor’s signal voltage and the ground wire. The molar mass of molecular oxygen O2 is 32 g/mol. Any attempt to repair the wires, the connectors or the terminals results in the obstruction of the air reference and degrades the oxygen sensor performance O2 sensors use either chrome or nickel plated wires also which is more difficult to solder than per se copper. Jeep Wrangler bad O2 sensor symptoms, causes, and diagnosis. To clean the oxygen sensors, scrub each unit with your soft-bristled brush before putting them on the shop towel. first need a lab scope, then warm vehicle up, back pin the signal wire (try both). The oxygen sensor equipped with a heater has an internal heater circuit that quickly heats the sensor to the operating temperature. Do I have to rely on wire color to correctly wire up an O2 sensor?. all you have to do is disconnect and reconnect. coolant (CTS) and intake air temperature sensors (IAT), a oxygen sensor (EGO) is highly recommended, either narrow-band or wide-band, and threaded bung, and wiring and various connectors for the sensors, injectors, etc. Remove the wire harness cover, then remove the grommet.
