How are wires used to heat up O2 sensor?

These wires serve to heat up the O2 sensor to bring it up to operating temperature via a resistance-based heating element. To test, set the multimeter to resistance mode and use it to probe and figure out which wires register a resistance (usually 4-6 Ω).

Do you need a color code for an O2 sensor?

It seems that everyone and their grandmother has a different color-code convention for 4-wire O2 sensors, which complicates matters when one is trying to wire up a replacement “universal” O2 sensor. Is it possible to determine signal-wire polarity on a 4-wire O2 sensor without relying on wire color-coding?

What does the prefix HO2 mean on an oxygen sensor?

Sensors are normally described with the prefix HO2S meaning Heated Oxygen Sensor and followed with bank and position number.

What’s the generic code for an oxygen sensor?

If you ever need specific in depth code help, use the “Get Help” link and we can run down the basics with you as needed. The codes that may give you more of a run for your money are the PO171-P0175 generic (or similar manufacturer specific) codes.

What are the abbreviations used in electrical documents?
