O2 sensor wiring

The 2010 Dodge Caliber O2 sensor wiring has four wires: two white, one gray, and one black. The wires are typically color-coded, so you should be able to match them up with the wires on the replacement O2 sensor.
Here is how the wires are typically connected:

• White wire: Sensor signal wire
• White wire with black stripe: Sensor signal ground wire
• Gray wire: Heater power supply
• Black wire: Heater ground

You can use a multimeter to confirm the correct wires if you're unsure.

When that code shows up, it normally means that the O2 sensor is bad, or there is a bad connection or burnt wire. All of which are corrected with replacement of the O2 sensor.

look under truck and follow exhaust system from front towards rear the o2 sensor 2 is the sensor after he cat converter it looks like a tube with a wire connection mounted on top of exhaust pipe disconnect connection and unscrew sensor replace and reconnect

The pink and black-white wires are for the heater, the other two are for the sensor circuit.
If you can tell me which sensor I can get the colors for you.

You can not connect to the heater wire or ground,
so I guess the output or sensor wire

I wouldn't do that, because your not supposed
to load that wire, or you run the chance of ruining
the O2 Sensor.

Forget it
Why do you need to know AFR anyway !

Weld in a separate bung for that device

You do not install a UNIVERSAL O2 Sensor

You install a Bosch OEM Sensors

Why would you even buy such a thing?

Go to NAPA, buy the correct sensor,
screw it in,plug in the connector,your done

You have an incorrect O2 sensor. It will not work. A correct sensor will plug in without any problem. If you bought the sensor at a parts store, you need to return it, and exchange it for the right part.

Follow the exhaust pipe to beyond the catalytic converter. The "rear" or down stream O2 sensor is usually on top of pipe behind the converter. Follow the wire from it to its disconnect plug andf unplug it. Use the correct size open end wrench to remove the sensor. Reverse to istall replacement. You really don't need a diagram - just your mark 1 eyeballs.

your o2 sensor hooks into your exhaust system. where it goes into the exhaust their will be a wire connector somewhere close by unless it melted away or is gone you wont see where it goes into the computer

it might be easier picking up a plug at a salvage yard then just connect to the correct colors,if you have four wires two should be black and two white,
