Figures 5 and 6: By looking at a wiring diagram, here provided by In Chrysler vehicles, four wire oxygen sensor heater circuits tend to be.Water getting inside the heated oxygen sensor connector can caused the heated oxygen sensor fuse to blow, which is a very common problem for this type codes. Before replacing the sensor, check for the condition of the heated oxygen sensor fuse and connectors.

There is a factory service bulletin for the Chrysler Chrysler Factory. Dec 15,  · This is a 4 wire sensor, 2 for the heater and 2 for the sensor output.

There are 2 black wires, 1 white and 1 purple or blue (to a color blind person). Here is what I found in my FSM for the / upstream O2 sensor from the wiring diagram.

On the front O2 Sensor, the signal wire s Purple.

On the rear O2 Sensor, the signal wire is Purple and White. (You will probably have to look at the wire colors on the main harness side of the O2 Sensor connector, not on the sensor itself.).

Do I have to rely on wire color to correctly wire up an O2 sensor? Ask Question.

As the O2 heater is resistor-based, polarity is not a concern here. Note down which two wires correspond to the heater circuit and proceed to Test 2.
