I am getting this error code telling me that there is something wrong with the O2 sensor. After connecting to the truck, I get two error codes, saying that data is being transfered but it is above operation range. I tested the power coming from the wiring harness and is registering around 13.7 volts. I'm not too sure what to do from here, and will be replacing the O2 sensor just to be sure thats not the problem.

The second error code is telling me that heat bank sensor is too low in voltage, or there is an open circuit. I have yet to determine how to check this.

Any help or assistance would be appreciated.
