Good morning,
This code is for a short to voltage for the sensor. The most common issue is the heater portion of the circuit has the short. There is a power and ground at the connector for the circuit.

Disconnect the connector and check the voltage at pins 1 and 2 at the connector. You should have battery voltage.

Let me know the results. I attached the flow chart below for you to follow.
