The first image below will give you an idea of where the sensor is located.
The second image provides instructions on how to access the sensor.
The sensor can be checked with a volt/ohm meter. Remove the wires from the sensor and measure resistance across the leads of the component. The resistance across the two terminals should be 1080 ohms at room temperature.
If the resistance is way off, the sensor will need to be replaced. Since you the fault code is indicating a shorted sensor, your resistance will likely be close to zero or very low.
The oven sensor is part number 8273340 and can be ordered from
