p3027

getting cel for heater element for sensor 1 bank 2. absolutely certain it is not the sensor itself. narrowed it down to the connector pin(s) being loose, but not sure which one. already ordered and new connector.
can someone decode for me the five colored wires of the bosch sensor?
which ones would trip the p0327?
I read the data from the obd and it's reading low on the temp of the heater element of the sensor.

Really? the colors are indicated by the colored rectangular boxes next to each wire in addition to the letters (which I admit need some german)

For bank 2, the lead from the fuse to the heater is red, the lead from the heater to the DME is white and blue (WS/BL). Pins 3 and 4 on the connector.
The DME switches pin 3 to ground and monitors the current flowing through it.
