unknown ECU code

When I check the code for the check engine light with a code scanner it comes up "P0150" What does that mean? I cant find the meaning anywhere. Im probably stupid but I cant figure it out.

Front heated oxygen sensor

What's so "unknown" about it..

Right from the ECU sticky

P0150 = 0303

0303
Diagnostic Trouble Code 0303 indicates a problem with the front Oxygen Sensor on the left cylinder bank. The left bank is also called the front bank. It is cylinders 2,4,6. A normal signal sweeps back and forth between 0.2 volts and 0.8 volts. This malfunction was detected when the Engine Control Module received a signal from the sensor which was a constant value of approximately 0.3 volts.

Possible causes include ...
- Harness or connectors (the sensor circuit is open or shorted).
- Defective Oxygen Sensor

haynes manual - P0150 - 0303 : Upstream oxygen sensor or circuit fault (left bank) good luck with it !
