Code P1137 Subaru Description
The Engine Control Module (ECM) supplies the pumping cell with current so that sensor output voltage from the reference stays constant.
When the reference cell is lean, a positive current is used to pump oxygen out the cell.
When the reference cell is rich, a negative current is used to pump oxygen into the cell.
When the reference cell is at lambda 1, there will be no current applied to the pumping cell. The amount of current supplied is proportional to the amount of oxygen in the exhaust gases. The ECM uses the amount of current as a signal. The ECM uses the signal to calculate the actual air to fuel ratio. The injection duration is altered accordingly.
The sensor operates correctly only when it reaches a certain temperature. The heating element brings the sensor up to operating temperature quickly.

- Faulty Front Oxygen A/F Sensor 11
- Front Oxygen A/F Sensor 11 harness is open or shorted
