Oxygen sensor?

P013 - Rear Oxygen Sensor not Ready - Possible short or open in the circuit or Sensor malfunction.

P044 - Rear Heated Oxygen Sensor Lean Exhaust Signal - It will set when there is an Oxygen Sensor circuit fault giving a false lean indication or When fuel air ratio is actually lean due to cacuum leak or fuel control system fault. If P013 is set diognose it first because it will cause other emission related problems.

Take care of the P013 and P044 should go away. I would check the wiring for shorts or an open then replace the sensor.
