The P0136 is a fairly straight forward code pointing to a fault in the Heated Oxygen Sensor for Bank1 Sensor2. Inspect the electrical connector and wire harness to the sensor for any loose, broken or melted wires. If the visual inspection checks ok, replcing the sensor should solve the problem. These ar fairly common wear and tear items. Bank1 is the passenger's side, and sensor2 means it's behind the converter. There is a special tool - Oxygen Sensor Socket - that will make the removal/install much easier. You can usually rent this tool at local "big chain" parts store.
