Diagnostic Trouble Code 0510 points to a problem with the Rear Heated Oxygen Sensor.
This sensor is mountedin the exhaust stream, just downstream of the Catalytic Converter. When the two Front Heated Oxygen Sensorsare operating properly the Rear Heated Oxygen Sensor is not used for engine control operation. It is used to monitor the condition of the Catalytic Converter. If either (or both) Front Sensors fail, the Engine Control Module uses the signal from the Rear Sensor to maintain a correct fuel/air mixture.
DTC 0510 is detected when the signal from the Rear Heated Oxygen Sensor does not reach the expected
maximum voltage threshold value.
The possible causes include ...
- Harness or connectors (the sensor circuit is open or shorted.)
- Rear Heated Oxygen Sensor
- Fuel pressure
- Fuel injectors
- Intake air leaks

its in the mid pipe behind the cat.. just jack up the rear passenger side of the car and use a 22mm open end wrench to remove it(well its 22 for the front.. just guessing it might be the same for the rear)
FYI: the rear o2 sensor doesn't affect performance on the maxima.. its just there to monitor the cat.. so there is not real rush to get it fixed
