Hello my name is XXXXX XXXXX I will be more than happy to assist you.


95% of the time it is the Crankshaft Sensor also know as the Engine Speed Sensor. Nissan has a problem with the sensor and came out with a new sensor.


Any time you get code P0725 and/or P0335 you should replace the Crankshaft and Camshaft sensors. When one goes out the other will go out or is already bad.
