Please continue with your search for an expert to answer my question.
I disconnected the battery for 10 minutes, On restart, the engine fault light still came on, and the engine cut out again after about 10 seconds.
The fault codes are 0141 and 0143.
Hope this helps!
Unfortunately I do not have a code reader, so I will be taking it into a Nissan dealer tomorrow for diagnosis.
For the moment I do not need any more info, and thanks for your time.
