Good morning everyone I am a new member with a problematic P12.
The symptoms are that it indicates a fault, via the MIL, sometimes several times a day but sometimes it can go for a week and show nothing. The fault indicated is P0093 which is a large fuel leak. This puts the car into limp home mode which clears on stopping and restarting. It may reoccur fairly quickly and it may not. There are no indications that anything is untoward until the MIL comes on. The only clue I have is that it was fine during the week in October when it was warm and dry and the faults started again when it got cold and wet. I am beginning to suspect an earth fault but do not know where to look. Any help or tips would be greatly appriciated. |

Never ascribe to malice that which can be explained by incompetence

Welcome to NPOC Phil,
The service manual is available on here http://www.npoc.co.uk/forum/nissan-primera-factory-service-manuals_topic29493.html
Your fault code isn't listed as far as I can see?
I can see from your new member post that you have a 52 plate 2.2DCi
It helps you attract the attention of the right people if you include the engine/fuel type in the question subject. There are 2 phases of P12, so the year also helps.
There are a few YD22 experts on here who will be able to help.
I do know there have been problems with earth straps on the P12. I believe a common one is to the gearbox (hidden under the battery).
Have a search for 'P12 earth'
Good luck getting it sorted

Thank you for your reply imckay.
Unfortunately I cannot edit my posts yet. If an administartor can allow me to do this or modify as appropriate I would be greatful. Maybe the title should read: Nissan Primera P12 2.2dCi 2002 random P0093 fault Thanks to NPOC I have the service manual and I have visually inspected to gearbox earth strap. This is intact but I have not taken it apart. |

Close to your air bix there is your boost control solenoid... Try to pull the wires out of it and get back to me.

...Its been a while..... Erm, just to the side of the boost house, there is a small actuator. The plug is square with a metal clip around it. If the wires come out of that it flags up a fuel leak.

Is that what the service manual refers to as the 'variable nozzle turbocharger control solenoid'? There are a few pics in the manual which may help Phil identify it.

Yes, I think it is.... I try not to pay attention to names as they change from model to model and it all gets confusing!

Thank you very much. I found the solenoid and on pulling the red wire it came out. It is now soldered back together and hopefully repaired. I will try and update in a couple of months.
