Gday,
Is there anyone out there who can shed some light on engine analysis codes?
The code is P7-F/INJ TIMG FB.
the initial problem was loss of power and thought to be water in fuel but have since found there is no sender unit on the bottom of the fuel filter.
any info would be appreciated
cheers

When we had our 2008 3ltr crd patrol I would phone the Nissan State Office if I wanted any info.
When you phone ask for the Technical Section.
You get better results from the State Offices than phoning the Nissan Head Office.
We had crap fuel in our patrol and it lost power and it didn't show up on the Engine Management System.
Cheers

From the Emanual I recommended to download.
TROUBLE DIAGNOSIS FOR ‘‘F/INJ TIMG F/B’’ (DTC 21)
Injection Timing Control Valve
The injection timing control valve is built into the electronic fuel
injection pump. It controls the timer piston to change the fuel injection
timing.
The timing control valve is a solenoid valve located in the line
between high-pressure chamber and low-pressure chamber. It
changes fuel pressure in the high-pressure chamber.
When current flows through the solenoid (the solenoid turns ON),
the timing control valve opens, advancing fuel injection timing.
When current does not flow through it, the timing control valve
closes, retarding injection timing.
The ECM emits an ON-OFF duty signal. The longer the OFFduration,
the greater the advance angle. The longer the
ON-duration, the greater the retard angle. This means that changing
the ON-OFF duty ratio makes it possible to achieve an optimal
advance angle and accurately control fuel injection timing.
Cheers

Thanks for your replies everyone.
Thats given me a few things to start looking at............
Sorry about the generic thankyou , but Im in a rush.
I dont suppose anyone has pulled the fuel tanks out of a 2000 Patrol have they? Is it a pain in the ####? Do they have a drain plug?
Cheers

"This fault code refers to quite a few things. It is telling you there is no control over timing because there is fault that can be caused by
Harness or connectors
(Electronic control fuel injection pump circuit is open or
shorted.)
Electronic control fuel injection pump
Improper fuel quality, air in fuel system or fuel restrictions"
More than likely the fuel pump..
