Outer Limits 4x4 Board

Hey Guys,

My mate has a patrol that has an ongoing problem that the engine light comes on and the vehicle may go into limp mode after going through water or puddles.
draining the fuel filter and resetting the engine (battery disconnection) helps but is not the solution.
The monkeys at Nissan cant help and no-one seems to know how to fix. Its either an electrical fault or water is entering the system somewhere.

Any Ideas!

leave it at the dealer, and ask them for a car to use while they fix it.

Im sure they will manage to fix it pretty fast then.

or contact Val Davis at headoffice in melbourne..

have a search, i think someone mentioned something about a connector for the ecu just above the gearbox which is prone to getting water in it.

HTH

so this is a pretty common problem then? And Nissan is aware of the issue???

Ta.

they actually replace filter or just drain,,,, draining fixed mine temporarilly then replaced to find jelly type shite in fuel and replaced and no dramas.................

my 04 3l into shop again wed for overheating again

the filter has been replaced about 5000ks ago but continues. apparently some sort of algae grows in diesel and there is a gause filter near the tank but the symptoms of this are just gradual power loss. What does ECU stand for???

engine control unit

Ive done a search but with limited info that I know about the problem, I havent found anything useful, only that the pre-02 Series 2 Patrol shit their engines.

This problem could be to do with a sensor or something near the gearbox? Has anybody come across this. My mate has repalced 2 air mass sensors, but the problem only occurs after dunking the truck. We did drain the fule lines last time (much to the disgust of my mouth as we had no siphon - diesel tastes shit!), and removed the filter, all was clean, no jelly, but still limp mode.

ANy more ideas?

You need to get the fault from the ECU. When the engine fault light comes on, you need to either take it Nissan and get them to plug the computer into it, or you need to do it yourself.

The gregory's manual for the ZD30 is quite comprehensive, but basically you need a piece of wire 3-4 inches long, and short circuit the connection plug under the steering column with the ignition on, but engine not running (terminals 1 & 8 - outside terminals on the bottom row of white plug for about 3 seconds).
Once you have done this, the engine fault light will flash in a code (long flashes and short flashes).
This will give you your fault (0707 = airflow sensor from memory, and so on). Once you have all codes, you can reset the ECU (usually taking it out of limp mode), by shorting the same terminals again, then turn ignition off.

If you are keeping the car, get the gregory's, it's got heaps of good stuff in it - including pictures of the plug etc.

Good luck.

Forgot to mention that the engine check light isn't just for the fuel filter as the manual says, it indicates about 30 odd different faults, so you really do need to check it.

Found the manual, Airflow Sensor code is actually 0102.

Thanks Manno74, my mate is trying to get a manual, so he can diagnose the real problem.
