Nissan Patrol Probs

Is it a 3 litre one?

Alan

when the light comes on , it logs a fault code relating to the part of the engine management system where the problem could be .
you need a scan tool to read the fault code
cheers mechpete

Gday,
Sorry, but if you do a search on 3.0lt TD Nissan youll find more info than you probably want.
And its probably all bad.

Cheers

Bruce my 03 patrol did the same thing. I was told it could be a boost problem so I fitted a boost gauge and found it was spiking at around 25psi ( bad )! I then fitted a Dawes and needle valve making boost control a manual operation. Done around 20,000km since and has had no further problems. Note.....May not be your fix. Kevin

Hi Bruce, ours has sometimes had the engine light come on, and 'runs rough'. It has been in very wet weather each time and seems to be related to the moisture. It has always self rectified quite quickly. This has happened only three times in over ten years. Was there weather wet at the time?

Hi Bruce. Have a read here: http://www.patrol4x4.com/forum/diy-modifications-accessories-40/nads-step-step-guide-102148/
Not sure I would be driving it too far without a diagnosis of the problem. Chances are that it may blow in the middle of nowhere.

I agree with freedom Seeker re [Chances are that it may blow in the middle of nowhere.] A tow job would be very expensive,( if not covered by RAA/NRMA etc) plus the cost of fixing up the vehicle. To me you could be virtually writing off the vehicle if this happens.

I ( if it were my daughter) would try and get a loan of a scan tool/cable and post it( insured) up to her and have a mechanic step her thru what is involved to do the scan.

Bruce a scangauge costs under $200 delivered to your place or her place.
Takes a few minutes to learn how to do a scan.

Plugs into the on board diagnostic port that is at the bottom of the steering colum (same as plugging a wire to your computer).

Install the gauge , read what the code is if any then put the code into google to see what it relates to.
Eg ...enter ...what does code xxxc on nissan patrol mean ?

Also a nearby garage may have a similar instrument and do the scan for you for minimal cost.
You dont need a nissan dealer as these scan tools scan many different model vehicles.
We have an unbranded workshop in our area that scans a wide variety of vehicles no problems.
All the best.

Do not buy a scan guage, it is not compatible with this model Patrol.

There are a number of reasons that you could have experienced the limp mode. dirty MAF, dirty fuel filter or the dreaded overboost issue.

Please join the Patrol 4x4 forum, there are members in Adelaide who will let you know who the local mechanics are that are experienced in the issues.

Bruce,

As your daughter works at the APY it could be a rather dirty air filter if the vehicle does not have a snorkel on it. I had the same experience with our 2003 Nissan Patrol on the Oodnadatta track and found out it was the MAF (Mass Air Filter). I cleaned the air filter best I could and purchased a can of Mass Filter Cleaner, removed the MAS filter, gave it a good spray and no further problems.

Without a snorkel the air filter fills with dust from the wheel arch very quickly on dirt roads. The link below is a photo that shows the MAS filter with wires coming out of it. It's located between the air filter and the donk. Hope this is of help.

Check the vacuum line to the turbo. If it is split you won't get any turbo boost. Also if you don't have a torx bit to suit the MAF, you can access it by removing the 4 x 10mm bolts in the inlet trunk between the air cleaner outlet and the turbo.
