Hi there, I've had my Outlaw Double Cab for nearly 2 years. In the last it's suffered from loss of engine power. Took it to the the dealer I bought it from but they were useless, I changed dealer to West Way in Stockport and they changed the common rail fuel injectors. This was carried out under warranty of course in May 2008. But in Dec 2008 and last week (Jan 09) the exact same problem occurred again. Dramatic loss of power while maintaining a constant speed on the motorway doing between 60 and 70 mph. On both occasions I took the Navara in to the dealer but because the fault is intermittent they can't find the fault. The engine management system doesn't acknowledge there's a problem, so the tech who hooks it up to the diagnostics rig can't see what he's looking for. ( do they not use spanners these days )
Nissan say I have 2 options, one is to leave it with them for the engineers to drive to work in - I laughed in their face 'cos I'd probably be given a f***ing micra in return.
The second option was to carry on driving it until the fault resurfaced then get it to them asap without turning the engine off. Oh joy it'd be like driving without brake lights on the M6, 70mph down to 45mph with a beemer up my ****!

Anybody else experienced this? ( yes I know everybody has had a BMW up their backside, somethings never change).

Logging off now back on 2moro.

Yup id say same as Rob, truck is going into safe mode, its the pressure sensor on the common rail which causes this action, there has been known faults with this sensor going faulty. if the sensor is not faulty then your getting a boost in fuel pressure somewhere for the sensor to be putting the truck into safe mode.

Id get them to change the pressure sensor!

Does it feel like a non turbo diesel i.e. does not like revving over 3000 and nottoo quick upto 3000??

I had this happen after I pressure washed the front of my D40, traced the fault to water in the turbo sensor connector behind the grille.

Hope this helps someone.

That wouldnt happen if they made the black slats in the grill smaller!! everything ie intercooler, rads and sensors are to "exposed" IMO.

since i put the upper upper and lower grill kit on mine theres a lot less **** getting into that area and engine bay, popped the bonnet on my dads nav last week and its like a salt bomb has gone off under there!! :lol:

Cheers for that will tell them to check the fps. Just thought though is that I bought a chip set from Tunit who specialise in diesel tuning, I connected it in series between the ecu and the engine, according to Tunit this increases the air mix with the fuel thus increasing power while also increasing mpg. also have K&N air filter fitted. I have niticed the difference but the chip may stop the ecu registering a fault with the fuel pressure sensor and also what you guys just said about it going into safe mode when detecting a boost in fuel pressure. Of course I've not mentioned this to Nissan and also removed these items when gone in for this fault. Nissan would try and void the warranty. But first time this occurred I removed chipset, set off down the road and within half a mile it happened again so maybe I'm clutching at straws. Anyway chaps thanks again.

could also be dirty MAF sensor. with K&N you will need to clean the MAF quite regularly especially if you go off road or dirt/gravel roads due to all the excess dust.

Is your truck ok without the chip on? if so this is prob the reason for the loss of power

The truck is going into safe mode. i have a similair set up. ive got the K&N panel filter with a plug and play chip also. since the temperature got colder the chip started playing up (putting the truck into safe mode) this is because the air is a lot colder and theres more off it being sucked through the k&n,so more fuel is needed, so with you already having increased fuel pressure due to the chip it takes less for it to hit its safe limit on the pressure sensor, so colder, denser air at a highger volume being dragged into the engine would cause this. either turn the chip down (or take it off till the weather gets warmer) or put the standard air filter back in and try it. you will prob find that the settings in the chip are programed for a standard truck.

One of the symptoms I had was when cruising on the motorway and then needing to accelerate and noithing would happen.

Low gear and hard pull away would sometimes result in little or no revving.

Fault cleared itself after about a week, but the weather was warm, so I supposed it dried naturally, so far not returned, but then again I have not pressure washed the front again!

I had the same problem with my 56 plate Pathfinder. It kept cutting out under hard acceleration and left a fault code. Restarting the car always cured it ... until the next time.
Nissan claimed they replaced the common rail and fuel pump, then it lost power again shortly after picking it up from the garage. I left it with the dealer again over a long weekend, hey presto it was fixed. Not sure whether it was a bad connection all along (in which case they wasted a LOT of money), or whether they actually omitted to undertake the work first time (which would be fraudulent :shock: ). I've no reason to suspect the latter as they appear to be a good dealer.

Well it went in this morning and seemed to drive fine on the way to the dealer's :? , it's had its 90 000 service (a big one so they say :shock: ) a few miles early and it's been plugged into the machine and tuned according to the dealer (I have no idea what that means) and after the test drive it runs fine so we'll see

I tried to get the filter off but couldn't shift it even with a filter spanner so drained it but no change

Driven it about for a few days and it's alot better, but not right & towed a trailer 300 miles over the weekend, up hill when you put your foot down it seemed to die but pickup when you lifted off any ideas as the dealer doesn't seem to have any, they're going to ask Nissan
