Hi all, after some advice, i have a 2007 Holden Rodeo Turbo Diesel. i have had it at the mechanic a few times and an undefined code comes up.

My Problem,
It keeps derating... it loses power (the engine keeps running) but wont rev over 1000. i turn it off and back on and is good, engine light stays on for a few days.
has anyone else had this problem?

Has the mechanic or anyone else checked the fuel filter for contamination?

Do you know when ie, how many KM's ago the filter was replaced?

When running, has the fuel pressure been checked by fitting a gauge to the water drain point and turning on the filter drain?

Many of the earlier ones had the fuel pressure regulator develop a fault and low fuel pressure is the result. Fuel pressure should be around 6 psi.

If faulty ie, low pressure, hardly any, then this may be what you require.

I think this is correct, I have not purchased one and this is the info received from someone else.

Part number of removed pressure regulator: GM8-98042316-0

New Kit
Part number: GM8-98145453-0
Part name: Kit Fuel Pressure 4JJ1

This is a KIT for the replacement of the above regulator. The regulator bolts onto the rear of the High pressure pump.
It may be the problem. Just a bit hard to tell from this distance.

Hi Ross,
Fuel filter was changed last week and apparently it was clean.

haven't had any pressure checked but the codes that came up this time was saying low pressure.

will ask them to check that for me.

This is the first diesel i have owned and dont know of a good diesel mechanic

Hi Mel,

Your symptoms are exactly what i experienced with my Nissan Terrano II 2.8 Inter-cooled Turbo Diesel.

It turned out to be a dirty MAF (mass air flow sensor), once this was replaced back to full revs.

If cleaning does not fix then you will have to replace.

cheers Rob

I actually had the same problem in my 05 Rodeo dual cab turbo diesel a few yrs ago ,, turned out to be a combination of : water in the fuel trap : dirty MAF sensor and of all things that the AUTO gearbox fluid and filter had NEVER been changed /serviced even though the log book had been 'ticked' ,,,, process of elimination with plenty of frustration finally resolved the problem ,,, water in the trap an easy fix , MAF sensor an easy fix and if it continues try the BOX……..

Hi Alloy,
Thanks for the info, mine is a 5 speed so dont think the auto gearbox would be a problem for me. apparently fuel trap seems good will look at the MAF? sensor

Thanks for the info guys, I have taken it to the mechanic again to get some codes. this is what came up
P0089 Pressure regulator
P1093 fuel rail pressure to low
P0093 fuel system leak detected lager leak

Fuel rail pressure system low
P0087 fuel rail system pressure low

Any thoughts on what it is that would need to be replaced?
