Navara Diesel Pump

roscoe07 · Feb 23, 2015

I have been told by a D40 diesel owner whose vehicle has done 265,000 k's that i should replace the device on the diesel pump. (see picture). He says that it costs a few hundred to replace but it faulted and cost him a turbo. Does anyone know what this is called and what it does.

I am trying to get the picture up I hope this link will work.

Could be the suction control valve, they have been known to need replacing (or at least cleaning) every couple of hundred thousand ks. But I don't think it could destroy a turbo. If it's the SCV, then it's just the part that controls the fuel rail pressure.

That's the Suction Control Valve, as posted above...

Thanks for the good info. Now you mention it the engine has stopped on me a couple of times for no reason. It restarts quite easily and is fine.
What does the SCV do?
Is it better to replace or clean it - new O ring or something?

The scv or suction control valve is basically a electronic pulse driven solenoid that regulates the fuel flow into the fuel pump.the pump will pump whatever its allocated by the scv.so if you have a sticky solenoid in the scv (aparantly the internal bore gets scratched) the fuel flow gets a bit retarded.

Mine is hunting badly at cold idle and has just started random stalling when first started. And - I am pretty sure it's starving the engine from take off to about 20km/h as the engine groans and appears to labour - then takes off after that.

I feel your pain..i got a random P0093 code on the way to work this morning...currently looking at genuine denso scv alternatives....hopefully before mine croakes it

Black_Outlaw · Feb 24, 2015

I read on the Europe navara sites that the new design 'blue' tip SCV is a better design then out beige/cream coloured ones. Still expensive at 200 a pop though.

Ive found a longer one also..ill grab the link

Here is a ebay item number... 261164237333

roscoe07 · Feb 25, 2015

Thats a good link. However getting from UK means the price similar to here. Maybe someone has a Denso contact and can get the part number 294009-0120 at a reasonable price.

Like this??

Hey Camo - does that DEFINITELY FIT the Navara?

If so I am going to pull the trigger on it and grab one.. Mine is, for all intents and purposes, fully shagged.. Might as get something worthwhile if I am replacing it

Actually, if that is the correct DENSO PART NUMBER, United Fuel Injection in Perth have them..

Here's their eBay ad...
