Any idea? Fuel rail pressure sensor? Fuel pump?

we have had pumps and sensors condemned on rough running/nonstarts,only to find fuel filters blocked ,got to be first step ?

I am thinking the same since I haven't replace the fuel filter for 180,000 kms yet, but when I read the manual on how fuel filter replacement is done, it's insane as you need to dismantle the fuel tank as well!

is that pressure on idle?that looks about right if it is.

180000km??? I think your filter is well and truly blocked,and its under the bonnet not in the tank,what manual says in the tank?

The (variable) fuel pressure on 3.2L gasoline engine is created by the fuel pump which is driven by the ECU through an PWM signal. Therefore there is no return line or other devices to regulate the fuel pressure.
You may have a fuel pump which is on its way out... Or maybe you are lucky and it is only a bad electrical connection. After such mileage, who knows...

Fuel pressure information from manual said

for i6 3.2 L petrol engine

Fuel pressure - fuel rail - normal operating condition not using IDS is 3.7 bar = 54 psi



Fuel pressure - fuel rail - normal operating condition using IDS is 4.8 bar = 68 psi

Fuel pressure - fuel rail - engine off using IDS is 2.8 to 3.2 bar = 40 to 46 psi

Fuel pressure - fuel rail - cold start using IDS is 6.5 bar = 94 psi

SO I assume that fuel rail pressure is correct that 372 kPa. CMIIW

Yes, is correct, but the error may appear occasionally...
It would have been nice to have the sub-error code and the status bits for that error...

Seems this iCarSoft doesn't support the sub-error code of LRs

Dear Friend, it was also common in my FL2 SD4, whenever he thought of reaching the quickdown was immediate engine power reduction, many spoke in air intake for turbine hose, but it came down to simple fuel filter exchange LR007373 (except error). Big hug!

ON LR2 HSE i6 petrol, fuel filter comes with fuel pump, so change fuel filter means you have to replace whole fuel filter and pump its not cheap both part and installation job, since you must remove the tank

Did you end up getting this fixed, adywicaksono? I also had an '08 LR2 with the 3.2 i6. Had the same error code as well, I believe. 160,000kms on mine.

So far, a simple replacement of the fuel flow sensor has fixed the issue. Easy to access in the engine bay, Alex Pescaru indicated it to me although I ended up getting it done by the dealer). The engine would stall sometimes in hot weather after long trips, and the error code you mention showed up.

Hope this helps

Cheers
