Problem bravo2 1.9 jtdm not more

[freddyecu]

Hi all, I have this problem the car while he walked because of the sibtomi of hiccups then ? off and not ? game pi? ... In the diagnosis sensor and fuel pressure... If you fall off the pipes to the diesel fuel does not go into pressure, and if you turn on and turn off the picture of the pomettata in the tank seems to attack, but for 1 2 seconds and should be attached to the pi? to some of you, and happened to you ? Thank you in advance

I believe that it is stuck for 2 seconds, why? ? gi? pressure on the circuit!. but if you detach the hose from the low pressure that goes to the fuel filter out the diesel? and if you fall off the pipe from the fuel filter goes to the high pressure pump out the diesel?

[progress]

do as he said demolitionman if it were to exit the diesel is armed with a diagnosis, and see starting the engine how much pressure generates the pump HP rpm

[freddyecu]

? attached 2 seconds, even with the tubes disconnected the filter and the nafta leaves but little to the diagnosis already? I made out sensor fuel pressure is not clear

[dvdtuning]

Check in diagnosis, the actual values of the pressure of the pump starting up, should be around 300 bar or gi? l? in order to understand if the pump ? efficient.

[freddyecu]

330 bar fixed even with the starter driven

[freddyecu]

I tried on an alfa 147 with the same engine is on values below 10 bar motor motion oscillates between the pressures of 300 to 350. Bar so it could be the sensor on the flute ? Do you think it's ok the sensor on the jtd multijet ? Thank you in advance

I think it is the sensor, given that you mark something with the ignition switched on dovrebbbe scored about 4bar.

After tell us what engine mounts. Then that error code you read. Seen that ? a generic error(pressure oil) may be any pump, injectors, regulator, filter, pump premandata, etc....

In any case, you always start by checking the low pressure. Do a range test of the electric pump, see how much power it absorbs when ? pressure, and how much pressure reaches the control panel is on

Detach the plug to the fuel pressure regulator(mounted on the pump to the high pressure) and then make a diagnosis and see the values.. and then see if the pump off the same..the pump should not disconnect if you have the circuit of the low-pressure open !the machine is switched off and up to 10 bar are acceptable . in the start-up should piccare 500 and then spabilizzarsi to 320-350 bar!

error code ?

[frantik3]

could be the sensor in the low-pressure pump, if and to start with replacing the fuel filter and see if the water and me and happened on two alfa 159 the same symptom

[freddyecu]

Problem solved sensor fuel pressure to the rail, however, thanks to all your help x

that's weird! I aimed to replace the one near the pump! but not the one on the flute! you never stop to learn!
GLAD THAT YOU'VE SOLVED IT :D..

[marco1985]

sorry, but how could she be a faulty sensor on the rail if the diagnosis will read the pressure values correct?
you have also changed the fuel filters?

[freddyecu]

It was hard to 330 bar( locked)

ah ok, then yes! ;)
