View The Full Version : Temporary error, fuel pressure Punto 1.3 Mjet 70CV
Hi, I have another small problem that I jump out with the map of my point that I don't know if it depends on rail pressure too high or a real failure of the power supply.
We say that ? a fact only the visual as it turns on, sometimes the light on the ecu but the machine continues to work properly without going into recovery.
With *********** I have the following error:
P1196 - Error a temporary fuel pressure
The Fuel System Pressure is outside the normal range. Check the pressure regulator for being stuck, and the pressure sensor for correct readings.
Make sure that the filters are clean and that the fuel feed and return pipes are not blocked.
Verify also that there in enough of the proper quality fuel in the tank, especially in cold weather conditions, when summer grade diesel may build paraffin crystals and block the filters
The cause of this error ? that the ECU has received an extremely high signal from the sensor. Error not present, but kept in memory.
...
As the rail pressure are 1470/1480... pu? depend on this? it seems to me that it has lower pressures not to do so. But I don't know if it is too much pressure in the rail or the lack of diesel due to the bigger request when I have the pressure pi? high.
Could depend on the map,e-mail l ori and mod that let's have a look
After step to take the laptop with the files, there are maps that I was doing the tests in advance, and the rail taking a cue from a 1.3 opel 70 hp... and injection times are quite high..
However, I noticed that it does it in first gear if you exceed the 4500/4600 rpm. If I pull the less the gear does not'...
the pressure ? in the parameters if the car continues to walk, adjust I think it is a problem of the map

hello,according to me, the rail pressure and high...mail ori and mod!!
You with maps, pi? conservative not by error.
Here is ori and mod

here's what it says in the post in English:The fuel System pressure ? outside the range of normality?. Check the pressure regulator that is not locked, and the pressure sensor that gives correct readings.
Make sure that the filters are clean and that of the fuel supply and return are not blocked.
Also, verify that there is enough fuel quality? adequate in the tank, especially in cold weather,the diesel grade summer winter pu? build crystals of paraffin wax and block the filters.
Have you tried to ensure that all recommended to be in place??
But tap control half the machine :)
1. check the pressure regulator that is not locked.... where and how you can? check?
2. the pressure sensor gives correct readings..... how to check?
3. make sure that the filters are clean and that the power supply and the back are not blocked...... here I could replace the filter and make sure I do not know in any way the pipes
4. verify that there is enough fuel..... well here it is, even with the full.
I had the idea that this error is because? in view of the high demand of diesel fuel in any given situation is that the feed pump is not able to provide input to the pump of the rail that particular pressure. In the corner? words that cannot stand behind the demand of diesel high-pressure pump.
Let's say that if the problem occurred with the original machine this lack of power may be derived exactly from the filter or ducts clogged or just diesel and cold temperatures.
Pu? be cos?? I seemed to have read once that on the jtd 105 modifying a valve that was on the diesel fuel filter by putting one with higher pressure so the food better, the pump of the rail... of course with maps thrusts.

I looked at your map and I think you touched on too many things in an exaggerated fashion,on this type of ecu less touches and better',do not forget that the graphics using the titanium to describe the maps are not always correct above all these,in a few words you have given too much diesel in the wrong places, and this is not good.
Review the map and edit the graphics using the titanium:
iniez prov 1 too much diesel and given evil
iniez prov 2 without the logic of increase
limit torque too much fuel because evil
ditto
ditto
One thing that I can not understand, in fact, that if I type in the fifth low-speed and I press all the car does not smoke, as if shot 1-2-3-4-5 smokes a lot....
Doing a log with EDF's possible that I have a ratio of air to fuel of 20?

Injections zoned 1 as he calls ecm and otherwise to the address 068A44 I also studied with winols, where I did an mappack correct and still are the times of injection as a function of the rail pressure and from IQ in mg/stk, the increases are high but I don't understand where you mean evil.
Injection zoned (map 1) and in any case 0675BE ? the pressure of the rail as a function of engine speed and IQ in mg/stk, and even here it seems to me quite correct the interpretation.
Torque limiter 06479E ? the map of pedal, it increases higher, you here as you comply?
Torque limiter #2 064A02 ? the torque limiter as a function of the temperature of the water and the engine revs... this maybe could? be too but I don't know.
Torque limiter #3 065AC0 some say that changes nothing to change it or not...

1. check the pressure regulator that is not locked.... where and how you can? check?
the pressure regulator can safely check with a tester...
2. the pressure sensor gives correct readings..... how to check?
the pressure sensor, you can also check with a tester of the righteous voltages,usa ********for vedereche voltages shall give,or you may want to check with the FES by monitoring the pressure and objective pressure measured..the two values we should not be too much of a difference in max pressure: 100-150bar
3. make sure that the filters are clean and that the power supply and the back are not blocked...... here I could replace the filter and make sure I do not know in any way the pipes
once sostiuito the fuel filter before connecting the piping to return you to blow in with compressed air..I recommend not to overdo it..and remove the tank cap....the eye that if the sebatoio and full and puffs so you could also break it since bochettone supply I know that fit a non-return valve and being of plastic and easy to the full as a reed-pipe..for which eye...blowing "hits" short so that the air that enter at the time of discharge from valvolini vent..
4. verify that there is enough fuel..... well here it is, even with the full.

in the 1.3 multijet, you can't vary the pressure and low pressure because the control valve ? integrated in the lid of the fuel filter...
check all, and then let us know...
For me it's not ? mechanical problem, but the map! there is something, which you block with the pressure of the gas, try to put ori the pressure and see if you still have problems
