p0105 on panda 1.2 petrol

[legendaryslave]

hello to all the forum I have a problem on a fiat panda 1.2 8v, year 2004 engine type 188a4000 injection iaw5af hybrid, practically ? arrived in the workshop with engine light on and recording the fault circuit P0105 pressure sensor collector, the first thing I did ? clean the throttle body and re-beats butterfly reset parameters self-adaptive, the machine has a seghettamento monstrous in terms of required load on the engine, after that I replaced the pressure sensor manifold+ spark plugs the car is good for a 20tina miles then starts again any ideas or suggestions
thanks in advance for any answers

Fuel Pressure?

if I remember correctly, there is a service for that problem, but for the verification of the most accurate I need the frame or plate

sucking in air somewhere!!the minimum and regular??? the tappets are ok???

I don't feel the aspirations of the fact that ? sporadic the problem and as if he went to sobs, the minimum ? adjust and when it is the fault, the tachometer goes up and down as if he stopped to give the current for a moment

Hello,try to inform you if there any update of the control unit.

Maybe you said yourself... try to check the sensor of the engine rpm. Likely when it does not read well lose the signal, as evidenced by the revolution and create the problem. Also sprinkle a little bit of spay into the plugs of the ecu, a lot of times are fake contacts to create strange problems.

thanks guys, I go on with the tests and I want to know

[carlo abarth]

but do not, and that has some mass slow???

thanks to all of the valuable advice I have now replaced the group of the butterfly, I would keep under observation

Check the two connectors of the control unit, especially the one to the brake booster (so to speak), that works too in the shot with the stresses that create the engine, generates false contacts. Personally, I got two different panda with this problem and I do not say that for the first we went to a mental hospital!!!!!!!
Ps: also check the wiring that goes to the sensor turns the part of the cable that goes in the seat of the cover of the distribution sometimes burns with all the currogato because too close to the catalyst
Hello and let us know the good work

thanks test of the butterfly failed tomorrow sost the sensor and perform the tests as described by you

Sorry I forgot to tell you: with the engine running try to move the connector and you'll see that you from the defect

thanks again you keep up to date

Check the sensor absolute pressure in the intake manifold... and the wiring... I'll give you some shortcuts, make sure there is continuity? in the cables from the sensor to arrive in the unit
Pin 1----> pin A29 control unit
Pin 2----> pin A14 ecu
Pin 3----> pin A22 unit
Pin 4----> pin A13 control unit

If you have continuity? turn on the ignition and check that the pin 3 there will be at least 5 V
On pin 2 from 0 to 0.2 V
On pin 1 of about 5 V (only for this proof to the connector unplugged)
Measure the resistance of the cable between pin 4 and A13 control unit

If you have positive feedback replace the sensor... otherwise we follow another road

the sensor is new and original continuity for granted, and that there is otherwise the error would have appeared to the key on the error appears when the machine sobbed then strattonando causes of the variations of flow in the suction line leading to the p0105

slutty babe we've taken wiring ruined when the moving jumped off the error reset the connections all ok
