P1570, P1172, P1544, P1156 Fault Codes

[jamesa13]

Hi all,

  Once again no idea whats going on with my Fabia 2003 1.4 MPi 8v.

 

codes

P1570 - ECU Dosabled - component disabled

P1172 - Throttle valve position sensor 2 - signal too low

P1544 Throttle valve position sensor 3

P1156 Intake manifold pressure sensor

 

 

Heres what I ve done before getting AA out to read and clear above codes - All because I went through a car wash and it started cutting out intermittently about 2 weeks ago - going completely mad !

 

1a.Replaced crank sensor

 

1b. Took off throttle body and cleaned it and put it back - did not do TBA

2. Unhooked ECU - No idea why i did this

3. Unhooked battery - No idea why i did this other than to reset ECU 

4. Unhooked both sensors near to throttle body to clean?

 

5. Tried to replace fuel pump with full tank of petrol and almost passed out with th fumes - puty back origfinal fuel pump - stilll hope i put it back ok - then called out AA

 

Car started after AA erased codes but went back to very bad idle and then cutting out eventually and then not starting at all.....  now back to its usual intermittent starting nonsense. Im at my utter wits end with this......does anyone have any answers ? I need a miracle or a scrap car dealer...............(((( Thanks in advance.

Hi. 

I was wondering if You got it fixed? I've got the same problem at my mother's cars. Could You tell me what caused that?

 

Thanks in advance.

Last year I had one of my cars valeted with strict instructions NOT to use a power wash in the engine bay, so guess what, they used a power wash to clean the engine !

 

Result, misfiring etc.

 

One of the multi plugs/sockets had water in causing the problem, I think I pulled the plugs/sockets apart and ran a gentle airline over them to clear any water droplets.

 

I do seem to remember that the grey coloured plug/socket on the front of the engine was one of the main culprits.

 

Hope this helps.
