i got the above code 43 with my mil light on its driving me mad ive not a clue what it is....now i wanted to check the tps but i dont know what terminals to check the resistance on so that buggered that same with the idle control valve which ill clean and set up again along with resetting the ecu...has anyone else had this problem and did u fix it?

 

double check the code mate 43 isnt on the fault code list...

42 is idle switch
44 is wastegate control solenoid valve

think u will find the first flash is just to let u know its starting, your fault code is maybe 33 which is vehicle speed sensor 2

hope this helps

use the link get yourself the workshop manual for 93-96 imprezas gives u everything ul ever need to know

 

ive triple checked it mate its driving me mad

 

Accelerator Pedal Switch. Do you have a chipped ECU by any chance?

 

theres a chance of it mate im sure why?

 

lift the carpet on passenger floor and check ur ecu, if it has been changed from standard you will know as you cant remap the standard one..

 

i was always told that the earlyer ones u could remap but the later ones from 98 on u couldnt?

 

na man ive got a 96 myself 4 plug ecu cant be remapped

 

The MY93-96's can be remapped by ESL Live, thus keeping all the OEM ECU sensors/features/diagnostics, etc.

The MY97/98 need Apexi or Simtek (or other aftermarket ECU).


Stompers, I take it, by your question, that you have a pre-Sep 96 "phase 1" MY96 (small slanty iC and individual coilpacks-on-plugs)? If so, then it is mappable as mentioned above, so you still could have OEM diagnostics - whether it's an untouched std ECU or mapped by ESL. If you have a std OEM ECU case, you'll have to take the lid off to double-check what's actually inside.

All that said though, if you were defo getting the long and short flashes after doing the code read procedure, I can't see it being an aftermarket ECU that you have!

I'd recheck for the codes again - you may have misread it as 43 (e.g. might have been 42 or 44 or something...)

 

Wrong - see above ^^^.

It can't be remapped as is - but the addition of an ESL Live daughterbard does make it remappable, and still behaves as OEM i.e. with all the Subaru sensors/diagnostics untouched...

It's the specific "phase 1.5" MY97/98 3-plug ECUs which, so far, you can't remap by ESL Live, as it's not yet available (although they've been working on it since, seemingly, time itself began!... )

 

hmmm now im sure it was 43 but now ive changed the throttle body as the old was was stiff as boots n done a reset ive now got a 42 idle control valve so ive reset the ecu and adjusted the idle speed to what it should be now ive found out how and the light is off so will have to wait n see what happens for now....as for the ecu im guesing its more than likly standered tbh

 

Chances are it was indeed 42 (not 43) when you first checked.

I agree that you prob have a std ECU.

 

Ha. I took it as read that skinneyman's statement of code 43 is not in the list... But see here:-

Subaru Specific Trouble Code Definitions

...It's very much on the list - it's the accelerator pedal switch!

 

there is that chance that i was a total numpty n misread the flash's everytime? tbh i wouldnt put it past my self aha but just come back from a run into town and no lights as yet maybe the light came on from it not being set up right?

 

If you have a chipped ECU code 43 can be ignored. Its due to the map. I started a thread about it somewhere, as i had a code 43, due to my PP chip. Just ignore it.

Post 29!

 

i dont think this list is all included by the onboard system through ecl, dont quote me on it but as far as i was aware ther was only a small list of codes that will show on it, is this list maybe relating to a select monitor for as many codes??

 

Possibly(?).
