Hi folks

Changed lambda sensor today as ecu was throwing the code up, after fitting I did another reset, the lambda code has now gone but another code has come up. the code is 43 ? Does anybody know what is this as its not on the impreza list ?

Thanks White-un

 

sorry to hijak how do u do the ecu test ? or are u using a machine?

cheers

ona list i have it shows accelarator peddle switch . on the re set did you press full throttle for 5 secs then half way for 5 secs then let off then start car as i was led to belive this was the way.

 

I followed this to do a reset JollyGreenMonster.co.uk

Should I do it again and hold throttle for longer ?

 

as JGM states just full throttle then half way for 2 secs so this will be right. maybe you could try longer see if it helps ive always left it longer and if ive had a cell code like speed sensor or something to do with car motion ive just drove it and they have disapeerd. hope it clears

 

I'll try again and hold it for longer, see if clears it.

thanks White-un

 

no its still coming up with error code 43 ? can anybody help ?

 

another way would be to take battery off for a good few hours to re set it.
this might sound like a long shot but if the accel switch is near the peddle you might of disturbed the wiring conecting it due to pluging black green plugs in and out and its all in the same place it could be worth a cheak.........

 

43 is Accelerator Pedal Switch and i have no idea why it is being registered

 

is it faulty ya think ? I have a ESL board on the ECU would that make any difference ?

 

dont know about that some1 will. but as i said above cheak the wiring it dont cost ewt to look and could of been knocked when pluging in reset connectors

 

Check all wiring, looks fine under there, I've done a reset a while back so the plugs were easy to get to, didn't disturb anythin under there ???

Anybody else got any ideas ??

 

Is it UK car if so then 43 is a red herring and nothing to worry about. Just ignore it.

The base code in the ESL ECU is from a Z4 ECU WRX where the code is valid.

The Prodrive UK ECU upgrade does the same, as it too uses the Z4 Code.

 

Yeah its a UK, thank **** for that ! I thought there was another problem to sort ! Thanks Scott
