I have a Haynes manual for the Ford Probe/Mazda 626/MX-6, and it shows you how to get the ECU trouble codes by shorting pins GND and ??? with a paperclip and then connecting an Ohmmeter between STO and -VE on the battery then switch the ignition on and watch the meter sweeps.
Ever since I bought my car, (a 1994 Mazda 626 2.0 16v) I keep getting code 17 which it says in the Haynes manual is the O2 sensor (of which there is only one in the manifold), and I have replaced this and know it's working fine because the emmissions go haywire when I disconnected it, then I have to reset it.
I think that the Euro/Japanese ECU may have different fault codes to the ones in the Haynes manual (which is a USA publication) as I read on another website something about EEC-IV or something, and I found a website with fault codes for this ECU and I think 17 was "Idle speed endstop set too low" and I have a problem with my idle going too low sometimes.
So my question is, do Euro models made in Japan have the same ECU as the one in the Haynes manual and the one most of you have in North America?
Thanks.
