Hi guys i bought my 88 supra about a year ago and had major engine problems with it. Long story short, i replaced the whole engine. I am getting an error code 31. I took it into toyota and i don't think they know what they are talking about. They told me that it was cause by a bad battery. They were right about the bad battery but i still have the same issue. Any ideas?

Is 31 the AFM or the IAT? i can't remember which, if it's the IAT that can be fixed easily (had a problem with that not too long ago).

If you have a TSRM or go to the Cygnus site then run the diagnostic on it with a multimeter. If you find that you have to replace then i'd say go to the FS section and shop for an AFM.

Si tiene un TSRM o va al sitio de Cygnus, ejecute el diagnóstico con un multímetro. Si encuentra que tiene que reemplazar, entonces diría que vaya a la sección FS y compre un AFM.
