I forgot to mention I have a safc2.
I'll look it up to. Do you have any idea on my problem? also how would I go about testing the wires to the sensor? It seems like every post I find on here your a very big help to them! Thanks.

Heh, don't tell my wife I'm on here.... I've been trying to spend less time volunteering on forums these days.
The SAFCII may account for a code 31 (and possibly the code 24 depending on how it's wired.... I can't recall if it intercepts the intake temp sensor wiring or not) without anything actually being broken. It (like other more complex piggy backs) has a small initialization period during which it interrupts the AFM's KS (and possibly THA) signal(s). Under this circumstance the error codes won't affect performance, they were recorded and the event ended right after the engine was started. **Actually, the SAFC II doesn't intercept the IAT so it's out as a likely cause for the code 24.
Well, unless you're using the wrong settings on your multi meter, the IAT portion is broken (the E2 and THA pins). Did you try measuring your friend's AFM per the manual so you know what to expect from a good meter?
Who installed and setup the SAFC II? Are you confident it is properly set up? Unless you're running some significant mods the fuel trims shouldn't be too far from zero in the fuel tables. Check your system settings against those in the writeup here:
http://mkiiisupra.net/bbs/showthread...ght=guide+safc As long as you're not running large injectors on the stock AFM or other mods such as increased fuel pressure you can also try unplugging the SAFC II and reconnecting the two ends of the KS wire (should be the only one that was actually CUT) to eliminate it as a suspect... I recommend doing so if possible and while you're at it thoroughly inspect the wiring harness where it's been altered/tapped.
Is this a new problem? If so what has been worked on recently? Codes 31 and 24 are the only diagnostic codes you're getting?
