q31. wrong 2 wire plug got connected to iat or iacv and, poof!. check your iat sensor (probably burnt too), and run continuity tests on the plugs to iacv and iat. more than likely pwr steering, iab, iacv was connected to the iat. i can possibly fix it depending on how bad...will have to replace the transistor you fried and jump traces. it may or may not throw a cel since the diag voltage may still be seen by the rom, but it needs to be fixed.
