well I got a list of codes from the computer today when i scanned it. there are 5 codes, one for the fan and the o2 sensor (bank 1) i know about, the other 3 i have very little idea.

Code #113 ACT(AIR CHARGE TEMP SENSOR?)/ IAT (?)/ VAT (?) circut above max voltage -40 F indicated

Code #124 TPS/Pedal position higher than expected ( I had replaced the throttle position sensor a few years ago so im not sure if maybe the other code is setting this one off or not, any opinions?)

then i did a KOER test and got

Code #412 Cannot control rpm during self-test high rpm check.

Any ideas or if anyone had these before what could they be?

is your check engine light on? that sensor is on return plenum near the vac boost nipple by brks if its dirty you can get that code try cleaning it and sensor plug it may be dirty conection or bad sensor they are cheap i got one fromauto zone for $14

412 is caused by vac leak or bad IAC
