P0101 & p2101 help!!
Just had a weird issue happen to me yesterday on my drive home. On the freeway, the car just started to rev on its own uncontrollably. Turning the car on and off several times did not net any results. Had to pull over on the side of the freeway and had to have the car towed. Once I was able to check the codes, I got P0101 and P2101. The DIC was showing "service active handling and traction control". I checked every thread related to these codes on the forum and none seem to directly apply. The car does not seem to be safely driveable at this point. I plan to clean the MAF, but I am doubting that it will clear this issue. I cannot find any visible vacuum leaks or wires that are bad. Car has a Vararam, LS2 TB, Vararam intake duct, Vararam TB spacer, FAST 92, LG Streets, B&B Bullets, MSD coils, MSD wires.
Any help would be appreciated!!

p2101 has to do with your throttle body. If you have your stock T/B I would put it on there and then drive the car it should clear it up. P0101 is just a MAF code which should go away.
I just noticed you have a LS2 T/B I would check your connection on the adapter wire. I think I would also take the TB spacer out.

DTC P2101
CIRCUIT DESCRIPTION
The commanded throttle position, based on accelerator pedal position and possibly on other limiting factors, is compared to the actual throttle position. The 2 values should be within a calibrated range of each other. Both the powertrain control module (PCM) and the throttle actuator control (TAC) module redundantly monitor the commanded and actual throttle position. If the PCM detects an out-of-range condition between the commanded and the actual pedal position, DTC P2101 sets.

I saw that so I edited my post. I would pull the ls2 t/b off check it and clean and throw it back on there and see what happens.

Once you get the throttle codes resolved the Traction Control and Active Handling codes will go away. If the engine controls cannot perform their torque reduction function the EBCM disables TC and AH.
