Default p2135 code

The car has been going into reduced power mode and this is the code that came up. Throttle/pedal position sensor/swithch voltage correlation. It's happened three times. If I turn the car off and wait two minutes It drives fine but the engine light is still on. Any thoughts? 07 ls2 Maggie stock throttle body. thanks

Triple check all your grounds: Engine to body, battery to engine, battery to body. I had a problem with my SS Silverado going into REP mode and it was a ground that was a quarter turn loose.
