Thottle body sensor, accelerator pedal sensor, restricted air flow...will all trigger this fault light. Go to your local Autozone, they will run an OBD scan for free, and explain the fault codes to you so the correct repairs can be made.
Good luck...i hope this helps, please rate me a fixya.

P0332 Is set by a knock sensor, desiganted by GM as "Knock Sensor 2".
There could be many causes for this, from a misfire, to a loose sensor; so an appraisal from anyone without access to the vehicle is out of the question.

16716/P0332 - Knock Sensor 2 (G66): Signal Too Low

P0332 DTC Code - Knock Sensor 1 Circuit Low Input (Bank 2)
A knock sensor tells the engine computer when one or more of your engine's cylinders are "knocking", that is, exploding the air/fuel mixture in a way that delivers less power and can be damaging to the engine if prolonged.
The computer uses this information to tune the engine so that it doesn't knock. If your knock sensor on Bank #2 is generating a low output voltage (perhaps under 0.5V), then it will trigger a P0332 DTC. This P0332 code may show up intermittently or the Service Engine light may be lit constantly. Other knock sensor related DTC codes include P0325, P0326, P0327, P0328, P0329, P0330, P0331, P0333, and P0334.
You may notice drivability problems including fluctation engine RPM, a loss of power, and perhaps some hesitation. There may also be other symptoms.
Potential causes for a P0332 DTC include (but are not limited to):
The knock sensor is faulty and needs to be replaced
There is a wiring open/short/fault in the knock sensor circuit
The PCM/ECM has failed
