p0325 is a knock sensor code that usually results in no repair, a rough road surface could set this code. as for the p2101...that could be an issue and needs some diagnoseing to figure this one out.

p2101 means:
The commanded throttle position is compared to the actual throttle position based on accelerator pedal position and possibly other limiting factors. Both values should be within a calibrated range of each other. The powertrain control module continuously monitors the commanded and actual throttle positions. This DTC sets if the values are greater than the calibrated range.

So it could mean that there is a problem with the throttle body itself, the wiring, or the PCM...

Does the car have any problems while driving, or is the light just on ?
let me know and we'll take it from there.
