Is there no check engine light? Grab the ODB-II trouble code if it exists. Please tell me you are not trying to depress the pedal upon starting like you would with an older car? That will **** up it's position reading. If you did previously, just yank the negative terminal off again, let it sit for 15mins. Then do the below, again without your foot on the accelerator.
The above is likely unnecessary, but just to be sure... Now start it, and try again. Noting any DTCs.

This is all TPS related, but again, should be throwing a DTC if this is the issue:

You can use this as well to verify:

Turn the ignition key to the OFF position, then cycle the ignition key from the ON position 4 times to allow the car to "self check" the throttle body and sensors for proper operation.

RPM Guard with High Forced Idle
This mode is caused by the loss of 2 or 3 pedal position sensor inputs due to sensor, wiring, or PCM concerns. The system is unable to determine driver demand, and the throttle is controlled to a fixed high idle airflow. There is no response to the driver input. The maximum allowed RPM is a fixed value (RPM Guard). If the actual RPM exceeds this limit, spark and fuel are used to bring the RPM below the limit. The powertrain malfunction indicator (wrench) and the MIL illuminate in this mode and a DTC P2104 is set.
