ANyone know anything about this and how to fix it?
I am guessing it has something to do with the ign switch cause everytime i go to turn the car off it turns off... kinda turns back on then completely off.. like it hesitated to turn off..''

Anyone had this problem before.

Oh and i am a trifecta dealer so i read the code and it says something like: Driver 5 SES line 2??

Sounds like you indeed may need a new ignition Switch.I dont think it the pcm though from the way you explained the code is coming up.

The Throttle Actuator Control (TAC) System determines the drivers intent and then calculates the appropriate throttle response. The TAC system achieves throttle positioning by providing a pulse width modulated voltage to the TAC motor. The powertrain control module (PCM) is the control center for the TAC system. Ignition 1 voltage is supplied on 2 separate circuits to the PCM. If the PCM detects a voltage difference between the 2 circuits, DTC P1682 sets.

Observe the Freeze Frame/Failure Records for this DTC.
Turn OFF the ignition for 30 seconds.
Turn ON the ignition, with the engine OFF for 10 seconds.
Does the DTC fail this ignition?

Go to Step 3
Go to Testing for Intermittent Conditions and Poor Connections

3
With a test lamp connected to ground, probe both sides of the 15-amp ECM/ETC fuse.

Does the test lamp illuminate on both sides of the fuse?
--
Go to Step 5
Go to Step 4

4
Does the test lamp illuminate on one side of the fuse?
--
Go to Step 6
Go to Powertrain Relay Diagnosis

5
Turn OFF the ignition.
Disconnect the powertrain control module (PCM).
Test the ignition 1 voltage circuit that is supplied by the ECM/ETC fuse for an open or for a high resistance. Refer to Circuit Testing and Wiring Repairs .
Did you find and correct the condition?
--
Go to Step 9
Go to Step 7

6
Turn OFF the ignition.
Disconnect the PCM.
Test the ECM/ETC ignition 1 voltage circuit for a short to ground. Refer to Circuit Testing and Wiring Repairs .
Replace the fuse if necessary.
Did you find and correct the condition?

Go to Step 9
Go to Step 7

7
Test for an intermittent and for a poor connection at the PCM. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs .

Did you find and correct the condition?
--
Go to Step 9
Go to Step 8

8
Replace the PCM. Refer to Control Module References for replacement, setup, and programming.

Did you complete the replacement?

9
Clear the DTCs with a scan tool.
Turn OFF the ignition for 30 seconds.
Start the engine.
Operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that you observed from the Freeze/Frame Failure Records.
Did the DTC fail this ignition?

Ok so this is telling me to test the connections?
Funny thing about it is if i clear the code before i turn off the car it doesnt do the sputter off and on thing..
