I have a 2006 Mustang GT, this morning the car would not start. Threw code P2105-Throttle Actuator Control, the dashboard Gage shows-Check Charging System, battery has 12.8 volts. Any body out there that dealt with this code before that can help me out with resolving the problem. Thank you.

P2105 is an informational code that usually wants you to look for other codes. If i remember correctly there are a few items that can cause a P2105 code but without having the other codes we cant help you.

There are no additional codes other than "check charging system". Battery is 100% charged. Boss 007 stated in one of his reply's that the alternator was usually the culprit for the codes! Boss are you out there...

The one on the right side is the motor, the one on the left side is the tps. So right.

well won't that depend on your viewing angle..... :)

however, the motor is pretty obvious IMO, it's the driver side

Point taken, I actually thought about that after I wrote that but I was too lazy to edit my post lol.

Hey bambam 06,
What was your process you used to find this failed part?
Thanks for posting the part#!


Tracing&checking all wiring, fuse box inside the passenger compartment and the engine bay till i found it. Remember that diode only goes in one way (number 1 on top faces towards the windshield)
