Hello, what is the year make and model of this vehicle?
Customer: replied 11 months ago.
2005 towncar with a 4.6L

Thank you for the info. The P2106 means the throttle body is in forced power mode. This is due to a defective throttle body. Some people claim cleaning the throttle body will correct it. The correct repair from Ford is to replace it. The P0715 is for the turbine speed sensor on the transmission. When it fails it can cause hard downshifts. It is mounted to the outside of the transmission just above the manual lever that shifts the transmission into gear. If you have hard downshifts the sensor it bad. If the downshifts are ok I would replace the throttle body and retest.

Yes but can a speed sensor also give you that code or an EGR module give you aTAC System Forced Limited Power ? Because the Actuator has already been replaced
Expert:  James replied 11 months ago.
The speed sensor I haven't seen it set a throttle body code before. Anything is possible though. If you didn't use a Ford throttle body it could be bad also. Dorman parts have a high defect rate when used. I would replace the speed sensor first and retest.

Yes it was a Ford product
Expert:  James replied 11 months ago.
Ok so I would replace the speed sensor. Clear the codes and keep alive memory and retest
