P2104 - Throttle Actuator Control System - Forced Idle

This code is for a faulty throttle position sensor check to make sure your TB (Throttle Body) is not stuck. 2104 = ECM could also be faulty.

Its possible that you have a bad Throtle Actuator and bad Throtle Pos Sensor (according to the Ford dealer) they need be replaced .

Hope helps.

SOURCE: car goes into failsafe mode; codes p2110 and p2107

Bad ignition coil,spiking the PCM,spike comes back on TPS Sensor,then to PCM again,putting the car into ETC Failsafe,and you can only go 6 MPH.

If the coils are not the issue,then the 2110 & 2107 come into play, and you spend $700,00 just for a new throttle body. The motor in it is not replaceable as of 2010,may be some day
In that case you better put it on yourself. Only (4) 10mm bolts,but you have to drain a little coolant,as it goes thru the throttle housing

Reading codes


Check the wiring to the throttle body, check the supply voltages as well. Check fuses too, it sounds like it received a voltage spike and then lost voltage and is now forcing limited rpm.

I got codes P 2104 & P 2112 - what is this and how can it be sloved?


P2104 - Throttle Actuator Control (TAC) System - Forced Idle
P2112 - Throttle Actuator Control (TAC) System - Stuck Closed.
P2104 was set because the pcm had to step in to set the idle. The TAC system is in the failure mode effects management (FMEM) mode of forced idle. P2104 is just an informative code, set because of P2112. P2112 possible causes: Binding throttle body, stuck closed or
Damaged PCM

tell your dealer technician to follow pinpoint test DV1 in the workshop manual. (but also to reference test QE1) DV1 deals with him/her checking the throttle position voltages, if these voltages are not within spec, proceeding with checking for obstructions in the throttle body, then if this passes, he/she checks the wiring to the TAC assembly. there are many steps in this test and since the truck isnt here i can't tell you where the test will go (throttle body assembly, PCM, etc.) most likely it will be the throttle position sensor which is a part of the throttle body assembly or a simple connector coming unplugged or wiring being cut, but once again since i dont have the truck in front of me i can't be 100% sure. good luck. hope this helps.

DTC P2104 - Forced Idle Mode


In this mode, the throttle plate is limited to idle speed and limited vehicle speed (about 30mph) only. This can be caused by 2 or more APPS sensor failures or a stuck throttle related DTC.


The above was from the following link:
