try using the scan tool to reset the ECM program
code p 2104 refers to throttle actuator control(TAC) system---forced idle mode ===causes ---wiring--TAC motor ---APP ensor--ECM
code p 2112 refers to throttle control actuatorTAC system---actuator stuck closed ===causes ---throttle body, throttle valve tight/ sticking
or TAC system--circuit malfunction===causes wiring short to positive ---short to ground ---throttle position sensor--- ECM

Correct code P0504?


What Colorado do you have ? 2 wheel or 4 wheel drive ? Sport ,sport LS 3.5L , Z71, Z71 LS. etc. what size engine ? an does it have electronic throttle control ? I have factory service info an it is not showing that code .
DTC P0506

Circuit Description

The throttle actuator control (TAC) motor is controlled by the powertrain control module (PCM). The DC motor located in the throttle body drives the throttle plate. In order to decrease idle speed, the PCM commands the throttle closed reducing air flow into the engine and the idle speed decreases. In order to increase idle speed, the PCM commands the throttle plate open allowing more air to pass the throttle plate. If the actual idle RPM does not match the desired idle RPM within a calibrated time, this DTC sets.

DTC Descriptor

This diagnostic procedure supports the following DTC:
DTC P0506 Idle Speed Low
DTC P0507

P2106


It is NOT a failed Throttle Body

FORGET the 2100 ford codes

The problem is bad cop ignition coils

Change the spark plugs
Change any failed coils or all of them
Change the Front Oxygen Sensors at 100,000 miles
Clean MAF Sensor

Clean throttle body --- CRC- throttle body cleaner-instructions
on back of can

In a very very very rare case the TACM Motor may fail
on the throttle body & you have one of the also rare vehicles
that you can actually buy a new motor for, without getting a
$600 throttle body
Those motors Dorman has & Amazon I believe for $75.00

NO reason at all that YOU can not do ALL that work yourself

Emissions light is on 2005 Ford Expedtion


Thanks for the inquiry,
I did some research and found that this error usually generates codes that both source back to the electronic throttle control on your engine. Go down to one of the major auto parts stores and they will check the codes for you usually at not charge.

Most common: [P2104-Throttle actuator control system-Forced Idle] [P2112-Throttle actuator control system-Stuck Closed]
Having not examined the vehicle, I'd suggest two things for you:
First- replace the controller, which is attaced to the throttle body with one from a salvage yard.
secondly- get some old rags and clean inside the throttle body using carb cleaner.

With luck, this should clear up your problem.

Best regards,
TF

Trouble code p2104 & p2112 for 2005 ford explorer xlt


There is a motor on the throttle body that opens it

It is called a Throttle Actuator Control Motor (TACM)

Those are the codes you got

DO NOT replace the throttle body

Spray the throttle plate with- CRC Throttle Body Cleaner

You should also have COP Ignition Coil-- Codes

A bad coil may be spiking the PCM,coming back
on the TPS and setting thoses codes

2005 Explorer changed EGR valve due to code and now fail safe mode is in and wrench light is on. Vehicle starts but throttle does not work.


Most likely the ETC Fail Safe (Electronic Throttle Control)
Various Codes for the Throttle Body will be present

Before you replace the Throttle Body because of a failed
TACM (Throttle Actuator Control Motor) Spray the throttle
inlet and plate with CRC Throttle Body Cleaner

The Failsafe can also occur from a really bad COP Ignition
Coil spiking the PCM (computer) and coming back on both
sides of the TPS Sensor. You then loose throttle plate
position and thus shut down or go only 6 mph

Im trying to locate the throttle actuator control unit on my audi a3 as i have a engine managment light on

The electronic throttle acuator is part of the throttle body. Just follow the air inlet tube from the air filter box to the throttle body where the throttle pedal cable attaches.

2005 Ford Expedition (4wd) with trouble codes p2104 and p2112 completely cuts off at low speeds. All signs point to throttle position sensor, but want to make sure I'm on the right track.


Shown here is the P2104 obd2 code and their general meaning. For a brief description of any particular OBD2 code and how to fix the obd2 trouble code, please browsw below. P2104 Engine TP Actuator Cntl System
This obd2 code is very common on newer vehicles which contain new design of throttle positioner sensor. Instead of putting a tps sensor at the side of your throttle body as in older engines, a throttle actuator control system is installed which eliminates the mechanical linkage (cable) between the throttle body and the throttle pedal. Under the throttle pedal, a throttle switch is installed and a throttle module or actuator is incorporated beside the throttle body. Because there is no mechanical device that wears out, it is more effecient in delivering better mileage and performance torque (besides...the actuator module performs better in getting all throttle signals to the ecm and trany).
To test this code, check the integrity of the wires going to both the throttle body actuator and the ecm including the throttle switch. Most of the time, if you have symptoms like trany going to a limp mode, the culprit originates from the trany circuit. However, if the symptom is engine related like hesitation, the problem resides in the throttle actuator itself which may sometimes includes the replacement of the whole throttle body assembly. Contact ATS if you need a wiring diagram or detailed fixes for your throttle actuator control system.
TIP:
Before replacing the throttle control actuator and throttle body, try cleaning the throttle plates and all plug-in wiring connections. Also, watch out the throttle body mounting bolts which can easily break (use care) when removing them.
