SOURCE: i hacve 04 lincoln somethime it goes 20 miles that

I have 05 LS. I had to codes a few days ago. After doing research on line, somebody, somewhere said it was coil #4. (passenger side nearest firewall). Not throttle position sensor or throttle body. I replaced #4 and tested around the neighborhood at times with RPM over 4k. Did not go into limp home mode. Ford will replace coils free if car has under 100K. I was in a hurry and purchased coil made by Borg Warner (limited lifetime warranty) for around $60.

SOURCE: P2106 Throttle Actuator Control System-Forced

On your vehicle, Diagnostic Trouble Code (DTC) P2106 is an "informational code". These type codes are usually accompanied by other codes. If this is the case, ALL of the other codes need to be addressed FIRST. If you are receiving this code without any other codes, there is a LONG list of things that need to be checked to find the cause.

There are a couple of Technical Service Bulletins (TSBs) that would apply to your truck depending on how it is equipped:

If your truck is equipped with an EGR system, TSB 05-3-1 may apply to your situation. This involves testing of your mass airflow circuits and verifying data from both the mass airflow sensor and the EGR System Module (ESM) and possibly repairing circuits with high resistance and/or replacing the ESM.

There is another TSB that may apply to your situation, however this TSB only applies if you are also receiving DTC P2135 along with DTC 2106. This one is TSB 05-14-4.

Hi, there is a post here on this issue: http://www.fordf150.net/forums/viewtopic.php?t=50060&highlight=p2104

Since you have already changed the TPS, I assume you also cleaned the throttle body? Is the throttle actuating smoothly? If not, make any repairs needed to make it smooth and easy to rotate the throttle.
If the throttle is good, then test the accelerator position sensor per the procedure below.
Please let me know if you have any questions, and thanks for using FixYa.
OperationThe APP sensor is an input to the powertrain control module (PCM) and is used to determine the torque demand. There are 3 pedal position signals in the sensor. Signal 1, APPS1, has a negative slope (increasing angle, decreasing voltage) and signals 2 and 3, APPS2 and APPS3, both have a positive slope (increasing angle, increasing voltage). During normal operation APPS1 is used as the indication of pedal position by the strategy. The 3 pedal position signals make sure the PCM receives a correct input even if 1 signal has a concern. There are 2 reference voltage circuits and 2 signal return circuits for the sensor.
Removal & Installation

  1. Disconnect the battery ground cable.
  2. Disconnect the accelerator pedal position sensor electrical connector.
  3. Remove the 3 bolts and the accelerator pedal assembly.

To install:
  1. Install the 3 bolts and the accelerator pedal assembly.
  2. Tighten the mounting bolts to 18 ft. lbs. (25 Nm).

  1. Checking the VREF voltage to the Accelerator Pedal Sensor

    Turn the ignition switch to the off position. Disconnect the Accelerator Pedal sensor connector. Measure the voltage between pin 6, 7 (ETCREF+) and 1, 3 (ETCRTN-). The voltage should read between 4-6 volts, If not repair circuits in question.
  2. Checking the Functionality of the APP sensor.

    Turn the ignition off. Disconnect the Accelerator Pedal sensor connector. Refer to Resistance Chart:

I have 3 codes from my scaner p2111 p2112 p2238


P2111 - Throttle Actuator Control System Stuck Open.
P2112 - Throttle Actuator Control System Stuck Closed.
P2238 - O2 Sensor Positive Current Control Circuit Low Bank 1 Sensor 1



For the P2111 & P2112 you will need to replace the throttle body this can be pricey since the TAC is built into it. Try cleaning it good and see what happens. This can also trigger the P2238 code if its dumping fuel.
For the P2238 check the connections on the o2 sensor or replace the upstream o2 sensor that should correct it.

My check engine light has come on for my 2006 Ford Fusion and 3 codes came up...P0010, P2104, and P2112. Any ideas what these mean?


Fuel and Air Metering and Auxiliary Emission Controls P2104 Throttle Actuator Control System - Forced Idle
P2112 Throttle Actuator Control System - Stuck Closed
If it's not the pedal, it has to be throttle body, senor or harness related.
