Code P2106 Ford Description

The electronic Throttle Actuator Control (TAC) is a DC motor controlled by the Powertrain Control Module (PCM). There are 2 designs for the TAC, parallel and inline. The parallel design has the motor under the bore parallel to the plate shaft. The motor housing is integrated into the main housing. The inline design has a separate motor housing. An internal spring is used in both designs to return the throttle plate to a default position. The default position is typically a throttle angle of 7 to 8 degrees from the hard stop angle. The closed throttle plate hard stop prevents the throttle from binding in the bore. This hard stop setting is not adjustable and is set to result in less airflow than the minimum engine airflow required at idle. The P2106 code is set when the TAC system is in the Failure Mode Effects Management (FMEM) mode of forced limited power. The P2106 indicates the FMEM action is in effect due to a concern in an Electronic Throttle Control (ETC) related component or module

  • I have a ford 500 the codes are p0701,p0403, & p2106 what are the and is it major work?

  • What year is your Ford Five Hundred? You may have to replace the throttle body. Here is a video that shows how to replace the throttle body:

  • I have a 2006 Crown Vic Police Interceptor, And code P2106 keeps popping up and putting my car limp-mode (but 14 out of 15 times during winter). I have not replaced a throttle body or any other part yet. Is there any other items or issues that may cause this?

  • Any other codes or symptoms? Other than the throttle body I don't see any other component that could cause that code.

  • I have a 04 Ford Explorer 4.6 liter in the engine failsafe light came on and I put it on a code reader and the code popped up p2106 and p0103 what should I do

  • The codes are for different problems. The P2106 is for the throttle body and the P0103 is for the Mass Air Flow (MAF) sensor. Start by cleaning the throttle body and MAF and clearing the code.

  • 2004 Ford F150 4.6 fault codes p2106 p2196 p2198.what code should i focus on?

  • O2 sensors?

  • Looks like both sensors are reading the mixture too rich, which is unusual that both sensor reading the same, this could be caused by advance timing. If you haven't done anything the the timing, then its possible that the "Variable Camshaft Timing" is causing the problem. Start by inspecting the Variable Camshaft Timing Solenoid.

  • I did have a superchips chip in it for more towin torque never had a problem until now

  • The chips add the extra torque by advancing the timing. Either the chip failed to retard the timing, or the O2 failed due to the extra gas during the time advance. Try disconnecting the chip first, but if that doesn't work, may have to replace both O2 sensors.

  • I took it out and no change im thinking thats what killed them plus they have 99k on them

  • 2006 expedition. P2106 and p0305. Could the cylnder jumping off the P2106?

  • I'm sorry, not sure what is your question.

  • Sorry, Im getting a code of P2106. I have a 2006 expedition. Should I replace the whole throttle or could it be censors?

  • You could try cleaning the throttle body and clearing the code first. If the problem comes back, you would have to replace the throttle body.

  • Thanks!

  • 06 Lincoln town car 60K miles code P2107 - we have changed TBI unit twice, still get code! Please help

  • 2004 F150 4.6l V8. Code p2106 and no other codes after a FMEM event. No other failure lights.

    Intermittent driveability issues similar to a miss or transmission problems most noticeable first thing in the morning. New plugs and new TB still same driveability issues.

  • Have you watched the video above? sounds like you have the same problem.

  • Watched the video which was good but the lack of other warning lights and codes is what bugs me the most and the complete lack of repeatability of the discrepancy.

  • OBDIITech, I'm getting P061B and P2106 error codes on my 2005 Ford Five Hundred. Frequently, when I start the car I see a wrench symbol, and in that condition the car is very sluggish. It goes away if I turn the car off and restart. Then things seem fine. Any thoughts?

  • Start by checking the air filter, change the filter if necessary. If the problem persist, then the next step is to clean the Throttle Body. If after cleaning the throttle body you still get the codes, then you may have to reprogram the PCM or replace the throttle body. Most of the times, when both codes are present the problem is the throttle body, but try cleaning the throttle body first.

    Here is a good video on how to clean the throttle body. I would recommend disconnecting the car battery and throttle body, before cleaning.

  • Same car as above, multiple codes.
    2006 Crown Vic Police car (P71). Yellow wrench and engine does not run well. Codes: P2106, P0505 (IAC Circuit fault), P0102 (MAF sensor circuit low input). Any advice where to start?

  • There is a factory service bulletin for a similar problem:

    Some 2005 to 2008 Crown Victoria Police Interceptor vehicles built before 10/19/2007 may exhibit MIL illumination accompanied with a lack of power and/or a buck/jerk condition on acceleration, especially in colder temperatures. This may be caused by an improperly sealed air box resulting in inaccurate air flow measurements by the mass air flow (MAF) meter.

    ACTION
    Check lower air cleaner assembly for case distortion resulting in improper air filter positioning. Follow the Service Procedure steps to replace the warped air cleaner assembly.

    NOTE: THIS ONLY APPLIES TO CROWN VICTORIA POLICE INTERCEPTOR VEHICLES.

    SERVICE PROCEDURE
    1. Remove the upper air box cover. Check the lower case for outward distortion of the walls which results in improper air filter fit. Check any areas along the length or width of the air filter seal which are not in contact with the lower case.
    a. If the case is not warped, do not continue with this TSB and refer to the Powertrain Controls/Emissions Diagnosis (PC/ED) for further diagnosis.
    b. If the case is warped, proceed to Step 2.

    2. Replace the air box assembly.

    3. Clear all DTCs.

    I hope this helps. If the air box cover is OK, then you probably have a problem with the Throttle Body
