Question about 2005 Ford F-150
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
Part are avail from Rock Auto.Com

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.
