Hello all. Need some help with our 2010 Ford Escape Limited 3.0l V6. Went to start it a few days ago and the throttle body made a couple of weird noises, engine started but idled really high initially before settling into an irregular idle. Had absolutely no gas pedal!! Did a bit of research and decided to replace the throttle body but that did nothing to change the symptoms. Ran the codes and it came up with P0123 and P2119. It looked like the accelerator pedal assembly might be at fault so I installed a used one from a 2012. Still no improvement and it's still throwing the same codes. It was running fine the day before!!! Any suggestions would be greatly appreciated, thank you.

Thanks for sharing these. I had watched the first one earlier and followed his instructions on resetting the ECM as well after replacing the throttle body. Unfortunately, it didn't fix the problem.
Did you put a new throttle body on it or used

P0123 FORD Meaning
The Throttle Position Sensor responds to the accelerator pedal movement. This sensor is a kind of potentiometer which transforms the throttle position into output voltage, and emits the voltage signal to the Engine Control Module. In addition, the sensor detects the opening and closing speed of the throttle valve and feeds the voltage signal to the ECM.
Idle position of the throttle valve is determined by the ECM receiving the signal from the throttle position sensor. This sensor controls engine operation such as fuel cut. On the other hand, the Wide open and closed throttle position switch, which is built into the throttle position sensor unit, is not used for engine control.

Causes
Faulty throttle position sensor
Throttle position sensor harness is open or shorted
Throttle position sensor circuit poor electrical connection

You replaced the TPS as it is integrated into the throttle body. Check the connector to make sure fully seated and very clean. Spray electrical cleaner into the connector if questionable.
Also check the wiring harness for any issues

P2119 FORD Meaning
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 P2119 code is set when the throttle plate is at a lower angle than commanded.

If you are getting this code on the new throttle body, that throttle body has issues!!!!! The hard stop is NOT supposed to be adjusted at all. Changing that hard stop usually voids a warranty

These are the causes.
Throttle Body Plate Binding
Faulty Throttle Actuator Control (TAC) Motor
Throttle Actuator Control (TAC) Motor harness is open or shorted
Throttle Actuator Control (TAC) Motor circuit poor electrical connection

Do check connectors and wiring harness

Thanks for the input and suggestions. I unplugged the PCM connectors, gave them a shot of contact cleaner, plugged them back and voila... we're back on the road! Did the same with other plugs under the hood while I was at it. Probably didn't have to replace the throttle body but that means we should be good for quite a while in that department.
