2005 Ford F-150 V8 Four Wheel Drive Automatic 87000 miles
My 2005 F150, 5.4L will enter a forced idle mode while I am driving. The vehicle displays three error codes, P2104 TAC - forced Idle Mode, P2111 TAC - stuck closed, P2111 TAC - stuck open. I have replaced the throttle body and Throttle Position Sensor. The Accelerator Pedal Position sensor seems to be working fine. I've also had the computer refashed after all this. Still same issues and codes.
I have come to the conclusion that the PCM is bad. I located another PCM and it will be delivered today.
Can someone post the steps for switching out the PCM? Will my ignition key have to be reporgrammed afterwards?
have the same problem?
