I checked my codes and it says (P2106 THROTTLE ACTUATOR CONTROL SYSTEM - FORCED LIMITED POWER)

I dont know whats wrong. i think i might have done something when i cleaned my throttle body.

Any info on this is greatly appreciated

Thanks!

2005 f150 5.4

 

Your truck has electronic throttle control.
If you took the drive assembly apart, you got something messed up.
Why are we cleaning this on such a new truck without a a DTC code as a reason to do so?

 

I think he was advised to do so

 

Truck started stalling from all the build up in there. not great air flow

 

P2106 is an informational DTC. It's set when the PCM sees something is wrong; it doesn't know what to do, so it defaults to a known good operating pattern (in this case, forced idle/no power so it doesn't stick wide open, sending you careening into trees, other cars, or off a cliff) until it's fixed.

You'll very rarely, if ever, see P2106 alone, there's should be another DTC in there - usually something like P2110, 2111, 2101, and a few others that'll get you a better idea of what went wrong to cause the PCM to go into reduced power mode. If you're using a built in scan tool that comes with a tuner, you may not be able to retrieve all DTCs.
