I got a 04 f150 5.4 and ive ran into trouble and im not sure whats the problem. So im up in the snow right now and every time i start to go threw some thick snow my tires start to spin out and my truck shuts off on me. It only does that when i really give it some gas and my tires are spinning. Could it be the throttle body?

 

The truck has a Gryphon programmer, and is popping codes:

P0553 (P0553 Ford - Power Steering Pressure Sensor Circuit High Input)

P2105 (P2105 - Throttle Actuator Control System - Forced Engine Shutdown)

P2106 (P2106 Ford - Throttle Actuator Control System - Forced Limited Power)

 

04 could have cable throttle or electronic throttle.

1. Verify the air box is properly sealing and alsop that your air filter is not iced over, or collapsed. Also check the air inlet on the air box to make sure it is not frozen over.

2. Remove the zip tube from the throttle body, and with the key on, have someone press the gas and you watch for smooth opening and closing of the flap.

3. Clean the flap until it is spotless. I use air intake cleaner. You could use carb sleaner too.

If still getting the codes and stalling, it is time for a new throttle body.

 

Thanks, ill check it out.

 

Just thought I'd mention I have a CAI and the filter is clean.


Codes still pop up, but the truck only stalls out now when you spin the tires and rev the engine up. Don't know why.

 

I have been using my gryphon programmer and my brother's Laptop/AE to pull codes. The Gyrphon had PHP's "Custom" tune on it.

 

Only other mod is a cat-back dual exhaust with dual Flowmasters and 295/65R18 Duratracs.

 

so my brother and i took apart my whole CAI and throttle body and cleaned it. It really needed a good cleaning. My trucks no longer shutting down on me and is running much better! Thanks for the help.
