Hello, I"m having a little problem with my recently installed Roush supercharger. Truck ran great two days ago. Won't start with supercharger installed and it's now showing codes P2101 and P 2107. These codes pertain to TAC module, but there wasn't a problem with them till the supercharger was installed. Was thinking PCM problem from roush. Any advice would be appreciated.

dying to get this thing running!!!

this is all i could find with a quick search. but what is odd is why it would do it after it ran ok for two days?

P2107 - Throttle Actuator Control (TAC) Module Processor Description: The electronic throttle control (ETC) area of the powertrain control module (PCM) failed the self-test. The concern could be the result of an incorrect throttle position (TP) command, or TAC motor wires shorted together. Possible Causes:

• TAC motor wire shorted together
• TAC motor circuit wires shorted to PWR
• Damaged electronic throttle body (ETB)
• Damaged PCM

Thx for replying. When I stated that the truck ran two days ago I was referring to the period of time before i disassembled and installed the supercharger.

oh oh ok. hmm lemme make some phone calls and see what i can find out. i mean theres not too much to that install, so it would make sense if there was a problem with the new chip that came with it

I know when I installed my Whipple part of the install is to extend the electronic throttle harness. There are 2 yellow-white wires that can easily be crossed. Perhaps this is your issue or perhaps a connection has failed. Heres an excerpt from my manual.
57. Locate your electronic throttle connector on passenger side of engine (4-pin black connector with red latch [yellow-white{1}, yellow-white{2}, pink{3}, gray{4}]). !! CAUTION !! Use two pieces of tape (or mark/stripe with black sharpie) and wrap around the yellow-white wire coming from pin 1 (there are two wires, this will help distinguish which one is which, they cannot be crossed). Install one closest to the connector, install the second piece of tape approx. 6" away from the connector.
　
58. Use the supplied wire to extend the electronic throttle wires (4-pin black connector with red latch [yellow-white{1}, yellow-white{2}, pink{3}, gray{4}]).

�� Cut the wires approx. 4" from the connector.

�� Slide the rubber connector boot off (if applicable).

�� Strip both ends of wire, slide supplied heat shrink over wire.

�� Solder the supplied corresponding color wire.

�� Once soldered, install heat shrink over wire and apply a heat source (heat gun) for proper wire sealing.

Thx for the help. We did extend the TPS sensor even though it wasn't part of the instruction. To keep form doing what you suggested might have happened, we cut and spliced 1 wire at a time.

Thats great. You were smart about it. I would however go back and check the integrity of those connections if you haven't already.

Well, Roush is convinced that it is a PCM problem with their programming. Shipped it back to day. Back wednesday. Got my fingers crossed.

Truck is dead ATM and been that way for a week

That sucks. But at least your making some headway. So what kit did you get?

Well...I was originally looking at the Magna charger w/8 lbs of boost and was going to put a 10 lb pully on it during the install. Magna quit making them and doesn't know when and if they are ever going to again. But took em 3 weeks of stringing me along for them to finally tell me that. Then I found this kit on Roush. Same kit they put on their factory stuff..6 lbs I think. The cost of the kit was half of what the 8 lb package was, and I decided to use the left over to put leather in the truck. So..with the leather done in a nice two-tone grey and black and the rims and wheels and true duals on it now, it will finally be complete when the programmer gets back and it actually fires up.

Decided against the 10lb boost due to engine wear and tear. Even though the inards are forged from the factory, I wanted to keep this thing around for 5 yrs min. And with all the addons, I plan on driving the heck out of it now. Mostly use it to tow my boat and back and forth to work. That will change.
