You may want to check your battery. Take it to auto zone and have them do a free diagnostics test. Mine needed a new battery. (Make sure it's powerful enough too)
get your transmission modulator replaced
Disconnect the battery for a few minutes. This should clear the code. Unless you have fixed the problem that set the code it will come on again.

The 2006 Pontiac Grand Prix is not E85 compatible. The easiest way to verify off hand is to check with either a website such as http://alternativefuels.about.com/od/flexfuelsffvs/a/e85compathub.htm or to locate the VIN number (generally in the driver door or door frame, or the driver's side of the dashboard through the windshield) and identify the 8th digit of the VIN which is the engine code, and call the local Pontiac dealership's service department and provide them with that information, as well as the size of the engine, and they should be able to tell you right away exactly what fuel your vehicle can run. But again, as my knowledge goes, the 2006 Pontiac Grand Prix is not compatible. I did however notice that some of the General Motors cars were indeed compatible, so you may want to go ahead and run your information past Pontiac directly.
I Do my own oil changes on my Grand Prix GXP. I have seen many responses of for 6L. I add only 3.4.3.7L of Oil.. The Dip stick shows the oil level at the top of the hash marks (max) when the car is off. When I start the car and run it for a few minutes and shut if off. Check the oil level again level is at ( min) ..If I wait 5 minutes the level is at the max. 6L of Oil will over fill the engine and could cause damage... Does anyone know the correct level. The Kidd
My Pontiac Grand Am is stalling after it gets warm - about 15 to 20 minutes. I can let it set for 30 minutes and it will start back up until it gets hot again. I have trouble shot everything with the exception of the brain box and the IAC valve. Where is the IAC valve located? What do I need to do to change it? if this is what your car is doing, have you checked your ignition module. i had a grand prix that did the same thing. it would run for 5 to 10 miles then just die for 30 minutes till it cooled. something about how when it got hot it expanded and lost contact with the coil packs and when it cooled it contracted and you would get a good spark on the coil packs. try that and see what happens.
Clear the codes. drive the car a bit and check the codes again.
the same as the firing order set all your intake valves then go thur again and set your exh. valves.
You ask your car. If he doesnt answer, try again. Ask anything! We seriously answer your questions!
