I have the dreaded P1091 (TGV System one stuck closed). I replaced the TGV Motor on that side (Right-or passenger-side), and unfortunately after clearing the codes and driving, it came back. I have a feeling I know why though- I replaced it in a bit of a hurry last night, and the little white half-gear inside the TGV assembly that the TGV Motor moves was at top dead center (In other words, the hemi-spherical gear was in a position such that the flat side of the hemisphere was facing down, completely parallel to the horizon, horizontally speaking). I've got a feeling that that little white half-gear should be either to one side or the other when installing the new TGV Motor- I called EFI and asked them, but unfortunately they didn't know because they've only ever really done TGV Deletes, not just a repair on it.
Question being, does anyone know to which side, or in what position, that gear should be when I install the new TGV motor? I'm really tired of being in limp mode- and can't afford a new set of TGV's, or TGV Deletes. (I did however, ask EFI to send me a copy of my tune- it was tuned using the accessport program and my accessport is dead, but I have another AP, sending them the serial number of the new one so they can switch my map to that serial# and make my tune compatible with that- But honestly, I'm thinking I may just copy all of their data from the AP program into Romraider and uninstall the AP entirely, and flash the new open source map onto the ECU...I intend on either installing the new AP or going to open source either way, but I would really like to get it out of limp mode in the mean time..)
That being said, any help would be greately appreciated!!!
