Real experiences from 2010 TOYOTA Tundra owners
Fixed Itvia forum_post
“Help, has anyone ever actually fixed the throttle body issue with the early Tundras? I have found thread after thread with really good information on checking this and that but I have yet to find one that show a fix.”View original
Pro Tipvia forum_reply
“There's a guy who shows this on a Lexus . I took my whole throttle body out and tested it using a bench power supply with 5V which was enough to engage the clutch and run the motor (another reason I don't think you should be seeing 12V on the blue/black line).”View original
Pro Tipvia forum_reply
“I don't think that you should be getting 12V on the wire you mentioned. The Factory Service Manual, at least for my truck 2002, show that as a signal that oscillates on 5v.”View original
Experiencevia forum_reply
“The good news on earlier non-VVTI with throttle cable it seems to just be a nuisance. On later FGTs with drive by wire, I've heard they often go into limp mode with this code.”View original
