I've read the codes for my SES light issues and have to replace the TPS. It's mounted on the bottom of the throttle body with inaccesible screws. To replace, the throttle body has to come off. Some fiendish ghoul designed the TB with three fasteners. The bottom fastener is covered by a bracket which is held to the bottom of the intake manifold by two fasteners. I cannot get the left most bracket fastener off because the exhaust manifold obstructs any socket or wrench (1/4", 3/8" with wobble extension, regular & deepwell tried of both sizes). Why this is designed in this manner, I cannot tell you but I've just about given up. PLEASE someone tell me how the TB can be removed without completely removing the exhaust manifold.
