ISSUE:
All Throttle Position Sensor (TPS) mounting screws have a "Pozidrive" head. The "Pozidrive" head looks a lot like a Phillips screw head.
Use of a Phillips head screwdriver to remove a "Pozidrive" screw will normally result in a rounded or damaged screw head. Many technicians
think it is an overtorqued or "frozen" screw. An adhesive was also used as a thread sealant starting with the 1988 model year. This adhesive
requires still more effort to loosen and remove the screw.
ACTION:
To prevent rounded or damages screw heads when servicing the TPS mounting screws, technicians should always use a # 2 "Pozidrive"
screwdriver.
