TPS replacement

No, not the TPS report from Office Space but the throttle position sensor in my daughter’s 1993 Olds Ciera.
The Check Engine light was on last time she was here. We read it out with the Actron CP9135 scan tool . The code 22 indicated that the voltage on the TPS was low. Since this is a 1993 Oldsmobile Ciera, replacement was probably indicated.
She brought the part with her for this visit.
The TPS on this 3.3 MFI engine faces down toward the upper radiator hose pipe. No clearance for a normal screw driver. If we had had a flat ratchet offset style driver, that would have been ideal. Lacking that, after disconnecting the battery and removing the air cleaner and its mounting plate, we used a needle-nose vise grip to break the 2 screws loose. Then used a #1 Phillips tip in a holder to get them out. Replacement was a matter of holding the screws in the TPS while aligning the paddle that is pushed by a similar paddle on the throttle shaft. Starting both screws by finger, running them in with the mini screwdriver and snugging them with the vise grip. Reconnect the battery and test. Put the air cleaner mounting plate and air cleaner back on. Clamp the air inlet hose where the strap had broken and done.
