Plain Jane OEM nothing to see here rebuild

Wish I could help you out with those questions...

Mines is an S4, and I haven't messed around with an S5 with the E-OMP to get enough info for you.
I vaguely remember the full-range TPS doesn't matter so long as it's linear...?

Yeah, it's linear...no drops in the range on either full or narrow. I've heard an osciliscope is a better test and if it's as easy as borrowing the tool and hooking it up I'll test it that way.

As long as it's linear, with no drop outs its should be fine. Referring to '89 FSM, page F2-81 cites a resistance measurement spec for the TPS, full & narrow ranges. To test, disconnect the TPS connector, and measure resistance across the TPS connector terminals it references at closed & wide open throttle conditions. Do this with the engine at operating temp OR you can use a screwdriver to lift the fast idle mechanism off the thermo-wax plunger so the TB is not sitting at a high idle for the closed throttle measurements.

Full range TPS @ wide open throttle should be 3.4 - 5.1 K-ohms; at closed throttle it should be 600~900 ohms. The narrow range is 0.8~1.2K ohms closed, and 4.0~6.0K ohms WOT.
