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.
