I figured I’d disconnect the connector to the APS and hook up a ohmmeter while twisting the throttle. If it shows up in the APS that has to be the cause. If it doesn’t, I should be able to manually operate the throttle shaft to see if it’s the TPS the same way. Never tried to manually turn the throttle shaft. Hopefully the servo motor doesn’t inhibit that.

Hate to spend an extra $130 on the TPS if it only needs the cheaper APS, though changing that looks like a bear.
