Even if your engine is blown, you can still test it.
First record the close and fully open TBS values for the stock unit.
Take notice of how the values change as the throttle is floored.
Install the new unit and adjust the low values as close as possible as.
Then test it as you did the stock unit.
Post the results.
I would like to get a new TPS as a backup in case mine goes bad.

I made a substitute TPS using one for some Toyotas/Lexus's. Stock nbr is 89452-30140, AutoZone / Wells nbr is TPS4107.
Required a different connector and switching two of the 4 leads. It ran ok but the two voltages were way off, when rotated for first engagement, the low was 1.19 v, the high was 3.09, and when the throttle is fully
opened, the voltages were a little low.
Their are some Mazdas from the 90-200N year that use the same size as the TPS4107. Such as the MX6 - Wells TPS481.
I spent a couple hours on the net trying to find Toyota, Lexus, and MX6 manuals but with no results. This included multiple forums.
All we need is someone with access to old Mazda manuals to find similar voltage range as our FDs.

But the Toyota/Lexus wire/spec is closer to OEM(4 wires)
Assuming they are both actually fit
Has anyone tried the 1995-2002 2.3L V-6 Mazda Millenia S (Supercharged) same connector and 4 terminals?

The TPS is now part of the Classic Mazda Restoration program and you will be able to buy new genuine ones from February 2021. They need to purchased from Mazda dealers in Japan, but that can be arranged through one of the many parts agents who offer to buy parts from Japan on behalf of overseas customers.
In the meantime, Raceonly in Australia also sells a suitable replacement part.
