ECU pins are 11 17 30
you should have 300-600 Ohm between 30 & 11
between 30 & 17 also 300-600 but this value should drope to 40-150 ohm when you are WOT

another smart thing to do would be to get a spare TPS and plug it (without removing to old one) and move it manually while looking at the SECS

if you still have wrong value the common failure point of the loom is at the two big multiplugs near the coil lots of people cut and solder this part
