IC7 has purpose , ask
it's only purpose to to keep IC17 and its transistor from blowing up , with simple wire shorts on TPS.
on one PC the copper (PCB) traces to the IC7 were blown to hell, just B6 trace.

Fixkick et al----Seven months into this hot wire fix, all is well with this fix as described, 7000 miles so far, no further issues. I did go on Ebay and found a very small digital voltage regulator, adjustable, 1/2" x 3/4", which can replace or augment IC 6 (or IC7?) and provide 5 VDC to the TPS.
Question for Fixkick: The diagnostic code set indicated the TPS failure, BUT...will the failure of IC6 to provide power to the TPS be shown as that same code? I am starting to suspect the TPS is OK, and it was the IC 6 failure which caused the TPS code, ( I think it's 21,22). Thoughts on this? Thank you in advance.

the +5vdc REF, is not ever optional.
when 5v goes to 0v, the sensors go dead.
for sure TPS, will show TP pin too low,
fix +5v dead first, (only 2 causes, of that bad ECU or a sensor is shorted, (wiring is top reason for shorts)
the ECU Is so dumb it does not check +5vref pin first. and make it a low number DTC error , sadly it only shows sensors dead, and only voltmeter tells the the real truth. here.
cheers and good luck to you!!!
