Steve, voltage from the TPS is not a function of the ECU, but the TPS
itself.  I think I remember someone having this problem in the past and it
turned out to be the TPS was bad.  I cannot remember for sure though.  You
might try an archive search (like I said, it rings a bell but I'm not
certain) or perhaps someone else can confirm this.
