    In response to Shepherd

Sorry for the delay in my response. I did get my hands on a pretty top-notch scanner to dig a little deeper. I checked the TPS voltage at idle, and watched it as the engine warmed up; at idle it stayed steady at 0.69 volts, and when I gave it some throttle it increased to 0.92 at 2000 rpms, and roughly 12% throttle. Also, the scanner did confirm closed loop after idling for a little over 5 minutes. If I understand the DTC correctly, a code should only trigger a "high voltage" error on the higher end (closer to wide-open) reading compared to the maximum of roughly 5 volts. Again, I have no codes. Seems like I may want to investigate further; proportionally, that is a long way from the 0.45~0.5 volts that is typical. I will need to consult my service manual to double check the spec.
