Well, electrical gremlins have reappeared.. Hoping to enlist the resources of a local custom auto shop to assist.

Sounds like an intermittent wiring issue. It's worth jiggling and moving the PCM and e-shaft plugs and the harness in between them while running your electrical tests above if you haven't already.
Don't know how much an E-shaft sensor is, but may be worth replacing that to rule it out.

Another less likely possibility is the PCM ground connection may be flaky, but I expect you'd see a number of other symptoms if that is the cause. May be worth cleaning up some of the chassis ground connections anyway.

Good luck.

Reassembled everything and whala... the worst kind of fix IMO - having no idea what resolved it; but the CEL is gone and she's purring like a cat. I'll take it... , but don't trust it.
Jimmy, Thanks for the suggestions. My thoughts exactly. I walked thru the above t-shooting the first time these issues surfaced. So, plan to take it to my local custom auto shop to t-shoot & resolve it. They do good work.
