I just wanted to update everyone on this.   The blinking has not returned.
I did clean the contacts on my sensor probe but honestly they didn't look
too bad.  I think my foil was probably to blame (maybe making poor
connection at the connector, for example) and that my wiring harness
replacement did the trick.

Thanks again to all who responded!
