Great timing on your reply! I'm just in from the garage to diagnose the issue.

The sensor wire was either pinched or just rubbing against the mounting bracket for what I think is the starter solenoid. The insulation was rubbed clear thru and the wire almost severed. I'm thinking it was shorting out so no signal to the ECU. I did not have a new sensor so I did a simple electrical tape wrap job on it. I'll order a new sensor if the light comes back on. Can't explain how the sensor wire came to be in that position as I've never done any repairs in that region in the 14 years I've had this car.

And no smog test in my state (MO) for car of this age, so one less thing to worry about.
