Because the only remaining error code was for the knock sensor (43), I went looking for the knock sensor. It is screwed into the block on passenger side of engine - rearward of the starter. Best view from under car.
Wiring connector was missing and the sensor is cracked. speculation: it was broken during engine removal/install. It was not throwing code prior to engine removal.
Ordered Knock Sensor and Connector from Amazon - $37.35

| A 1995 Oldsmobile Ciera at Pull-A-Part donated parts - FOR FREE! Conduit and short wire with terminal ring was used in this project. |
4/2/15 Update:
After another trip to yard for free stuff I finished up with Knock Sensor today.
 |
| New Knock Sensor Connector |
Also fixed solenoid wire (purple). It was not terminated and frayed wire was wrapped around the solenoid terminal. Obtained a terminal ring and wire extension from yard.
 |
| Purple wire had no terminal ring. Got ne from the salvage yard. |
What's hard to see is the harness repair - bad flex conduit was replaced with some new stuff from the salvage yard. Routing was changed to go under the knock sensor and behind starter. It should keep it away from the exhaust.
 |
| Connector and repaired wires in place. |
Took for a drive to the Inn and back and idled in driveway. Check Engine light stayed off.
