it was a 1 pin plug btw...
A new IACV should do the trick. I purchased a ebay IACV for D16Y8 and it fixed the issue when multiple cleanings of the IACV did not.

1 wire sensor is the Engine Coolant Temperature sending unit for the gauge cluster. Good deal though.

Code 41 Oxygen Sensor Heater Circuit Loose Wiring.

I replaced the O2 sensor with Bosche last month. Throwing this code...
Might be a dud?

otherwise, engine turns on perfect and low idle.

If the sensor is new, try the troubleshooting steps in the factory service manual to find the issue.
