I would take the tape out, but unless you taped the copper crush washer too, the sensor should ground through the washer.

It's easy to check. Check the resistance between the head and the body of the sensor. If there is no resistance the tape is not causing a problem.

I would also check the resistance between pin 5 of the ecu and the body of the sensor. There should be no resistance.
