Can someone PLEASE tell me how best to test that these sensors are operating correctly (and where to test from)?

- Cylinder Head Temp Sensor

Roughly 3K ohms cold to 300 ohms hot.

- Flywheel Speed Sensor

you need an ocilliscope to check the operation of these sensors, you need the o scope to check and see the sine wave given off from the sensor when engine cranking or running

Is there a simple Ohm/Volts test that will confirm if these are OK?

What point(s) do I test from?

Some guidance appreciated [/B]

check from the sensor itself to see if the sensor is working then from the dme to verefy no loss through the harness
