Re: Engine Temperature Sensor. Hunting Revs
It's on top of thermostat housing ... take off engine cover and remove air intake pipes. Simply unscrews from body. There are pics, etc on my website (link in signature below). Duff sensor will not help as ECU will be altering fuel mix to compensate ... so when low, over fuels/rich, etc.
You should be able to hear the actuator tests taking place ... lift the bonnet and listen.
