PS so far I have found 3 temperature senders on the Zetec. 1 is above the thermostat, 2 is in the air intake and 3 is a small one down on the lower engine block. All are routed to the EEC unit so it is the computer thats decides the dashboard guage position
Hi Madmole...
You said there are 3 temperature sensor on the Zetec ?? I changed the one in the thermostat. How can I know each one is the wrong one ??? I really believe I have a bad sensor... my fan is kickin on very late... when the gauge hits the " L " . I don't like it doing that...
