ok i tested at my ecu and found that pin 3d is not grounding out at the ECU. the ecu still displays the temperature of the water on my datalogit. DO the fans use the same sensor or is it a different one? Im trying to narrow down if its my ECU or a thermo sensor that tells the ecu when to ground out. There is also mention of the powertrain module or something what does it do in all of this?
