Thanks for the reply. It’s a 2013 May build. I am the second owner. First owner had the kit installed, including the ecu flash. Says the fan worked. It hasn’t worked for me. I found pin 15 (from the uc kit) was pushed back into the connector and probably not making contact. We fixed that and thought that was it. It wasn’t. The temp sensor goes from 2.5k ohms cold to 25 ohms hot. Seems like that is enough of a difference but I don’t know what those results should be. The speed sensor seems to work because the speedometer works. I can ground terminal 85 on the relay and the fan runs, so everything downstream works. Relay, fuses and the fan itself. I measure the temperature at the sensor at about 250 degrees Fahrenheit with the car sitting still but the eco is not grounding the relay. It’s also not cutting out engine firings as it would before the ecu flash.
Thanks for the sensor wiring info as I will check to make sure there is no brake in the wiring.
Is there readily available software or readers that allow you to see what the ecu is seeing?
Thanks,
Neil
