I'm assuming your fan mod has the fans on all the time.
Perhaps the sensor died, and the previous owner just tied it in to a switch hot circuit?
The coolant temp switch died on my ZRX. So I just wired in a manual toggle on off switch. When it's hot, I turn it on. And leave it on.
I thought there was an ECU option on the SP2 that set the fans to go on all the time. Is that it.
