Another fidle to fan issue

Post by ecorl »

All,

I am using the fiddle circuit to turn on my fan on my MSII application. It is set to come on at 190 and off at 180. But in normal operation, it isn't turning the fan on. (Thank god I have a fail-safe and wired in a toggle.) The circuit work fine and does activate the fan during test mode when I change the "fan on" setting to below ambient. Maybe a bad sensor? Thoughts?

The sensor used is presumably the coolant one? Are you seeing a normal reading from that on the Tuner Studio dash?
