Pontiac Workshop Manuals Fiero V6 173 2 8l 1986 Engine Cooling Here is how the fiero cooling fan system works. the enine control module (ecm) provides a ground path to energize the fan relay, which turns on the cooling fan. the ecm will command the fan on, when coolant temp is above 108°c (226°f). when the engine cools down to about 101°c (213°f), the ecm de energizes the fan relay, and the fan stops. Member since dec 2009. there are four seperate temperature sensors on a 2.8 v6 fiero. cts used by the computer only two wires yellow and black this sensor is the only one that could affect the idle. if the cts sensor is bad it's bad info could be causing the ecm to think the engine is cold, which could be causing the high idle.
