Fuel temp sensor output voltage info needed
As I start to troubleshoot my system, I would like to know normal/typical fuel temperature sensor output voltage values (as read through the PFC Commander) for cold start and normal operating temperature. I know this will be different case by case based on different temperatures, I just would like to get a general idea from a car that is running well for the voltage spread from cold engine to normal operating conditions.
If someone could post this I would really appreciate it.
Thanks in advance!

I think the specs are in the shop manual. If memory serves, the fuel temp sensor is just there to bump fuel pressure up to assist in hot starts. There's a solenoid that switches the fuel pressure regulator from vacuum to atmospheric.
There may be some other minor map corrections as well.
In general, if it's putting out a signal and isn't open/closed circuit, it's fine. I don't think I've ever seen a bad one.
