Coolant Temp Sensor Question
When the coolant temperature is below about 40*F, my coolant temp reads wrong, which I think is screwing with my ability to tune the cold-start.
I've tried the numbers from brainiacs write up, and I've tried the numbers from DIY's site, and I think I tried a third set once from some other website, and I don't actually remember which numbers are in there right now.
Last week it got down to about -10*F, which left it at about 0*F in my garage, but the coolant temp still read 16*F. This error gets smaller as the temp in the garage rises, but it's pretty consistent day to day.
Is there some way to fix that problem? I'm using the stock mazda sensor. FWIW, the GM IAT sensor reads right on at those temps.
And these readings for cold starting are taken when the car's been sitting at least overnight, usually a couple days.
