Cold start and temperature gauge reads hot?
So, it's cold today. -6 F and with windchill it is -21 F. I started my car today no prob
and it was revving high to warm itself up. Then the temp gauge leaped from cold to hot,
and I panicked and shut the car off (the car was running for probably a minute). I'm
thinking it was just the super cold temperature messing with the sensor as my phone
has been left in the cold but battery diagnostics read it as "overheat," but I know more
about computers and phones than I know about cars (and I can feel the real
temperature of a phone easier than an engine), so I played it safe in case I was wrong.
So, why did the gauge do that? Is it something I should be concerned about or would it
have fixed itself if the engine were allowed to run longer?
it might have been that the sensor was confused minus 21 is damn cold ....// the only other thing is to check the coolant level and make sure it is full..and retry it again ......I really think its a freaked out sensor or even a freaked out pcm (power control module) aka computer which relays the coolant temp by a bus massage to the BCM (body control module) anther computer that tells the gauge what to do which is electromagnetic ...so two computers later :)
Looking at those temps sure makes me thankful for lower alabama weather.
LOL I think anything in that kinda cold will act funny...not fun
Haha, last year it was -10 F with -40 F windchill. And it wasn't just for a few days, it was like months. It's been a lot warmer this winter.
I spent four years in Fairbanks Alaska. Beautiful place but way to cold for me in the heart of winter. Sorry I don't have anything to add about your issues.
My dad started the car for me, and he said it didn't happen to him. Probably just a fluke, but thanks so much for your input! :)
