I know it's cold in Ontario, but not that cold.
One day we watched the temperature go from 0, to -40 at a few degrees a minute, now it's been at -40 for over a week.

Is it a thermometer under the hood somewhere? Anyone ever run into this?
I don't believe there'd be any ice caked onto anything, we've had a few days above freezing that would have melted anything off.

Thanks for any advice!

Look into your front top grill on the drivers side. See the round circle? Thats it.

Speaking of cold temperatures, where to you find the block heater cold for cold Canadian winters?

 

[MattInSoCal]

Brrrr!

Well, at least it said -40 Celsius and not -40 Fahrenheit, because that would have been bad.

The temperature sensor is behind the grille as has been mentioned in a previous answer. The reason that you are getting the -40 reading is either because the sensor has gone bad or there is no connection to the sensor from the, I'm going to guess because I don't want to look, BCM. You could try unplugging and reattaching the cable to the sensor and see if that fixes it.

The sensor contains a ten-cent (Canadian or US) part that does the job of the sensing, and the BCM (or whatever) reads the small voltage that is generated and converts that to a temperature. No voltage (including being shorted to chassis/ground) = a reading of -40 degrees (C or F).

My car came from Canada and has a stock engine block heater! Or is this on all G6's? Also the tempature gauge is in celsius!

Engine block heaters are an option. They are usually found in the colder states and provinces.

I don't know about up there in the Great White North, but here in the lower 48 we can choose Metric or English measurements via the DIC. The speedo and Odometer change to km/h and the DIC shows kpa for the TPMS and C for the temperature, as well as l/100k and such for economy.

Yeah I can change my speedo from KMH to MPH. But my Tempature gauge is Celsius. I am from Michigan not Canada my car just came from there.

WOW! Lucky, lol -40? I've only seen 130F! haha

Hi all;

Was at the mechanic last night fixing his computer, and he threw the car up on the hoist to take a peek.
We couldn't find the thermometer for the life of us (within the 30 min I was there)
He says they normally look like a "cone" ?
We couldn't see it in the place you guys suggested, wondering if anyone has a picture of it by any chance.

It's not life or death, it's just a minor nuisance.

On the plus side, found out why my headlight went out, someone crushed the wiring harness when they put the headlight back in, all good now though

 

[markpetersonii]

I've never looked to see if I could find it but good thing about your headlights!

Don't forget if it's Canadian spec, you also have the wonderful day-time running lights! I have the block heater, the cords barely long enough for it though, have to open the hood to plug it in safely if it's dark out. I don't like the metric system, but I love Celsius. Unlike Fahrenheit, '0C' is freezing, where as 32F is freezing, and it's technically 'above freezing' if you know what I mean. Anyway, almost all vehicles in Canada come standard with a block heater (midsize class and above). It's optional on some import brands in all size classes only so they can make a few extra bucks off the sale. I only use the block heater a few times a year, mostly when I travel farther north.

On my 2009, it's near the left headlight. Just for you, I took my grill off to take a picture.

If it was your left headlight that was out, you may now know why your thermometer is not working as the wires run in more or less the same place.

Thank you so much for the pics.
I definitely do not have that part inside my driver side grill.
It was the passenger side headlight that had the wire problems, so that doesn't help much either.

And as of the last few days, the thermometer has been going up and down a few degrees, so it's like it's still working, it isn't always staying at -40. It won't ever get any warmer than -25 (which it's nowhere actually near that temperature outside right now), but it's not sticking at -40.

Oh well, she goes into the shop tomorrow, hopefully they can have a look.

Thanks again for the pics, much appreciated. Hopefully it's not as cold out where you are, taking parts off in the cold is no fun.

edit: then I look at your screen name again... haha

My pleasure.

I still vote for it more likely being the sensor, though it could be the connection. Now that you know kinda-sorta what to look for, you can look for something similar. It is going to be somewhere that is shaded from direct sunlight yet still in the high-pressure air path. You may not have noticed just looking but part of the design of the sensor is designed as a heat sink so that the whole assembly changes temperature somewhat gradually.

Yeah, it was maybe cooled down to 23 C when I took those shots. Had to run the A/C in the house the last few days.

But it is usually well over 35 most summer days, and can hit 40 easily.

We actually very badly need more cold weather and snow.

I'm adding a mirror to my car with the temp display on it. Is there an easier place to tap into this wire to get my reading to my mirror? Thanks.

 

[geewhiz]

You should start a new thread.

Where is the mirror going to be, out side or in?

In Arizona, my temperature display quit working. Would disconnecting, then reconnecting the car battery reset it? Thanks.

that's likely a bad sensor or harness issue.
