Prius (2004-09) :: Outside Temperature Reading?
So, this may sound strange but from the get-go of owning my Prius I have always sort of doubted the accuracy of the outside temperature reading. I am not totally worried about that part, as I don't really care about the reading, but I would love to understand something. When the thermometer reads the temperature as "37 degrees" it displays this bar that states it as such. The same bar where it notifies you if you change the temperature or volume via the steering wheel. So, I guess my question is , is there something specific about that number or is it just a quirk of my individual Prius? Also, it is worth noting that no other temperature causes it to display this message, only 37 degrees.

The outside temperature is reported inaccurately by your C? I now automatically deduct 5 degrees from whatever my C tries to tell me is the temp. I may mention this at my 5,000 visit to the dealer because I'm wondering if the sensor is placed too closely to something creating warmth. But....it's definitely reading too high.

I bought my 2011 Prius III back at the end of December and so far have had 3 fuel ups. Not counting my first tank, my second tank I got 44.4 MPG calculated with mindful driving (driving slower and pulsing and gliding etc). The last tank however, I decided to drive a little more like how I drove my previous car (2001 Lexus ES300). This last fuel up resulted in 41.4 MPG calculated. I feel like I have to work quite a bit to keep it above 43 MPG. I am located in Southern California Orange County, however 90% of my driving is NOT in Socal Traffic. I also changed my oil to Mobile 1 Synthetic Enhanced Fuel Economy yesterday at 1200 miles.
I also have read a lot about break in at 3k-5k, which is keeping me hopeful. How much can I really expect, if any at all? I am not sure what to think on this because as with the people who have experienced good jumps after a break in, it seems there is an equal amount of people getting great MPG right off the bat.
- What fuel economy are you getting and how are you determining fuel economy? (trip computer or manual calculations) 42.9 average for the last 2 tanks - calculated
- What fuel economy are you expecting and why? 45-48, brand new car and adjusted driving techniques. I was hoping for 50+
- What are the approximate outside air temps? 55-80
- How long are your trips? Daily, about 3-5 driven. Weekends 80-160
Lexus GS 2013+ :: Factory Adjusted Headlights Too Low?
Headlights are factory adjusted too low? Maybe it's just me, but I don't believe the headlights are factory adjusted high enough because the headlight coverage distance is not as good as I'm used to seeing. I believe I will adjust my headlights for a slightly higher (upward) aim to see if it improves the distance the headlights cover.

I have a 93 accord ex sedan, 4 cylinder, automatic that I bought in August. I live in South Dakota & it's starting to get cold here. When I first bought the car the temp gauge was working fine in that it would move to the middle of hot/cold range. Recently, I've noticed the interior doesn't get warm for awhile, even after driving 20 miles. It blows warm air but it seems like it should be warmer. I've also noticed the temperature gauge barely moves, if it does at all. Most of the time it doesn't move or just stays on cold. I did some research on here & thought I would try to change the thermostat, upper & lower hose and the antifreeze. I'm hoping this will heat up the interior better because it's starting to get cold here & fix the temp gauge.
Previously, I had a 91 accord & that would warm up great, even when it was bitterly cold here. What would cause the temp gauge to do this? I'm even thinking about changing the transmission control module because I read on here that could cause the gauges to have wrong readings. The speedo & rpm gauges also seem to have wrong readings, especially in the mornings or when I first drive it. I used my gps & found the speedo to be off by as much as 10 mph. The other item I've noticed is that I only get around 23-25 mpg highway & on my other accord I was averaging 28-30 mpg highway. Not sure if this is related or not but thought the more info the better.
I have done all the basic maintenance-oil & filter, plugs & wires, valve cover gasket, air filter, tranny fluid but have never done anything with the heating/cooling system.
Sierra :: Temperature Gauge Running Low / Reading Cold
Tempature gauge on my 2001 sierra (4.8) has been running low for awhile. The highest it will reach is round 160. It's currently running rough/rich and bad mpg. I replaced the ECT sensor but didn't work. I'm not sure if there are two ECT sensors on this model. I don't think it's the cluster. Is there a second sensor I'm overlooking?

I have a 2003 Passat and the engine temperature gauge will read 190 normally and then suddenly drop to almost zero, stay there for a while then head back up.
I purchased a temp sensor to replace the old but for the life of me I can seem to locate it. I know it's in the back or rear of the engine somewhere.
BTW, the car has the 1.8 engine.
Ford Super Duty (1999-2016) :: Transmission Temperature Reading Low?
With the colder temperature, I noticed the temperature for the transmission is not getting up to normal as quickly as before. Yesterday I switched to gauge mode and it showed 145 degrees after 20 miles of driving at an outside temperature of 42 degrees. What the minimum temperature should be? It's not showing a check engine light and shifts good.
View 8 RepliesToyota - Highlander-hybrid :: A/C Stops Cooling When Outside Temperature Reading Exceeds 107 Degrees
I read in a different vehicle forum that, in vehicles where the A/C condenser is mounted in front of the engine coolant radiator, when the engine coolant temperature reaches some near-overheat limit, the onboard system disengages the A/C compressor clutch so its condenser does not preheat airflow going to the radiator in an attempt to avoid overheating.
Is this the case with the Toyota Highlander (and specifically in a 2008 Hybrid Limited)???
I've recently been experiencing loss of A/C cooling when the center console outside temperature exceeds about 107 and the dashboard coolant temperature gauge is almost midway up towards H, but still closer to C. But once the outside temp reading drops back below 107, and I restart the vehicle, the A/C is once again cool.
Since coolant temperature is likely is impacted by higher outside temperatures, might the coolant temperature sender be failing or simply aged such that it is out of calibration, falsely indicating too high a reading?
How difficult is it to replace the coolant temperature sensor? Where is it located (in case it's just a corroded connection!)?
Camry :: Temperature Gauge Reading Stay At 4th Mark When Engine Fully Warm Up
I have 2002 Camry 2.4L (2AZ-FE Engine) Japan built. Lately, I noted the temperature gauge stay at the 4th mark when engine fully warm up (first mark is at bottom and slightly longer than the next few marks), is this normal? Which mark it is at when fully warm up.

View 2 RepliesCamry :: 2004 Car Running Rough - Temperature Gauge Not Reading Hot But White Steam From Hood
My girlfriend has a 2004 Toyota Camry SE, 2.4, 4 cly, with 198k miles. All maintenance has been done per book guidance since she has owned the car. The other day the car began running really rough on her way home. as soon as she put it into park and lowered rpm the car stalled out. temperature gauge did not read hot, but noticed white steam comes from hood when i seen she pulled up, Opened hood let cool down and coolant looked nasty as heck. So I did coolant flush and replaced the thermostat as per advised from parts store. Did not make a difference because during test drive, half mile down the road, car temperature gauge was reading hot. Shut the car down waited 10 to 15 minutes and drove back home.
Altogether drove roughly 10 miles max in hot condition is stop and cool down and go again mode. Also note, this is the first time using a forum of this sort. Along with, I'm not a mechanic as some are, but I know my way around a tool box no problems. I'm on the verge of just ordering new water pump, belts, fans, fan relays switches, radiator and all since I'm going to be in there to fix it anyways.
Ford 7.3L Power Stroke (1999-2003) :: 2002 F350 - Outside Temperature Gauge Reading Wrong
I have an 02 f350 7.3 power stroke...Yesterday I noticed the outside temp was reading wrong,it was jumping from 67 to 86 to 92 back to 67..Temp was prob around 90 with high humidity and my a/c was on..So I got to where I was going and when I restarted my truck to go home the fuel gauge dropped to empty(I just fueled the day before) and fuel light came on and outside temp still wrong on the overhead digital display...Are these two things related???
Stopped the truck restarted it and fuel reads correctly again....Went out today and fuel light back on and on empty...Outside temp wrong again,a/c is on .....I disconnected the batteries when I got home to "reset the system"if there is such thing, fuel gauge working but outside temp wrong..?? Where is the outside temp sensor ?could condensation be running onto the sensor and throwing off my temp gauge? Just strange that both these things happened at the same time......I don't think its a fuse or they wouldn't work at all. I should mention all the other gauges work correctly...

I have a 2013 Prius 4. I'm not sure if there is a problem or not but the heater just seems to blow the same temperature of air no matter how high I set the temperature. The air feels lukewarm. I was driving 60 miles yesterday with the temperature set at 76. I had on a long sleeve shirt and polar fleece jacket and it never got to where I was really warm. Outside temp was about 50.

2010 Prius IV - when I have my ac system off and outside air on the system seems to heat the air to whatever the temperature was last set at? This should be a vent condition and air should be coming in from the outside even if the air outside is 50 degrees and the system was set at 70 when it was last on? The system seems to be heating this air. If I turn the system on and reset the temp lower, then turn the system off the air comes out cooler? Why is this?

As a Prius driver, I have driven my 2012 Prius more than 110,000 miles. I love the car and have a suggestion on improvement - Create new software to allow the driver to monitor engine coolant temperature and RPM from either the dash display or touch screen display.
I like knowing if my car engine is up to temperature before punching it on the freeway ramp or about to overheat before an idiot light goes on.
Prius (2010-12) Fuel :: ECO Mode Coolant Temperature Cuts Off
It has been documented that the computer will let the ICE coolant cool to a lower temperature before mandating it to fire up again to maintain that lower limit.
Why isn't this done in other modes? Is this compromising anything when it comes to emission or engine protection? Since full power is available in ECO mode, one can force the ICE to drive with full output, even when it is a little cold.
