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.
View 19 RepliesSo, 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.
View 6 RepliesMy 2013 is always off by a few degrees (too warm) on the outside temperature display. This is not the sun or other outside influence. I wouldn't mind if it was just a couple degrees but it is always 5-10 degrees off. Can this be adjusted?
View 12 RepliesI 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.
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?
View 13 RepliesI 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.
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 RepliesI 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!)?
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 1 Replies1991 Ranger STX, 4.0. Had a leak from the rubber seal on the thermostat. Changed the thermostat (stat 195) and seal. Now my temperature gauge is not showing a constant reading, goes to half way and when the thermo opens the gauge falls down to a quarter. The gauge is cycling this way every time the thermo opens.
View 2 RepliesJust bought a 2002 Prius for my daughter at an auction and the car has been driving fine the last few days even though the hybrid warning light has been on and off. Found no fault code with OBDII. Found out later from Toyota service history the cause of the hybrid warning light was a leaked hybrid battery. The previous owner disposed the car off at the auction before the problem was fixed.
I was driving today and the coolant high temperature came on and I can't rev/drive. Stopped engine and re-start after a while and coolant high temperature warning light gone. Drove a short distance and coolant high temperature warning light came back on. Used a OBDII and found no fault code. Radiator hose by the radiator cap is cold but hose at the top right side of radiator by the hybrid system is hot. Opened radiator cap and it is full of coolant.
The car has been serviced on 12/26/2012 before it went to the auction. Can air pocket trapped in the radiator cause this coolant high temperature warning light and can't rev/drive problem. Also today is the first time we didn't use the heater. We used the heater to defog the windscreen and heater work.
I was driving my 2007 Prius on the freeway this morning after picking it up from my mechanic and the high coolant temperature warning light came on for ~4-5 seconds but then disappeared. I was able to safely drive it another 5 miles to work and park. My mechanic changed the engine and transaxle fluids in my car (along with pcv valve and serpentine belt replacement, engine oil and filter change) just before, so we think this could have been due to an air pocket in the coolant system. I will need to check the coolant level once the engine has cooled down and refill if necessary. I plan on driving it around locally before going on the freeway in case the warning comes on again.
View 11 RepliesJust wondering how accurate the digital gas gauge on the Prius c is? My current 04 Prius has a notoriously inaccurate gas gauge: It often gives me an incorrect reading showing much less fuel than I actually have. It is even worse in the winter.
View 19 RepliesMy 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.
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...
Just wondering about the "miles to empty meter", should I disregard it when I have high mpg? (50-60 mpg)
View 6 RepliesOur city has installed a number of auto-radar "you are traveling ___ mph" stations in the last couple years. While not the most accurate of devices, so far they seem to be reading me slower than my C speedometer says. Any other C drivers noticed this? I have the standard 15" steel wheels on my Two.
View 12 RepliesI've recently purchased a 2007 Prius and have been tracking my gas mileage. I've been comparing what the computer says and what I get by dividing the miles since last fill w/ the number of gallons to fill. I always reset the computer and have always let the tank get almost empty (flashing fuel gauge). I consistantly calculate 2-4 MPG LESS than the computer reports. I talked with a friend who has a (I think) 2006 Prius and he does the same but his calculations and the computer usually within a few tenths of a MPG. I took my car into the dealer today for the accelerator pedal recall and asked them to look at the MPG. They could find nothing wrong and said that was "normal" I'm not convinced... What do the rest of you see?
View 14 RepliesI filled up for the first time yesterday after driving 1,039 miles. I had almost forgotten how to do it. Anyways, the reason I thought I needed to fill up was that the gas gauge was down to one bar. However I was only able to add 8.3 gallons. I thought 1 bar=1 gal but that turned out to be inaccurate.
View 18 RepliesThis is kind of a strange (minor) issue, but I noticed just recently that the outside temperature reading on my 2012 Sonata GLS is registering about 10 degrees hotter than the real outside temperature. This is driving down the road, not parked in the sun. It showed 91 degrees the other day as I was driving home from work, when the actual high for the area was barely 80.
My thoughts were that something was blocking or covering the sensor for the outside temp reading, but don't know where that sensor is located to check it...or if there might be some other way to "reset" the temp reading?
Just purchased a 2008 2.0T Passat wagon, lux version. I believe my speedometer may be reading high by about 4 mph. I seem not to be keeping up with most of the traffic (assuming they are driving close to the posted speed limit). Not sure how to really check this out, but assuming the mile markers on the interstate are accurately spaced one mile apart, at 60 mph it should take me 60 seconds to cover the distance and at 70 mph it should take me 50 seconds to cover the distance. If my thinking is correct and upon doing that I find that it takes me about 66 seconds to cover the one mile at an indicated 70 mph on my speedometer
.
Is my thinking correct and/or is there another way to check? Have never been able to find a shop that has calibration equipment so I just resort to this method.
