I've only had my '02 TL for 2 weeks now, but the outside temperature gauge has never been correct yet. It is always about 6-8 degrees F too high. I thought this might be due to the hotter surface near the road (in Texas the air temp is at 90-95 midday and hotter near the street surface), but I checked it this morning at 7am in my garage and driveway and it still was about 8 degrees high (air temp was 70 and sun was barely up). Is there a way to recalibrate or reset the gauge? Or do I need to go back to the dealer on this?

------------------

 

Welcome aboard.....
The answer is no....
I am sure the outside temperature gauge cannot be reset...

 

Yes. It can be adjusted. I don't remember how tho. Mine was right so I didn't do anything. There was a post about it long time ago. Maybe you can do a search for it.

Or can someone help this guy out??

yes, I would like as much info as possible on this. My car always shows the wrong temp. I cant take too much heat, so when my car says 90 I begin to faint. =) Even though my co-worker says that it's only like 70. I see 90 therefore I feel 90.

 

I do get some adjustment in the temperature reading after I've started moving. The dealer said you need to be going over 19 mph to get an accurate read, but even taking that into account I still have the same differential. Several days last week my gauge showed between 97 and 102 F during my entire 1/2 hour drive home, and I know it was only about 90-92 outside. Thanks for the tip on the adjustment. Please go ahead and post the other procedure, because who knows how my gauge is going to react when it gets cool here (sometime around Dec.) and I would like to know what else can be done.



------------------

 

In a 2001 can the temo read above 99, I have never seen it go that high and it doesn't look like there is a 1 next to the other 2 digits.

 

My 2000 can display temps of 100+... I don't imagine they'd have changed the display for 2001 but anything is possible.

Try shining a flashlight directly onto the temperature reading and see if you can see space for the first "1".

Dang......I was wrong.....

 

Thank you Acura for putting the outside temp gauge on the engine.

 

You can indeed adjust the temp as described above. Mine was only 3 or 4 degrees too high and I adjusted mine and it's just perfect now but I must drive for about 10 minutes above 20mph to get an accurate reading. Just sitting in the garage will always make it read way too high even if the car is cold. I don't understand that but it's true. Sitting in traffic doesn't seem to make it rise abnormally either--whatever!

The sensor isn't on the engine, it's in the bumper area. I think they placed it there to keep it out of direct sunlight.

 

I know that it CAN be adjusted, I believe the maximum is 3 degrees at a time.

I remember that it is done with the select/reset buttons used for trip odometer. If I can find the instructions on exactly how to do it, I'll post them up.

Keep in mind that the gauge is only accurate when you've driven for a few minutes. It will reflect road heat for the first few minutes after starting your trip, but will gradually adjust to the actual temperature. Whenever I park and first get in the car it reads as high as 113 (in the relentless Florida sun) but after a few miles it goes down to the actual temperature.

As far as adjusting the gauge -- you can. With the car running hold the SELECT and RESET buttons for the odometer. After several seconds you'll notice the temperature display "scrolling" through numbers, i.e. -3, -2, -1, 0, 1, 2, 3. Release the two buttons when the desired correction factor is displayed. (i.e. if you feel the gauge reads 2 degrees too high, release the two buttons when the display reads "-2"). You can repeat this procedure several times if you need to alter the reading by more than 3 degrees in either direction.

Finally, there is a manual way to recalibrate the sensor that is described in the Helm service manual. It involves physically removing the sensor, but if any of you would like scans of the actual procedure, I'd be glad to provide them.

Nate is just joking around....

 

Mine is worse than yours in my 99. It always says 112F or something around there. I know I live in florida but it is not close to that hot.

 

I know, but it might as well be. Couldn't they put it somewhere cool, away from the engine? I've had passengers comment on how far off the reading is. I just mumble something about having to be going 35 MPH.

 

Yes, thr '01 can read above 99. Mine was up to 112 once (Texas heat).

I made the recommended adjustment and it worked fine, but you cannot adjust more than +/-3 degrees. I adjusted it down -3 degrees, then actually waited 2 days and tried to adjust it down an additional -3 degrees. The computer knew that I already did that once and didn't change the temp any more. Oh well, at least its closer. I'll have to do mental arithmetic everytime I look at it.

 

My 99 TL temp gauge can read over 100 degrees also and it is pretty accurate too.

I've got a 2001 and the highest I've seen mine get to so far is 113... OUCH, that's hot!

I could have sworn I read that you can "correct" the reading more than once, but I guess I was wrong.

Recently the battery had to be taken out for a few minutes and of course the radio had to have the code put in and now i've noticed the outside temp is not on. How do i get this started back working?
thanks

 

HOLY MOTHER OF 14YR OLD THREAD REVIVAL!


And what do you mean the temp is not On? taking out the battery should not stop the temp sensor from working once its back in the car.

 

all I know is its not working and I am wondering how to get it back to working?

 

What does the temp show?
If it reads something like "---" instead of " 86" it means the temp sensor was unplugged for some reason.
The sensor is easily located at the front of the bumper behind the license plate, Just stick your hand in the lower air ram and you will find it.

 

Temp sensor doesnt get reset or turned off when disconnecting the battery. If its not on now check the wiring going to the sensor.

 

Ok thanks...it's not showing anything at all

 

For troubleshooting we need to know exactly what it shows!


This is an Unplugged Temp Sensor: "---"
This is a Functioning Sensor: " 85"
This is not normal: " "


The temp sensor dial has 3 spaces for numeric read, It must show something. But 3 blank spaces is not normal. Perhaps the Temp sensor is dead?

 

For fun, try disconnecting the battery, waiting 30min, then reconnecting. If I had a dollar for how many times power cycling things solved the problem.

 

There is nothing showing at all where it showed outside temperature

 

Try what "thelastaspec" mentioned, perhaps there is a fluke somewhere? Its very odd to have the temp sensor fail.
