Outdoor temp gage

[rc51ny]

My outdoor air temp reading is usually 5-8 degrees warmer that actual temp. Does the sensor need to be moved so it's not picking up engine heat? Is it just my RT or do others have the same issue? Thanks

[samewok]

I would not because the spyder uses this reading.

[dave01]

Mine did the same thing, reading a little warmer than real temp. I had a second one that was built into the Whistler radar detector and placed the sensor in front and down low to get a true temp.

[ARtraveler]

The reading seems to be a little high compared to the electronic temps you see posted once in awhile. There is also a difference sometimes of two degrees or so between our 2010 and 2011 when we go riding down the road together.

I don't recommend messing with the sensors either. The gauge gives a pretty good approximate--but is not perfect.

[PrairieSpyder]

I was going to post about this too. I have the same experience -about 6-8 degrees high. I stead of moving the sensor, i was thinking it could somehow be calibrated.

[NancysToy]

The sensor cannot be calibrated, and it should not be moved. To see if it is accurate, compare the temperature after the Spyder has sat in the shade for at least 4-8 hours. In the garage after "sleeping" overnight is easiest for me. If it is off by more than a couple of degrees then, it should be tested (verified) and replaced by the dealer.

The sensor also contains a barometric pressure sensor. Moving the sensor into a direct air stream or low pressure vent area can throw that reading off, which could adversely affect the fuel injection and ignition timing. If you are not having engine management issues, the pressure function probably doesn't need to be tested.

The best thing to do with an errant temerature display is to ignore it. Like the weathermen on TV, they all lie!

this is just one of those "suck it up, and move on" items. mine has NEVER read any degree of accuracy, dead on. it's usally off by 3 to 5 degrees, right out of the stall.

[prmurat]

Mine has started to act up this weekend, stuck at 75 even in the evening...took 3/4 hours to get to real temp, around 62... where is the sensor anyway? easy to change?

I dont think in works for ambient temp. I think its just for the engine mapping, but I could be wrong

The AAPTS sensor is to measure Ambient Air Pressure and Temperature. "Ambient" is a relative term. In this case it means air inside the body, near the air intake snorkels.

[Rar]

Mine consistently reads up to 8 degrees warmer than it really is. I don't pay any attention to it.

Moving the sensor into a direct air stream or low pressure vent area can throw that reading off, which could adversely affect the fuel injection and ignition timing. If you are not having engine management issues, the pressure function probably doesn't need to be tested.

As stated above, if this sensor is reading incorrectly, it may give the incorrect information to the computer. This could cause all kinds of performance issues. I would think that getting it fixed would be something that should be done.

It doesn't do as much as you think. Part of the reason these read high is that the temp inside the body is higher than the outside. The sensor is likely reading more accurately than it appears. The only way to tell is to check the reading when the Spyder is cold and has been sitting for several hours. That reading should be within two degrees of the actual air temp. I

t takes a pretty gross error to affect the mapping or timing. The knock sensor and O2 sensor(s) can compensate for most errors. The pressure sensor, along with the MAP sensor in the intake, has more affect on the mixture than the temp sensor, as does the O2 sensor in closed loop conditions. Sensor error that is great enough to adversely affect engine management is usually very obvious in the way the engine performs. If the engine is running too lean, you will know it!

[rc51ny]

Thanks for all the info guys. Just sounds like I ignore it and move on. In any case, with it getting colder here (high 50's low 60's) it will make me feel warmer as I ride!!!

[Bob Denman]

This is actually pretty simpld:
If your gauge is reading 100 degrees and you're still cold... put a sweater on!

[james danny]

just take a adding machine and subtract 5-8 degrees

[Bob Denman]

...But don't forget to carry the 7...

Sorry to resurect an old thread... but my 2013 RT ambient temperature is way off all of the time. It reads a minimum of 10 degrees to high. Riding at noon today, the temp is 78*. Spyder reads 109 after being parked in the shade, dropped to 100 at 50 mph down the road.

It's off this far when i back out of the garage in the morning too... anyone else? I have about 400 miles on it.

The sensor could be bad, or the dealer could have failed to properly mount the sensor during prep. I'd see the dealer and insist that it be corrected. They all tend to read high, especially after parking in the sun or after a hot restart, but yours is more than average. There is a test procedure in the shop manual

Thanks. I plan on taking it down for the 600-1000 mile service... I'll have them look at it then.

My 2012 reads AT LEAST 8-10 degrees high all the time, sometimes 30 degrees high after sitting in the shade. The BRP tech says this is normal. Seems like a design flaw to me. How am I suppose to have any confidence in all the computerization when the temperature gage is this far off.

You first post. Welcome!!

[Bob Ledford]

On a good day the one I have is either 10 degrees to hot or cold. But always +/- 2 degrees when I take it in to gripe about it. So I just gave up on itx
