Ambient Air Temperature Sensor Location
The temp displays a way-lower-than-ambient reading. I'd like to check the connections at the sensor. Where's the sensor located?

Re: Ambient Air Temperature Sensor Location
David, I would guess part 8, an air-temperature sensor, inside the air box.
If you remove the filter, you should be able to get to the connection.

Thanks, Bill.
But I think that's the intake air temperature sensor. There's a separate sensor for ambient air temp - the R12R wiring diagram in the Haynes shows a second sensor for ambient. The text describes its location on the RT and ST, but is silent as to the R.

Re: Ambient Air Temperature Sensor Location
Is it showing degrees C rather than degrees F?

Re: Ambient Air Temperature Sensor Location
Hi David. Mine is a 2012, but it may be the same as your '07. Look behind the headlight. That's where mine is. On the top left as you're sitting on the bike. There is a 1 inch circular recess with a pointed black sensor in the center. Looks like the protruding end of a big odometer cable, but it's black. You'll find it. Getting to the connection will be your quest. Have fun! BTW: mine is often 1 degree optimistic. Never found it to read lower than measured ambient temp. Regards.
Re: Ambient Air Temperature Sensor Location
Nope. All afternoon today (several short trips) it displayed 61.1F, while the air temperature was somewhere in the mid-70s. By the end of the day, the bike had been outside for about three hours, with a lot of in-town riding in traffic, so it was surely warmer than indicated.ammolab wrote:Is it showing degrees C rather than degrees F?

Re: Ambient Air Temperature Sensor Location
Thanks, Clem. I just went out to the garage and looked...and didn't see it. But I have my PathBlazer module ziptied there, and it and its wires impair the view. I'll take a better look tomorrow in the daylight.Clem wrote:Hi David. Mine is a 2012, but it may be the same as your '07. Look behind the headlight. That's where mine is.

Re: Ambient Air Temperature Sensor Location
Looks like this.
Had to shoot through my Z-Tech screen, so it isn't very good.

Re: Ambient Air Temperature Sensor Location
The "outside" air temperature sensor on my R1200R shows at least 5 degrees hotter than actual. My Honda Ridgeline did the same thing, only up to 10 degrees. I asked my motorcycle service department if there was a way to calibrate it, and they deferred. They said I was getting reflected heat off the pavement. I believe them because my Ridgeline was accurate when parked. Like the fuel gauge, I have come to accept it as an estimation.
