Speed Accuracy...
The Yaris is said to have two different stock wheel/tire combo, the 175/65/R14s and 185/60/R15s. Currently I have 185/60/R15s, and my speedometer reading is off by 2MPH, where it reads 60MPH, when I'm actually going 62MPH. So I believe my car is dialed for the 175/65/R14 combo. It's kind of bothering me and want it fixed. Am I the only one having this issue? I don't want to go with smaller tires because currently the tire size I have fill my wheel well nicely. Is there a part number difference for the speed sensor that goes in the transmission?

Hmm, my speedometer reads faster that the actual speed.
Interestingly, If I take the output from the OBD port, it agrees with GPS speed. I wonder if anyone knows if it is possible to physically open the speedometer and adjust it?

With my '09 HB The speedometer is dead on
This is according to all those solar powered speed read outs that a lot of towns use. When a readout says 30 MPH (in a 30 MPH zone) that is exactly what my speedometer says also. This is with 185/60/R15s tires as this is the size that came with it |

Eureka!!!
I discovered that there ARE two different part numbers for the speedometer driven gear sun-assembly!!!
One specifically states 185/60R15, I’m going to order it and install and see if that fixes my speed difference issue that’s bee driving me nuts for years!!! |

Is there a special tool to remove the speed sensor that's in the manual transmission? I couldn't get mine off to try and replace the gear sub-assembly. And yes, I removed the bolt that was holding it.

it should be sealed by an o ring, sometimes they fuse themselves to the case, just keep struggling, swearing, and fucking up your hands until its out lol
