Inaccurate analog speedometer
Hi all.
I think many of you know that the speedometer readings in some Yaris are not accurate. I suspected this and confirmed with GPS. I found that a speedo reading of 100kmh had actual speed of 90kmh. I was playing around with Techstream and I ran the instrument cluster diagnostic. I found that the speedometer was infact inaccurate and even the tachometer !. Please see these videos I made. In the second video I test the digital meter which IS accurate. Techstream speedometer test on analog meter: https://www.youtube.com/watch?v=5LLENLt-is4 Techstream speedometer test on digital meter: https://www.youtube.com/watch?v=yFrP4yERDzY I think its quite interesting. Anyone else tried this out ? Is there anyway to 'calibrate' the speedometer? |
