My 2011, 2.5L, automatic Camry's speedometer reading is off by almost 3 mph. I noticed this after the city I live in installed a couple of those solar powered radar guns/signs. My other vehicle reads exactly whatever the the radar gun/sign reports. Curiosity got the best of me, so I connected my Bluedriver to my Camry & checked the speed reported by the scan tool against the speed reported by my Camry's speedometer. The Bluedriver reports the Camry's speed as being off by the same amount as the radar guns/signs, 3mph. Car drives fine, no codes, so what gives?
Well they're often a little bit off. All mine are my Lexus is a bit high and the matrix is a bit low. They're never perfect. But you could try a new sending unit on a transmission
Thank you, Scotty.
I forgot to include in initial post the tire/wheel sizes were original, which is pertinent info.
My speedometer reads on the high side, 40mph should read 37mph, but I'll just leave my Camry "as is" because it does not create a driveability problem. Thanks again!
