Correcting speedo error
A GPS is as accurate at calculating your vehicle speed as is a 'certified'
speedo in a police car. So when the speedometer in my 2006 Liberty was
registering 107 kph when the GPS was showing 120 kph, I mentioned this at my
next service interval. The mechanic came up with a relatively easy fix. He
re-programmed the computer to make it think I had different sized tires on the
car. He got it dead on. However, the odometer still registers less kilometers
than the GPS records. I have verified the GPS odometer with the markers along
the highway.
Can anyone confirm that electronically altering the speedometer reading would
not necessarily change the odometer as well?
Thanks

Of course it would alter the odometer too, it's part of the speedometer.
Maybe it would be a better idea to find the real problem.

Re: Correcting speedo error
That would be odd, but there 'could' be two different calibrations in
the computer program.
I doubt anyone here has a factory manual for a Liberty to tell you for sure.
