Odometer is not correct

I bought a 2000 Itaska Horizon that is in absolutely Great condition. Thought it had 28,000 miles on it when I got it. Have had it about a year. We are taking our first long trip with it at this time. Was curious what the mileage was so kept track of the mileage and to my surprise great mileage...until I compared it or map quest mileage. Still happy with mileage, but odometer appears to be off by about 45%. When looking at the kilometers they are off also. Has anyone experience with this?

Are the tires a different size than what it came with?

Tires might account for 5% diff--first thought was that 45% sounded a lot like kilometers vs miles until you said you checked both....sounds like a faulty speedo now....

The map quest mileage could very well be off by a good % too.

45%? Boy oh boy either you were getting great computed gas mileage or really lousy gas mileage depending on which way the error went.

Check the odometer again with a known distance like on the interstates. The mileage markers are pretty accurate.

BTW, we went to a Fleetwood Discovery Rally in Kennewick several years ago. That sure was a beautiful part of this country.

Hi Snowmobile1 you might use a GPS or a smart phone there are a lot of good apps for free that work good to check the speedo on your rig. Mine was off about 5 mph so I took it to a Cummins repair shop a they reprogrammed my Trans for about $45.00. Now it is right on with the GPS. Hope this helps.

All Interstate roads and many others have mile marker post.

Check your odometer with 10 miles of them to see how far it is off.

After I put a bigger size tire on my MH, and having Cummins change the RPM it still only registers 9.9 every 10 mile markers.

So when figuring MPG I have to add 1 extra mile for every 100 on the odometer.

I did check it with a GPS today. Odometer 268 and GPS 140. Lots of extra miles on coach. But great mileage..ha,ha. You guys sent me in the right track. Electronics in transmission can be reprogrammed. Thanks

140 miles converts to 225kilometers, close--, possible??..

Converter here: Miles to Kilometers conversion

yet that is what I though at first too. Except The kilometer gauges off by the same amount. Must be a programming problem

Depending on how long that vehicle has had that error you certainly has less miles on it than the 28,000 you thought you had.

My grand father bought a used 74 Chrysler New Yorker in 77. I went with him on the test drive. He immediately said this speedometer is off and it reading much too fast. He didn't graduate H.S., But he had been a truck driver in the 40s and 50s. He knew right then the miles were less then what it showed and there car was in very good shape.
He bought it. and found it would put 40 extra miles going to Columbus Ohio and back (290 miles on the odometer when the distance was 250).
I loved that car, 2 door nutmeg color. Really nice. when I was 15 he traded it in on a 1979 Dodge Omni because of the gas prices.

With the odometer being 45% off... it's strange that the speedometer wasn't off by that much too.
