Hi I hope some one can help
I have just brought a 2003 Chrysler Grand Voyager Limited 3.3 V6 automatic, and I have one problem, my speedo is 10 mph out, when my speedo is showing 20mph I am really doing 30mph.
I have done a dial reset and fault code find and nothing no codes, could it be the out put speed sensor in my gearbox?
Thanks
Jason

 

Have the wheel and/or tyre sizes been changed at all?

 

There is a very recent post on this very subject of a wrong speedo reading, possibly caused by over-size tyres. The discussion was about whether there was a program change in the micro. to accomm. different sized wheels/tyres as with wagons.

Hi my wheels and tyres are the stock size and match the sticker in the door

 

It's possible though that the previous owner had larger wheels and/or tires and had the speedo recalibrated then simply switched back to the correct size wheel/tire prior to selling? That would be my guess.

 

About 20MPH is about 30 KPH [32.1869] set your readout to show miles not kilometres.
