Electronic analogue speedos and tachos often can be seen to jump up a bit at switch on - they would usually be resting on the lower needle stop and then jump to zero when the ignition is switched on.
My Mercedes speedo jumped up above zero and I just took it out of the dashboard and removed the pointer and refitted it at zero. My satnav verified the speedo as being acceptably accurate...
The old fashioned cable driven speedos often didn't begin to register until 5 mph.
If it is a digital speedo you will need to approach the dealer about calibration.
Scan the vehicle for fault codes first. Sounds like you need to check the vehicle speed sensor signal into the speedometer. If that is ok then send the speedo head out for repair.
I have a 91 Accord. The speedometer started going wild, 30 mph. 75 mph and I was at a stop finally quit working and the S light came on. I finally changed the speedo sensor and the S light went off...Check engine light was also on, read on a forum that the speedo sensor does more than control your speedometer, maybe that your trans is not getting the info it needs to shift.....
there are shops that can change the mileage in the replacement to match what you have now, the most common cause is the speed sensor on the transmission sending an incorrect signal to the speedometer.
I would suspect you have a faulty electronic speedo head, have the cluster removed and have it sent out for repair of the problem. There is no at home repair procedure for this problem, it takes special equip to repair the speedo.
Try replacing the speedometer sensor, located on the transmission under the car. There will be a few wires going to it with a plug. The speed sensor is a retivly low cost part, and most of the time when it begins to quit it will give irratic readings on the dash.
Hope this helps!
Your speed sensor in your trans. needs to be checked out sounds like its not working or not getting a good signal until its generating enough power and speed to start until it reaches 30 MPH. Check that out sometimes it could just be some dirt on it. It all makes sense the ABS light is on because its not reading the speed of the tires, and the AOD light is on because It has no idea when to shift into overdrive without knowing how fast its going. I sure Hope that Helps You Out, And Thanks, Bear001
