Sppedometer Pointer

[Wasa]

Hi friends,

This is a problem of my uncle's car. When I was driving it alone, I noticed that its pointer (KATUWA) of speedometer moves without responding to the real speed. Even first gear it shows around 60 kmph and at the top gear it shows around 150 or high. (real speed may be below 70). So I informed him immediately. He said it is a problem and has happened to him too. He said further, it becomes normal occationally speceally when U stop the car & restart. But this time it didnt correct. There was no any abnormality. So I would like to know what the reason if you know please. The car is Carina 212 (1999 as I remember)

Regards..

Replace the speed sensor in the gearbox

Thanks Harshan

But it shifts gears normally (Auto). Theproblem is at the pointer of the speedometer.

I doubt the gear change of this box depends on an input of the speed sensor. If the speed is erratic or shows sudden changes, it could be due to

1. erratic readings of the sensor

2. Loosen connectors of the sensor or gauge cluster

3. Tention of the spring load in the needle (old models) or needle motor (newer models) is got issues.

Simplest is to check the connectors (unlikely since issue gets sorted out when you restart the car) and change the speed sensor. If it doesn't gets sort out the issue, best thing is to change the gauge cluster than spending money and time repairing.

its your sensor we have the same issue on our FB14 - erratic RPM or so the symptoms are...just change or clean it up like harshan suggested
