I have a 92 wagon. When the speedo acts up the car runs different.
Is this a clue that suggests that the sender is bad or does the speed signal go to the gauge cluster then to the engine computer.
I am hoping the signal goes to the computer dirctly from the speed sensor.
Another clue is that when it starts acting up, I can make the speedo work intermitently when I am on and off the throtle abruptly. This action only involves the the slop in the diff, not the gauge cluster.
It is a California car. No corrosion at the sensor plug. I took it off and cleaned it anyway, made no difference.
I had a very leaky diff that has since been repaired. Could something be damaged or goofy from lack of diff oil?
Sure do hope it is the sensor not the gauge.
