140 Speedometer sensor
 

94 Sclass 140
I understand there is a speedometer sensor somewhere near the right front wheel of a 140. Need to know exactly where?

Speedo signal is a processed signal from the ABS traction system...Is that light on??

No the light is not on but sometimes when I hit a bump with my right front tire the speedo will drop to zero and stay there. I can restore it by hitting another bump with the right front tire so I think there might be something loose.What mite it be?

The ABS signal is generated by the LEFT front wheel speed sensor.

How do I locate that sensor? Where exactly is is?

Is this good enough?;

If the ABS lamp is not ON...then the wheel speed sensor is GOOD!

You are heading in the wrong direction. Unless the ABS lamp comes on DON"T blame a wheel speed sensor.

then why sometimes if i hit a bump the speedo goes to zero and by hitting a bump again I can restart it.
PS sometimes when I start my car the abs light stays on and by restarting it goes off.
