Hall Speed Sensor W124 broken
 

hi,
my cruise control isn't working and i assume CC wouldn't work just because the Hall Speed Sensor is broken, i guess....
well maybe you could assist me how to determine the Hall Speed sensor is broken or not.
I've search within this forum and couldn't find the answer :(

thanks

Hall Sensor?
 

It is most likely your Cruise Control Amplifier. There are many posts on this subject. Good luck.

well, my amp is doing great there's nothing with it.....

Just curious. How do you know that?

ehmm... because i removed my old instrument cluster with the newest one... and i didnt realize that my old instrument cluster has a speed sensor right behind the odometer, unfortunately the new one hasnt......
after couple of months, just realize that CC requires speed sensor :(
before i replaced with the new cluster CC works fine.....

well my original cluster has been sold, a week after i installed the new one ,including the speed sensor :(

then i found the aftermarket speed sensor, but i dont know the sensor is working or not......

well, not many cars have a CC in my country, only import car has it :(

well my CC is working now ..... :) thanks all

so how did you make it work? did you get a new sensor?

..and the remedy was ?????

Nice to post results for the next guy.

sort of... :)
actually just borrowed it....
gonna test it tomorrow, on high way :D:D:D

thanks guys...

the remedy was.... the speed sensor, finally i could use it..... again, after years without CC :)

oh.... so relief....:D:D:D

Very Good.

Another overlooked CC problem can arise from unequal tire size or PSI, but that usually shows up as CC cut-out as speed increases.

that's another solution for CC :book::book::book:..... great forum.....:D:D:D

Never thought, my CC on 260E 86 works properly, mainly for amp
