hey guys (so my speedometer went out on me today while driving (94GC8).. my RMP side is working fine and so is my fuel side. the speed and odometer is not getting any reading. my question is, is it a bad speed sensor or is it the speedometer it self?? and is there a way to test out which one is bad? thanks in advance

 

The cable probably just needs pushed back in.

 

i just went drove for like about 5 miles out...and check engine light came on....can it cause the cel to come on?

 

Yes, ecu will not be getting a speed signal, so cel and limp mode.

 

hmm do you think it's safe to drive in limp mode?? i have a friend that lives about an hour away, and i usually cruise about 110 to 120kph.. oh and any ideas where i can find some speed sensor for a 94 GC8 EJ20? thanks for the help!
