i just picked up a 94 ej1 and somtimes the speedo goes crazy like when im at a light it will say im going 80 or somtimes it will just flat out not work. does this sound like the vehicle speed sensor and if so, does anyone have any pics of where it is located?

 

no CEL?

speedo head is dying.

 

what do you mean speedo head is dying? i am experiencing the same problem, i have swapped out the cluster, but does the same thing

 

Check your VSS plug to make sure there isnt any fluid pooled in it. Believe it or not, thru swaps, or just time in general, the way the plug sits, it can pool fluids in the plug, which will kill the circut, causing the VSS to work sometimes or not at all. Take it out, drain it, let it dry and you should be set. Ive seen this case happen a few times before on HT

Its located on the topside of the tranny, back near the differential, by the starter. You can basically start at your throttle body, and go straight down, its in that area. It can be removed by its 10mm bolt(s).

 

VSS units have a white plastic "shield" which sometimes can get doubled up.

This causes a bad connection, but it will cause the ECU to throw a CEL #17 due to now VSS pulse.

If ECU is getting VSS pulse from tranny, but jumpy speedo, the speedo head in the cluster is dieing.

99% of all VSS issues end up with a CEL 17 and a dirty connection at the tranny, mostly due to road salt in the winter months.

Yeah, but he's saying no CEL + he swapped clusters and it's doing it with the second cluster.

 

mine does it too, still does new speed sensor and still does. Although.. My wires was cut. I soldier them together and yet still does...

 

i was about to post the same problem when i came across this.. im in for some more info

 

ok i think have narrowed it down. when i hit the gauge cluster it works. then randomly stops so maybe its a bad connection

 

Yup mine is doing the same thing. Most likely its a short... earlier today it did it so when i came up the next light i restarted the car and worked again, giving me the idea something is loose. Keep us posted if some other reason comes up.

 

mines doing the same thing too... sometimes it works and sometimes it doesnt...
