so my speedometer no longer works.
i just put the engine back in the car after a rebuild,
and now it doesnt work.(worked before the motor was pulled)
i had a gsr swap before aswell.
ive tried a new vss,
a new cluster,
running a signal wire to the ecu/vss/cluster,
ive cleaned the pins connecting to the vss,
ive checked all of my fuses,
and still nothing.

i did remove the cruise control module from under
the driver side of the dash if that has anything to do with it,
but i cant find it to throw it back in for troubleshooting.

any help is appreciated!
thanks.

Do you have CEL code 17?

sskracing

no, no cel at all.

Former User

Does the CEL work?

sskracing

yeah cel works fine.
when you put the car in acc. the
cel cuts on and off after the fuel system primes,
and never comes back on.

If the wire running from the VSS to the cluster does not have an open, then the speedo is probably bad.

sskracing

i guess i could try another vss,
it would be the 3rd one.

Former User

A bad VSS would generally throw code 17. Your problem more likely lies with the speedo, assuming you have correctly checked the wire.

sskracing

well i ran a new wire from pin b2(behind the cluster)
to the yellow/white on the vss,
and still nothing.

Speedo

sskracing

okay but i installed the stock cluster in and still didnt work.
(ive been running a jdm eg8 cluster for the longest time
and had no problems)

Former User

Check the terminal for the VSS Yel/Blu wire in the cluster connector.

sskracing

Well everything is good behind the cluster.
Im going to test the vss later on today
and see if it works.

Former User

You've already replaced the VSS three times. What are the chances that all are bad? In addition, a bad VSS would typically throw code 17. Be a detective and don't ignore obvious clues. If the VSS and speedo/cluster are good, then logic dictates that there is a bad wire or connector.
