[ExplodingCake]

Simple , replace the VSS

[jhondayaaj]

is your speedo working?

[92turboaccord]

Simple , replace the VSS

already did

[92turboaccord]

is your speedo working?

no its not

[92turboaccord]

4-Vehicle Speed Sensor open or shorted - No signal from speedometer

so i messed with the wiring and figured out that the cause of this code was a bad ground caused by a broken/bent ground pin

hope this helps someone else

[92turboaccord]

so once again code 4.... changed the vss and didnt work from what i know it is a good vss.
so another question i would have can you change the internals to make a good one?
and is there a way to check it

[92accordcb7ex]

i am having this same problem my speedometer isnt working and i have a blinking d4 light and the code is for the vss as well and i replaced it and it still isnt working. what wires could i check to see if they are bad.

[92turboaccord]

im in the same boat i know it only has 3 wires black orange yellow and i have power and ground from the correct colors..
i even went as far as to change the speedo but still nothing

[92turboaccord]

so i checked the orange wire on the cluster and im supposed to have power when the wheels spin right?

Sounds like to me its time to break out the volt meter. I dont know if its possible but I have heard the gear inside the little VSS housing can break and you will have to break open the tranny to replace the gear. I am sure you just have a simple wiring issue.

[92turboaccord]

yea i did and nothing... im gonna check the wires ar the vss... does anyone know what reading i should get??

[wed3k]

continuity between black and body ground

with ignition switch ON, battery voltage at yellow wire

5v reference voltage should be at orange terminal and body ground

[92turboaccord]

so i have 12+ volts at both yellow and orange wires
