Thank you for the VIN!

One moment while I pull up your vehicle

Customer: replied 3 months ago.
speedometer and odometer does not work, ive replaced the vss sensor, and im not getting the 10 volts to my vss sensor
Expert:  AMEDEE replied 3 months ago.

The vehicle speed sensor produces an AC signal. It does not receive voltage because it generates it own voltage.

Customer: replied 3 months ago.
what color wire behind the enstrument cluster should I meter with the vehicle in drive and over 3 mph to get my 1.3-6.1 volts ac and the resistants is greater than 5 ohms on grey/black and pink/orange at the vss connecter
Expert:  AMEDEE replied 3 months ago.

It is a gray wire with black stripe.

Customer: replied 3 months ago.
what ohms should I be getting if I messure across the vss sensor because im just getting open
Expert:  AMEDEE replied 3 months ago.

Between 30 and 90 ohms.

its open
Expert:  AMEDEE replied 3 months ago.

It sounds like you have a faulty sensor.

Customer: replied 3 months ago.
ive replaced the sensor and I went to the store and tested new ones and they all came out, opened
Expert:  AMEDEE replied 3 months ago.

I dont think your testing it correctly.

Also, the wires going to and or from the sensor could be open causing this condition.

Customer: replied 3 months ago.
When I messure the resistance from the gray/black wire to ground it is 229 ohms. the pink/orange wire to ground is 50.8 ohms and the resistance between the gray/black and the pink/orange is 279 ohms. I am not getting any AC voltage from the gray/black wire when the vehicle is in gear and running over 3mph.
Expert:  AMEDEE replied 3 months ago.
You have to put both leads on both wires coming from the sensor when checking for an AC signal.
Customer: replied 3 months ago.
it is giving me ac voltage in drive it increases the ac voltage when the rear speed increases but its not 30-90 ac volts
Expert:  AMEDEE replied 3 months ago.

AC voltage is different than ohms
