Vehicle Speed Sensor Help Needed

[jbain2]

I would think you could test continuity from the connector at the VSS to the ECU and then again from there to the speedometer. You’d obviously need the wiring diagrams (let me know if you do). You can just use the standard continuity reading on your multimeter where it produces a sound when it gets continuity in addition to the ohm readout.

I guess in theory if you could get a boroscope in the hole where the VSS is and put the car in gear on stands or a lift you might be able to see the tone ring but it may be rotating too fast?

Thanks for the response!

Woof, I don’t want to dig into the harness. I do have the wiring diagrams, I think. Thank you for the offer, I’ll hit you up if I can’t find what I need.

I like your idea of a borescope down the VSS hole. Maybe I’ll try it with the vehicle off and spin the CV axle by hand to see what’s going on.
