Hi all - does anyone have a speed sensor for my Z31 N/A auto 1987?

Tested the voltage as per FSM at the auto control module - reads as 4.75vwith no change when rolling the car backwards and forwards - so I guess the sensor is faulty.

Not getting any reading from the speedo and am unable to use overdrive and cruise - which I guess are all connected.

Doesn't seem to be clocking up any miles either - is this likely to be linked?

Thanks

 

Must be that time of year as mines on the blink!
I've got two spares and guess what no joy when swopped!
I've checked the wiring using a 1.5 v battery from the plug by the
RH inner strut to the dash and the wiring is fine. I'll take a punt and by one from the US

 

Let me know if you locate a supply at a reasonable cost! Came across one for ~$150 plus $700 shipping - lol

 

Is it the one that is attached to the gearbox?
