Speed Sensor Problem '90 NA 2+2
Hmm, having an issue where my '90 NA speedo drops to 0. I have replaced the speed sensor but no go. Anyone else had a similar problem.
oh, it does it very rarely but when it does it makes for some pretty scary corners!!!

Re: Speed Sensor Problem '90 NA 2+2
Update: After taking the car into Nissan here in Calgary I am still no further ahead than I was.
They have diagnosed (very quickly) that it is the "Speedo Head". Does anyone have a wiring diagram better than the basic Chilton Books or shade tree mechanic style manuals and could offer advice?

Re: Speed Sensor Problem '90 NA 2+2
Just a note for anyone that has a problem with their speed sensor (off the transmission, 5speed I can't speak to the AUTO)
A failing speed sensor on the transmission if not replaced promptly, will cause an additional failure in your Speedo Head according to Nissan.
Certain failures of the sensor cause a voltage overload to be fired through the circuit and causes damage to the Speedo Head transducer (Behind the speedo). Once this happens, there is a grounding that occurrs intermittently causing the speedo needle to drop to 0, your cruz control stops working and the variable speed steering is also affected.
It is a whole lot cheaper believe me to fix that sensor right away than have to also buy this $450(CAD) transducer from Nissan once it also becomes damaged.
Just an FYI!
