87 4x4 truck,22re, automatic trans. I have a code for #1 speed sensor faulty in the combination meter, and I cant find any info on what it sends a signal for?
I can hear something spinning in the cluster when I'm driving, and was curious of how detailed it is removing it, and what function it performs.
Thanks in advance for any help.

 

Welcome!!..this is a addictive forum..search "speed sensor".....lots of info on that....then report back

 

Searched, and found nothing I was looking for. Found out it was a part of the speedo head, and toyota lists as discontinued.Simple question " does it have anything to do with shifting?"
Does anyone sell this sensor, and how much of a pain is it to replace?

Copy and paste this address. Page 7 explains how the speed sensors work. I have never had the speedometer apart so I do not know how difficult it is to fix.
Hope this helps.

 

Thankyou! That piece of info was informative. Does anyone sell this sensor? Or even the whole speedo assembly. I have a local toy scarpyard , but they are proud of discontinued parts.
