1990 Accord speedometer quit-flashing "S" and engine light on

Was passing a vehicle and suddenly my speedometer went to zero. The
"S" for the sport position of transmission is flashing and the check
engine light is on. Is this the speed detect sensor failing? If so
where the heck is the little bugger, I can't find any mention of it in
my Haynes manual. Any help appreciated.

Probably speed sensor. Could also be a bad connector. An Acura
dealer told me I needed a new speedometer after I had brought it in
thinking it needed a new sensor. I wasn't confident in their
diagnosis so I just left with it. They must have at least jiggled the
right connector because I haven't had the problem since and that was
three years ago. (The symptoms were that the speedometer wouldn't
work for the first 3 - 5 miles. Very consistent.)

Maybe it is a connector because sometimes it starts working for a few
minutes or longer. I just need to find out if it is easily accessible
and I might either change it myself or reseat the wires.

As already mentioned, it's often a question of the connector making bad
contact.. The electrical sensor pickup is mounted on and driven by the
same shaft as the power steering speed modulator shown here
http://tinyurl.com/2pcaw as part # 9 and which, as you can see, is mounted
on the top rear of the differential/clutch/torque converter housing. The
P/S modulator is easy to pinpoint by the two P/S fluid hoses attached to
it. The electrical part is shown here http://tinyurl.com/22j2o - there
seem to be two styles of part. If you take the electrical pickup off be
careful not to lose the little "joint" pin.

and for gods sake, dont lose the instrument cluster... it lists at
$10,903.90

surely, thats a typo... right?

 

There's a few of those clangers at that site - even if it's just a decimal
point in the wrong place it still seems a bit steep.

Looks out of whack to me!

Thanks for the info George. I'll check out the connections.

Just a further thought on the electrical connector, in case you're not
familiar with Honda connector "practices". The connector referenced in the
diagram has a metal bracket and where a connector is latched on to a
bracket like that, you usually cannot separate the electrical connection
without first removing the assembly from the bracket.
