1994 accord speedo problem

If the speedometer works, then the assembly is bad. If neither speedo or odometer work, bad speed sensors are a common failure.

a real DTC code.
17 , 94 Accord
the means VSS is dead, vehical speed sensor (miles per hour)
so , that begs the question is the speedometer dead or odometer
dead or acting funny IN ANY WAY?
is this an A/T Car or M/T car, both have VSS, so... cant answer.
Auto or stick, ill pretend, AUTO.
VSS moves all over the place, in all cars. all models and all years.
on this car, its odd.
quote FSM:
Accords and Preludes use an external sensor mounted on top of the power steering speed sensor in the engine compartment. The power steering speed sensor is gear-driven and controls the steering boost in relation to the speed of the vehicle. An electric pulser unit is mounted on top of this unit and is coupled to it by a small shaft. The motion from the lower unit is transferred to the upper unit; the resultant electrical signal is sent to the appropriate control units.

most cars old use the speedometer VSS sensor inside
on newer cars 1996 (on avg) the sensor is on the tail shaft. and in speedo.
on very new cars there are 3 VSS.... (dont ask)

on my 96 car, the tranny VSS can fail and then FALL back to the
SPEEDO head. and tranny still shifts but is funky,
the FSM covers all this, i recommend getting one, to understand
how it all works.

your car has and electronic speedometer
the VSS orange wire , sends speed data to the PCM, TCM, cruise.
the PCM then sets the speedo dial, and uses this info to run TCM
controls to the transmission.
your orange wire signal is dead or flaky.

Remove the speedo cable and examine for damage ie rounding of tip or broken teeth on gear. Otherwise the speedo itself should be taken to a instrument repair shop for repair.

The speedo head or cluster is the part that houses the speedometer and tach, etc. now it may be the speedo cable that comes from the transmission to the speedo head that has broken. If so replace the cable and your back in business. If it is the head you can get them from your local recycle yard.

If all the connection and power supplies to instrument cluster are ok,I suspect that the speedometer or instrument cluster is faulty but before you replace it, make sure the gear inside the transmission that drives the VSS is in good.

I had a similar problem a few months ago. I changed the speedometer sensor as well as the instrument cluster with no result. Finally I decided to take out my ECU. As soon as I took it apart, I noticed a burnt node. Replaced the ECU and the speedo worked fine. You might try this if tinkering with your cluster doesn't work.

there are two reasonable explanations for this:
vehicle speed sensor is faulty and speedo cable is faulty and bulbs for illumination or illumination switch is faulty but I would lean with all of those its your gauge cluster
or gauge cluster itself has gone out both of these arent that expensive heres some places where you can get cheap replacements

try resetting the trip meter. if that doesn't work you need to replace the speedometer head. i have seen this problem a lot especially when the 94 accord was new and replaced a few speedometer heads.

about 240.00 according to the volvo dr. ,fountain vally ,ca. An elect. part behind the speedo. is the problem . My 91 940 speedo stops working at 45 mph. thats what they told me. good luck,pete.

speed sensor servo common on hondas weve done many due to the d4 light and eratic speedo
