speed sensor

Post by csj »



My girl just got herself a 2006 goldwing trike with lehman conversion. The dealer we bought it from does not have insurance on his bikes, so we were not able to take it for any kind of ride.

After the purchase, while riding it home, found that the speedometer is not working. Cruise control also not working.
Research on this board showed that the speed sensor is the culprit, either not plugged in, or faulty.

My question is, is there an automotive cross P/N that would do the same job. You wouldn't believe what they want for that thing
from honda.

The speed sensor gives input to a couple of systems. The speedo, the cruise control, and probably to the PGM-FI for fuel injecter mapping.

Since 5th gen speedos from 2001-(09 I think) are off by 10%, many owners might install a speedo correcting device. I'd start by verifying that one of those has not been installed. Aftermarket stuff aften fails. Usually such assessory is located under the RF pocket and taps into the speed sensor circute.

If nothing is found, before parts are replaced, testing should be done. Instructions for such can be found in a Service Manual. Your Owner's Manual will direct you here.

Thank you for the thoughts. I have already downloaded the service manual from manualslib.
This is from page 653, or section 20-20.

3. Remove the combination meter (page 20-17).
Place the motorcycle on its center stand, shift the
transmission into neutral and turn the ignition
switch to “ON.”
Measure the voltage between the White/black (+)
and Green (–) wire terminals of the combination
meter 20P black connector.
There should be 0 V to 5 V pulse voltage while
slowly turning the rear wheel by hand.
• If the pulse voltage appears, replace the
meter/gauge assembly (page 20-19).
• If the pulse voltage does not appear, check
for:
– open circuit in the White/black wire
between the combination meter and speed
sensor
– loose or poor contact in the related connectors



I'll soon do more testing and narrow down what is going on.

I called a honda car dealership. The parts counter guy did not
have an idea about a speed sensor part cross from say, a civic.
So, the local honda bike dealer says he wants $270 for the speed sensor.
Ouch.

SENSOR ASSY., SPEED 37700-MCA-A61
Partzilla $110.72
Mr.Cycles $88.40

There are cheaper ones on ebay, but those are probably knockoffs. The ones listed above are real OEM.

I did a word search for 'speed sensor' in the service manual. I found there are three speed sensors.
The front and rear wheel speed sensors are used by the ABS system.

The vehicle speed sensor, mentioned above, 37700-MCA-A61, is the correct one.
It is found on the Partzilla 'cylinder block' fiche.

I was looking at the front wheel speed sensor. Nope. I'll go back to the honda bike
dealer and ask again, this time correct P/N.

If their price is still way too high I'll try ordering from Partzilla, though
might have trouble getting it across the border.

This guy did a video on his F6B, changing the vehicle speed sensor.

I would run from that dealer. No insurance, what a crock. Mrcycle’s price is the best you will find and the wheel sensors are for the ABS system if it has it. Greg is the man, follow his lead and you’ll be fine.
