Honda Repair Questions? Ask a Mechanic for Answers ASAP
If the contact cleaner didnt take care of it, you will most likely need to replace the sensor. Especially if it doesnt work at all now, after the cleaning.
Like i mentioned in our last conversation, there is still a possibility the speedometer/odometer itself is at fault, but the sensor is MUCH more common to fail.
The only sure fire way to tell would require a special scan tool that the dealer has. I know you want to repair this yourself, so about all you can do is replace the sensor.
If you have further questions on this, please feel free to reply.
Its a bit pricey at $125 but most likely its the faulty culprit, however there is still a chance of the speedometer itself, but without a scan tool you wont be able to tell. The odometer and speedometer both work off the speed sensor.
