Gear Position Sensor - Removal / Installation (Video)

[jasonb]

Hi all,

Had to take my Trophy in to Triumph about 11 months ago as i had issues, which they say were caused by a dirty gear sensor position, they cleaned it, charged the warranty £80 for the pleasure and to be fair, didnt have any other issues, until about 3 weeks ago.

After a lay of the bike of a couple of months, due to lock-down, i took the bike out and refused to go from 1st - 2nd gear, pulled over and with a struggle managed to get her in to 2nd, 3rd and back down.  So carried on, first set of lights, coming to a stop went down to third, refused to go from 3rd in to 2nd, so pulled off in third and continued.  Got to work, did a couple of hours, then came home, no issues at all.  Thought nothing about it, then couple of days had the later, again got to first set of lights, refused to go from 3rd in to second.

So thought, cover the old ground first, lets eliminate the sensor (based on what happened a year ago).

This video covers the removal and installation of the gear position sensor, a very easy job, but someone might find it useful.

Another good video, thanks for posting!

Thanks for the video.  One follow up question, what do you actually clean the sensor with?  Your video covered how to remove it, fit the new o-ring (gasket you called it), and re-install.  I don't recall you actually cleaning the sensor.

I'm curious because sometimes I have a hard time downshifting when approaching a traffic signal.

Not sure as I haven't had to clean one yet, but if it is sluggish and hard to turn, perhaps cleaning the disc and under it with brake cleaner until it turns freely would be the ticket.  That's where I would start, anyway.

My gear indicator has stopped working several times.  I could still shift gears with no problem.  The indicator will show first gear no matter which gear I'm in.  This will happen at random in the middle of a ride.  A yellow check engine light comes on and the cruise control stops working.  I've had the gear indicator sensor off and cleaned it but the indicator still acts up.  I can stop and turn off the ignition and restart and things will go back to normal except the check engine light.  I can cancel the error code with the Dealertool or cycle the ignition several times to get rid of the light.   I'm installing a new gear indicator sensor to see if that takes care of the problem for good.  Thanks for the video.

I replaced the gear indicator sensor a couple months ago.  Everything seemed ok until I was riding today.  Once again only first gear was indicated while going though the gears.  Shutting the bike down and restarting fixed the problem.  Now I'm wondering if I have an intermittent electrical problem.

Do you remember how many wires the sensor has?

I kept the old sensor which shows no obvious defects.  There are 4 wires on the plug.
