Gear Position Sensor issue (check engine error 25)

Hi,

I have a stock 2017 Versys-X 300. I seem to be having an issue with the gear position sensor. A couple of months ago I had the check engine light come on, the error read 25 which from my understanding is the gear position sensor. So I ordered a new sensor and replaced it. The check engine light went away after riding it for a few miles. Unfortunately, the check engine light with the same error code has returned after about 100miles of riding.

Has anyone had issues with this? I don't know anything about gear position sensors, aside from the fact they tell you what gear you're in lol. So I guess my question is, could this be caused by a larger issues, such as an issue with the transmission or electronics etc.? The bike feels to be functioning fine, shifting feels normal. I'm just getting the check engine light and the dash only shows when I'm in Neutral. When I'm in gear (1-6), I just get 2 flashing lines next to each other. Also, is it normal for a little bit of oil to be where the sensor goes? When I removed the sensor I saw there were traces of oil around the walls of where the sensor sits.

I appreciate any information you have. Thanks!

Thanks for the response. If I read the thread correctly they're having that issue due to changing the sprocket size etc.? My bike is stock. I haven't done any mods.

I've added pictures. The first one is with the sensor out. Is it normal for there to be oil where the sensor sits (as seen in the first image)? The second and third picture just show what it looks like when in gear, you can see where it should say 1 gear it has the lines flashing. I'm thinking of buying another sensor, maybe I just got a bad one that died quickly. But thought I'd see if anyone knew if there could be something else causing this than just the 2 sensors I had going bad, since they're over $100 each lol. Thanks.

ECU reset??

My little knowledge on this I recall something about resetting / clearing the memory of the ECU . I do not have access to the service manual unfortunately, so you may need to wait from someone that is familiar with this.

Hi. First off, the fault that I encountered by changing the gearing did not kill the neutral light, which I see in your photo is not lit. Otherwise your symptoms are the same as a gearing change.

Can you be absolutely positive that your bike is geared OEM? OEM is 14/46. Please physically check this.

My issue caused two fault codes - not just one.
24 Rear wheel rotation sensor malfunction, wiring open or short.
25 Gear position sensor malfunction, wiring open or short.

There are two ways to clear the 24/25 fault codes. One is by the dealers OBD reader and the other is a manual reset which is a PIA.

How To Read Service Codes:
Turn on ignition.
Push the upper meter button to display the odometer.
Push the upper meter button and Iower meter button for more than 2 seconds.
The service code is displayed on the LCD instead of odometer. Multiple codes will be displayed in a sequence with the interval of 2 seconds.
Turn on/turn off the ignition to return the display to the normal operation mode.

How To Erase Service Codes:
Turn on the ignition and start the engine.
Keep the idling more than 30 seconds.
Run the bike for more than 5 minutes at a speed of 25 mph or more.
Stop. Turn the ignition switch off.
Repeat the above procedures 3 times.

If you do find it to be a gearing issue this is what I found.
I had the dealer change my bike from 14/46 to 15/46 pre-delivery as I had ridden the demo and realised just how short geared it was.
I then changed to 15/42 as it needed to be even higher. The result was too high and so I reverted to 14/42 (incidentally the OEM gearing for the Ninja 300).
Perfect!
On resetting the fault light and no gear indicator the issue was back during the first ride.
Therefore 15/46 is no problem, where 14/42 causes the fault. 14/42 is a slightly higher gearing than 15/46 and better gearing all round IMHO.
14/43 may be a safe option, a tad higher than 15/46.

Just an afterthought. You have replaced the sensor and found that was not the problem. A third sensor would surely be the same.

My dash always faults to the two horizontal lines. Why a second image with all blank? What causes the dash area to be completely blank.

As the sensor bolts onto the crankcase I would assume it normal to have oil there.

Is your bike ABS, or Non-ABS?
