Guys, 

 

Can anyone help me by referring to a website where I can find the ABS Sensor? 

 

I really need it.

 

Regards

UK dealer may be able to help

To clarify, the battery maybe new but is it fully charged? 

 

I had mine stuck in gear once, it was to do with starting it up on the centre stand and some strange mode being activated.  Fully charged, fully off, off the side stand and started without it being in gear seemed to fix it all.  Possibly a disconnect the battery, charge it out of the bike and reconnect and  a DCT reset once the oil is hot (and the oil needs to be at the correct level) is worth a try before you part with cash.

Thanks for the suggestion.. 

 

Actually it is the Front Wheel Speed Sensor that is not responding to the main System that's why the ABS indicator is not going off neither blinking. And to go from gear 1 to up gears that sensor need to send the correct info to the system. I was looking to the wrong part since yesterday. 

Any help on how to fix it? May be cleaning the sensor, checking the fuses, rebooting the system... things like that instead of start buying parts.

From here what part do you think it is?

If 4 from https://www.fowlersparts.co.uk/parts/5840479/nc750x-abs/front-brake-caliper is 19 there and pointing the correct place?

The system doesn't know why the signal from the sensor is wrong, so before you change the sensor:

 

Check the resistance. An ABS sensor is just 400 yards of very thin wire to make a coil. If its open circuit or zero resistance it's cooked. Something about 10-30 Ohms is a working coil but anything except open of zero can be taken as OK, we don't know what gauge wire Honda used.

 

Set your meter on AC Volts (as a very crude smoothing circuit) and spin the wheel. The sensor will generate about 0.5V AC at 30 rpm wheel speed. If it keeps dropping to zero the toothed polewheel is dinged or the bearings shagged. If it won't generate any voltage the airgap is too big because something in the polewheel, bearings, wheel sort of area has moved. Make sure it isn't just the spacer between fork and wheel that's in wrong.

 

Inspect the faces for marks. The polewheel doing an impression of a milling cutter vibrates the coil to death. 

 

Item 4 is available from Fowlers, Honda and used on the auction site.

Yes it is the Item 4 the tip closer to item 19.

 

I don't know how to do all the thing u mentioned above. kkkk... Will need a proper tech to verify. 

 

But many thanks on the reply.

If you are genuinely in Angola then ordering from fowlers prob isn't on the cards, what Andy said should be doable by any mechanic with some kits, doesn't need to be a bike one

One on that auction site now, second hand obviously.

Didn’t some one have a similar issue and it was because they had removed the front wheel to clean it or something and they had pushed the  sensor back/ damaged the ring  or the wrong way round when it was reassembled . It was a simple fix in the end .
