Crankshaft Position Sensor location??

[tho9504]

Hello, i am new to this forum and really wanted some help. I just purchased a 2012 FZ6R. i wanted to install a gear indicator (Healtech GiPro X y-01). I am so confused with the wiring. i think i am ok with the +12v connection and the speed sensor (3 pole under the gas tank). My confusion/problem is where the Crankshadt Position sensor is? Does anyone have a picture of it? i see so many different connectors, i dont want to take any risk. Any help is greatly appreciated.

Thanks...

This is the wire that come off the RH side on the engine. (Cover line up with the crank... not the clutch)

It's very hidden and only dark gray on the crank side of the connector. It's hidden by plastic/rubber sheathing. When tank is lifted look under frame almost dead center of bike almost under air cleaner. I tapped mine there. You can trace it back to the crank and tap somewhere else. Also don't use brown wire for power. It's for the brake and only activates when brake lever is squeezed. There's a yellow wire in same area which is switched by key and always on with key on. I have basic instructions somewhere on here, but no pics.

Thanks for the reply.. I will check it out once i get home from work. For the +12v wire, i was actually going to tap one of the wires from my flush mounted turn signal attached to my left fairing. I am hoping that has power all the time when ignition is turned on and not only when i use the turn signals. The speed sensor i believe is plug and play with the GiPro x. I will lift up the tank today and look for it again with the right side of the fairing removed. Does the connector have a specific color/shape/prong or is it similiar to all the other connectors there? i tried to look in the service manual but they give you a drawn diagram which is not much helpful for me. I dont know how to read wiring diagrams. i wish they supplied a actual picture on the manual like they do for car service manuals.

Just curious, Is the wire more visible/reachable near the crank side on the right side of the bike, without lifting the tank?

Thanks for all your help...

Should have to splice 2 wires (12v power and crankshaft position sensor) unless you have a different model gipro. I spliced a yellow under tank near the harness you have to connect to and the light gray crank wire which took a while to find. If this is the setup you have then look just under frame under back of air cleaner assembly. You have to move plastic covers around to find it. Only light gray on one side of the harness.

Thanks for quick response. Do you have the GiPro X GPX Y-01 setup? There seems to be a harness to connect the speed sensor, so no need to wiretap the speed sensor. Per instruction this what it says:

1) Locate the Speed Sensor coupler.
The Speed Sensor is usually located on the top of the gearbox and reads the
revolution of the countershaft.

2) After separating the Speed Sensor coupler, plug in both the male and female
3-pole GIpro harness connectors. Make sure the connectors are fully seated.


3)Find the 2-pole natural (or black) color plug of the Crankshaft position sensor
(Pickup coil). It has two wires coming from the crankcase: one is Gray, the other is
usually Black/Blue - check the colors at both sides of the plug (if in doubt, do a
temporary connection e.g. by using a thin needle to backprobe the connector pin).
The 2-pole connector is usually under the fuel tank

4) Connect the GIpro Black/Green wire to the Gray wire, using the Red wire tap
connector supplied.

OK, so i finally took off the right side fairings and took some pics. Can you confirm if this is the camshaft sensor?

Is this the crankshaft? I saw this wire/sensor attached to it - circled in red

 

[tho9504]

I saw a connector (I am hoping it's the crankshaft sensor) after removing the right side fairings. it's was bundled along with couple other connectors all inside a rubber boot. after looking at the connector, one of the connectors have a dark grey and light gray wire on one side trailing from the crankshaft. on the other side of the sensor are "grey wire with gold dot" and a "black wire with gold dot and blue strip". If this is the crankshaft sensor, do I wiretap the grey wire with the gold dot on the other side of the sensor or the side where the wires came from (crankshaft) which is light grey and dark grey wires.

I tapped the light grey, not sure if the others would work.

Yes, there is no speed sensor splice, just 12v power and crankshaft position.

When you go to program the gear indicator you may want to do it on stands or make sure you have plenty of room before you need to stop. The first time I took her out after installing it started to program automatically. Just need to hold the revs for a few seconds in each gear until it completes the programming for that gear. If you stop it assumes you only have however many gears you programmed before you stopped. I only got to 4th gear. It's easy to reset though. With the bike off you turn the key on until the gear countdown hits between 3-5 and then shut key off. You have to do it like 6 times and it will change back to "L" for learning mode. Second time around I did it on my stands so I didn't have to worry about stopping.

Thanks Scott for all your help. I guess the "Light Grey" wire you mentioned is the one from the crankcase going to the connector which has "light grey" and "dark grey" wires going into the sensor connector. I will tap the light grey wire. Thanks for all your help...

Yes, that's the one.

OK, this could be a dumb question but I am a little concerned, so i'll ask. The crankshaft sensor and a couple of other connectors are bundled inside a rubber casing. But that rubber is resting on top of engine metal piece. My concern is when I engine is running, wouldn't that burn the wires? Is this how your setup is also? The metal piece it's resting on is right behind the oil drain plug in the middle of the bike. I attached a picture to show what I am talking about. please tell me that metal piece is really some heat shield. ... the last thing I want is toasting up all the wires that are tucked inside that rubber casing.

 

[tho9504]

not sure if the picture got attached before. it's 67.5kb size

 

[tho9504]

*Correction*

I did NOT mean to say oil drain plug, what i meant was Oil fill.

Yup that's it. Try to get everything back in the rubber. It's more for water protection then heat. Not a hot area as far as I know. Can always use electrical tape too.

 

[tho9504]

Thanks Scott for all you help. Just for my peace of mind, i think i am going to get some heatshield tape from Amazon and wrap around the connector wires and then tuck them in the rubber boot.

I ordered the clutch/brake lever also which should arrive tomorrow. I just picked up the bike last saturday and i had to ride it on the highway for 40 minutes. i moved up from a CBR250R so i need some time to get used to the FZ6R clutch which i felt engaged all the way at the end of the release. i am going to change the levers out with adjustable levers.
