URGENT !! Need Help for 2016 R1200gs lc camshalf sensor
« on: August 02, 2019, 01:47:19 PM »
Hi all,

Too bad for my bike again. I found out via GS 911 that my bike got another fault code appear.

21FD31 camshalf sensor input signal. No signal edge detected.

After i pull out the camshalf sensor that link at the boxer there. I clean it up and install back again. Then more worst, at GS911 appear a new fault code 21FD32.

Anyone can give me some detail on this ?

Please..

Tan

Hi Tan,

The new error code description is Camshaft, inlet, invalid position

I don't have much more mechanical suggestions, however I'm sure the always-helpful users on the forum will be able to give you some pointers

Hello Tan
Which dirt on the sensor?
Possibly metallic residues, the sensor is magnetic. If so, I would check camshafts and valve actuation for damage.

Fault code 21FD32 requires checking the valve timing, camshafts and chains

Here is a bit of info for you Tan on the 21FD32 code

DME (BMSX ?)detects an incorrect number or signals from the camshaft sensor.
Too many or too few camshaft signals are present within several camshaft rotations.
The number or sequence of the camshaft signals is implausible.

Check wiring, wiring harness and plug connector to camshaft sensor.
Check plug connector wiring harness to the DME.
Check camshaft sensor.
Remove camshaft sensor and check for contamination (metal abrasion).
Check sensor gap to camshaft.

The difference between the first code (21FD31) is The DME detects no signal from camshaft sensor.
No camshaft signal is present within several crankshaft revolutions. So you may have improved it with the first cleaning, I would try again and check the other things also.

You may need to check you cam timing.  These cam go out of sync over time and need to be loosened, adjusted correctly and tightened again.  The timing arm is also attached to the lower cam with a pinch bolt that may be loose.
