2016 R1200GS Fault code 0x21FD31 and 32 Camshaft sensor
« on: April 30, 2024, 04:51:01 PM »
I have a 2016 R1200GS that went into "Engine in emergency operation mode" (Yellow triangle and engine icon displayed).  The bike was running erratically (quit running often, running on one cylinder, low power).

GS-911 showed fault code 0x21FD31 and 32.  I couldn't find any posts in this forum on this fault code.  Only a couple of Youtubes on replacing the camshaft sensor.  I have the Haynes Service Manual on this bike.  Is describes how to replace the sensor, but not how to test it.
My question is does anyone know how to test the sensor (voltage or resistance)? Or any other solutions to this fault code.  I really don't like to just through parts at a fault code.

Hello
21FD31
Check wiring, wiring harness and plug connector to camshaft sensor.
Check wiring harness plug connector to DME
Check camshaft sensor.
Remove camshaft sensor and check for contamination (metal abrasion).
Check sensor gap to camshaft.

21FD32
Here is the same error description

Emergency operation with limited vehicle dynamics.
Significantly reduced maximum engine speed.

Schönen Tag

Thanks for the quick reply!
I did go to bmwfault page but didn't have an error code that was valid.  All I had was the GS-911 fault code, where do I get the bmw error codes from?
What is the gap for camshaft position sensor?

thanks

When you put in code 0x21FD31 you have to drop the 0x for it to generate a Hex code.
