Title: knock sensor 2 defective
Post by: ihosc on December 17, 2013, 03:52:59 PM
Just purchased a GS911 and ran an autoscan on my 1200R. The report came up with a fault code "10210 knock sensor 2 defective. The fault is not present now." How would you recommend to go about working on this fault? Thanks in advance for the pointers.

pls post a Complete AUTOSCAN, as well as the Freeze frame data

What Stephan ask for  :)

A bit too often the ECU (BMS- or whatever the bikes computer is named) store faults.
Faults that are not important. Reset the faults, start the bike and check once more.
The "Autoscan" show a lot more information, not the least when the the error popped up and for how long there WAS a fault.

Hi Stephan, Thanks for the respond. Below is the autoscan printout. I'm not sure if the freeze frame data is included. By the way I'm aware of my faulty tyre pressure sensor which I'm about to replace. It's only surprise me when I learned this knock sensor defective fault code. Wondering if I should replace them all at once. But before that just want to know if the sensor was really faulty or just data log error..

thanks for this!

is it an R1200R ?

and can you do me a favour, and go into the BMSK and then read fault codes... this will show you the freeze frame data... I want to show you something on it

Hi Stephan,

The bike is R1200R. And below is the readout. Thanks.

OK, let's start from the top.

what we know:
Now from the Fault code history we see the following:
The logistic counter starts at 40 for most codes and then decrements every "cycle" that the fault is not present... Now what exactly a "cycle" is, is unknown... and I suspect it might differ from fault code to fault code... for some it might be ignition cycles for others it might be engine reaching operating temperature etc... (naturally it will reset back to 40 if the fault occurs again)

In either case, I suspect that fault was not repaired... BUT, that still does not mean that something needs to be done...

Next we need to consider the context... this is a knock sensor... it measures vibration.. it might have gotten a hard knock from another source (someone banged a hammer against the engine  - I hope not), or the sensor might even be loose (normally tightened to the engine with a bolt - naturally if it is loos, it will loose it's ability to "feel" the mechanical vibrations...)
On the other hand, it could be a loose or dirty connector... or poor connection...

Check all of the above (mounting, connections - maybe even clean the connections  ...then reset the code... and check it frequently...

Stephan

Hi Stephan, I'm getting the idea now in usage of this GS911 tool. I'm sure there's plenty more to learn. But this is a good start. Thank you. Now just need to google out where the hell is this knock sensor...

Knock sensor is mounted on rear side of each cylinder.Google knock sensor R1200 and you will see how it looks like.Cylinder no.2 is left cylinder.
