I have a 2010 Rsv4 factory and on occasion I'll get the dreaded SERVICE displayed on dashboard and bike goes into limp mode but I am always able to get it to behave again with one or two key cycles. I recently got myself situated with Guzzidiag and pulled code
(P0124- stored invalid signal)

seems pretty vague to me as there's quite a few things that the PCM could get an invalid signal from!!

i did find this on a post tho P0124 = rear throttle position potentiometer.

I'd imagine the potentiometer is inside the electronic throttle body! Have these been problematic in the past?

thank you guys!

Yes the throttle bodies have been known to fail.

rear throttle position potentiometer P0124
• incongruent signal

Error cause
• Potentiometer 1 and potentiometer 2 do not show a logical value: the sum of the two voltages should be constant. The cause may be a malfunction in one of the two sensors or an abnormal resistance in one of the two circuits

Troubleshooting
• Check the throttle body connector as well as the control unit connector. Check that cable resistance between the throttle body connector (PIN 1) and the control unit (PIN 48) is a few tenths of an Ohm. Check that cable resistance between the throttle body connector (PIN 4) and the control unit (PIN 50) is a few tenths of an Ohm. If one of the two is different, restore the cable harness. If correct, replace the complete throttle body.

NICE Plocky!! You the man!

NICE Plocky!! You the man!
Thanks, but I owe that to the service manual.:o:cheers:
Anyone can look it up.
I just happen to have the 2009 & 2016 RSV4 service station/workshop manuals.
The 2009 I found a free link to somewhere a couple of years back.
The 2016 I purchased for my own bike.
They're only $8 at AF1 anyway.

if you took the time to look that up in the manual for me I'm even more grateful. And I'm apparently blind as I bought AF1's service manual on a thumb drive and had staples print all 400 something pages and I put em in a 3" ring binder and sleeve protected each sheet and I couldn't find what I was looking for in it. But now that I know it's there I'll look again. You remember what page/pages you found that info roughly?

That's the beauty of the PDF, just search the code & you're there.:)
