V9 P0336 crank sensor error - SOLVED

[tris]

Morning All
I was 40 miles into a 240 mile trip and stopped for a quick bite to eat
On restarting the bike I got an engine management light permanently lit.
Switching off and restarting did nothing,  nor did "ride it for a few miles and see if it goes away"
So I abandoned the ride and rode home to fin out what was occurring.

Guzzi Diag says its a P0336 error - speed sensor

After being stopped for an hour at home, I started the bike and the light went out.

So I guess that I have a temperature sensitive issue with the crank sensor, so will find a replacement.

Is there a list of equivalent parts for the V9/V7 anywhere?
It looks like a bog standard Bosch part (0 261 210) but I'd like to be sure

Also, could a dodgy/dying crank sensor be the cause of my ongoing  snatchy throttle at low rev transition?

Cheers

OR gap sensitive, could have grown a touch. Worth checking.

Check the Ohm's & harness connections too.

Grrrr

Replaced the crank sensor yesterday and gone out for breakfast.
Stopped bike and got another error. 

I'm guessing I'll be doing a deep dive into the electronics and  connections when / IF I get home

Oh well

[tris]

Yep, same error 




Bike started good as gold when cold and ran fine, until I stopped and restarted it when warning light illuminated.
Bike rode home with no issues

I'm trying to get my head around what to next

Can this error be caused by an earthing issue

Any suggestions to find the route cause would be appreciated

Cheers

PS I think it overheard me talking about moving to a V85, so it's sulking

SOLVED

I broke, cleaned and remade (Inc vaseline) the battery and earth connections

Since then I've ridden it about 110 miles with 6 or 7 restarts and no warning light

A "good" ie cheap Guzzi solution 😁
