P0335 Camshaft sensor: no signal

[Kaladin]

My 2007 Norge has the red triangle warning come on intermittently, but getting more mittent.  Guzzi Diag says P0335 Camshaft sensor: no signal.

The bike still runs like a well-oiled top.   
Any ideas?

thanks

  Likely swarf on the end of the sensor. Pull it out and clean it off  see what happens. My $.02

You got your warning, I'd get one. That's just me though, if you pull it have a new one in case there's no issue.

intermittent failures of inductive sensors are most often wiring faults. Pull the harness connector, clean it with Caig DeOxit, and see what happens.
You won't have swarf because it's inside the engine unless you have more serious issues internally.
The sensor is captured so it can't back out or have bad bearing clearance like automotive ABS sensors.

*if* the sensor is going bad internally, which they do, the failure will show up when the sensor is hot, such as idling in traffic on a hot day then return to service as it cools. This starts slowly and becomes more frequent and at lower temperatures until complete failure.

 Actually, the sensor see's all kinds of hot oil which carries microscopic metallic particulates the oil filter doesn't remove and over time it builds up on the end or the sensor.

Thanks.  The triangle usually comes on when it's cold.
Do I have to pull the tank to get to it?

When mine when out, it went intermittently- worked when cold, not when it warmed up.  And when I checked the resistance (cold), it was within spec.  Never checked it warm.
So, I agree with Steve to have one on hand.
