A stumbling motor or erratic tach? I don't have an ST3 though.

Maybe pull it and check for swarf?

Have a good one.

 

Well, I guess I'll first check all the wiring connections and reset the error message. Then I'll go for a nice ride over the weekend and see if the message returns. Like I said, it seems to run just fine so maybe it was a blip.

 

Well when mine failed it was not a total failure. The bike would start up and run until the engine got to normal operating temp and then quit. The engine would always restart but would die at about 1700 rpm. Hardly enough to get back on the road.

So I would sit on the side of the road until the engine cooled enough to ride again. Might make two more miles or ten. I'm sure every failure is different but that's my experience. Got another off ebay and good to go.

 

I got the same code this season. I have had intermittent stumbling at 8,000 rpm...I think that triggered the code. I purchased a new sensor and a set of shims. If the sensor dies, I'm ready.

 

How much does the sensor go for and where'd you get it?

 

I went with a new OEM unit from Ducati of Omaha...I think is was about $120.

 

Error message returned after my ride today.

Guess I'm buying a replacement.

Is there a listing of error codes on the site?

Were there any symptoms...like the bike misfiring or something? Some folks posted in the past that the sensor face could be gunked up. May want to check that first...and check the sensor gap as well.

When you think about it, how many CPS's have gone on your car? Even though I bought a new sensor...I won't install it until I confirm that the one on the bike is dead. Of course that may leave me stranded...

Ha! I just ordered a used unit from site supporter Gotham Cycles. Oh, well. I'll try cleaning the old one and have the spare just in case. I should probably order the shim kit for it, too. I saw them on someone's website - can't remember who.

Thanks for the error code list, but I should have mentioned that I have the 5am that uses different codes. Mine says P0335.

Now, as far as symptoms... I was paying close attention on my ride today (a nice 6 hrs.) and noticed just the slightest bit of stumbling around 4200 rpm. Thing is, it wasn't consistent. Who knows, maybe it is just all gunked up.

 

What the f-ing hell?

Has anyone ever taken out the crank sensor on a ST3? It's like one of those idiot tests. It comes out to the point where you need two more millimeters for clearance. Do I really have to remove the lower water pump hose? Really?

 

That area should be similar to the other STs except maybe the 1998 ST2. If you wiggle it just right it will come out.

Have a good one.

 

OK. Got the sensor out. That was definitely an exercise in patience. Not looking forward to putting in the replacement when it gets here tomorrow.

Anyway, there was some gunk on it, but in my opinion, not enough to cause it to malfunction. It does look like it has some scoring on
the tiny pickup (but nowhere else), so maybe the air gap was too tight. I didn't check that before removal. Why would a properly adjusted gap change? It's not like these things wear or need adjustment regularly.

I'm kind of tempted to put it back in, check the gap, and try it out, but I guess I'll put in the other one.

 

Flywheel nut tight? if it loosens it can wiggle on the spline and rub the sensor.

 

That would really suck. But I don't think that's the case. The plastic that surrounds the metal pickup doesn't seem to be worn at all. I'll get a real good look at it tomorrow.

BTW, the sensor is made by Bosch so it's probably found in plenty of other vehicles.

 

It depends. A bit of swarf could mess with the signal depending on the field it generates and if it shifts the timing.

From my experience, an inductance sensor can never be too close as long as it doesn't contact. The closer, the more accurate the signal.

Have a good one.

 

I stand corected. it does not read off the flywheel but a driven timming gear very close to the flywheel. It's been a few months since i had my fairings off and at that time i pulled my pick up to check for swarf as i had the fairings off.
Soyour rub must have happened by some other means.

 

I got a really good look at it under a magnifying glass and there are scratches going across in an arc. They're in the plastic too. There's also a gouge going across the arcs.

Keep in mind that you need a magnifying glass to see them so these things are incredibly minor. Delivery of the replacement was pushed back a day so I'll compare it to the new one tomorrow.

 

Replacement is in the same physical condition as the original, for the most part. The scrapes must be from the manufacturing process. Here goes...

 

Good luck.

Have a good one.

 

It was a lot easier going in than it was going out. Now my problem is that my feeler gauges are too wide to fit in the plug hole. Arg!

 

Always something!

 

got a "Sharpie marker" handy? coat the end install the pick up turn motor over (don't start it) remove pick up if the sharpies rubed off your to close if not pull a shim and retry. add one shim after rub is found. Or with no shims pus in the pick up and see if your feelers will fit under the mounting bolt area say you fit a 0.1mm under the hold down tab so you need to add a 0.5mm shim and a 0.2mm shim to get to clearance spec of 0.6 - 0.8 make sure you at the proper spot on the gear if trying it this way.

 

Good tip. Or I can buy a tapered gauge set off Amazon since I have company all weekend and can't ride anyway.

 

The best part of "projects" is the opportunity to buy more tools!

 

I found this set while on the high side $$ wise. Seems to work well on my ST4 However I've not tried it in the pick up window.
Added plus is it's made locally to me, so in a way I keep friends working.

your welcome to ride up and use'm

 

Thanks for the offer. It's good to have a support network! But, family obligations this weekend. No riding for me. Should get a nice steak dinner out of it though.

 

crank position sensor

I had a problem with my 2002 st4s about 5 years ago. The motor died and would not start. I was at my local independent shop when it happened and Bruce Meyers was there for a Ducati maintenance class. After verifying we had fuel we checked the plugs. NO SPARK. After checking connections and battery ground to frame he went to the CPS.After pulling it out, he just took a measurement from the outer edge of the cover and then measured the sensor with the shims that it had. He removed one shim and the motor started right up. I haven't had any issues since. tm

 

Just pulled mine out as I was getting the same error code. I found a piece of what looked like grey PTFE tape in the hole. I removed this and cleaned it. I need to check if it has made a difference.

Also found this on EBAY and was tempted to try it. Anyone see any words on the sensor?

The barrel of the sensor looks too short and the connector is all wrong.

My old sensor has two sets of numbers stamped into it. 490 51 124 and 0 261210. It's made by Bosch.

 

Excellent! I'm still good for tomorrow,if you want to do a test ride,I'll be the chase vehicle,..just in case.
