Few questions about a cali 1100i?

[guzzisteve]

They mounted the EVAP can(black) one on each side next to rear fender off of frame.
If you follow hoses from intake, they should end up there.
Should be in parts book if you have emissions in Ireland.

Thanks Patrick! You're more than welcome, I'll look at them now after a voltage test. Tuner cleaner being carb cleaner? ?

NO.  Carb cleaner has petro distillates that will contaminate and have particles cling to your contacts.  Electronic parts spray cleaner.  Leaves no residue.

If you have to buy another TPS.  You can buy one from at a HD dealer.  Just give them the part number.  Don't tell them that it's going onto a Moto Guzzi.  You can probably buy on Ebay.

See this old thread if you want to replace the TPS.  The Harley part is (was) a lot cheaper.  I think one of my EV's has the Harley TPS or it is in my tool bag as a road spare.  I couldn't tell the difference.

The TPS setup is 150mV with linkage fully disconnected and butterfly backed off all the way.  Once reconnected and adjusted, the TPS will read something like 385mV.  It is VERY sensitive.  Just tightening the screws can move it 50mV plus/minus.  Be prepared to fiddle with it.  Pretty much set and forget once you get it right.  Nothing to make it change unless the electrodes get dirty inside or someone tampers with the screws.  BTW, the reason the sweeper electrodes get dirty is because the TPS resides BELOW the throttle body.  When you stop the motor, there may be some fuel mist in the intake tract.  That fuel condenses and drips down the butterfly shaft and into the TPS.  Once it evaporates, all the fuel additives leave a residue film behind.  Hence the reason that electronics tuner cleaner can restore the rheostat function.

Look again at your spark secondary wires.  Especially look at the right side wire, about halfway down where it passes the base of the cylinder.  I have seen a number of them seriously chaffed here and sending stray sparks all over.  Wrap with protective sheath as necessary.

On my EV the TPS had a weared out part off carbon track on the plastic foil inside. Just at cruising speed. Got a TPS from a Ducati.(identical)

I'll have a look, thanks. Electronic parts cleaner so just isopropyl alcohol?

[lad]

Is this the TPS? Looks like a pain to get to, remove linkage arms etc?

[Tom H]

TPS S/B under the LH TB. Look at the posted pic and you'll see the same under the TB.

Found it sorry, didn't realise there was only 1, I thought each manifold had one. Looks pretty cruddy to be honest, rubber on the manifold there doesn't look to good either. I've get the meter on it and then pull it...

thanks

[Tom]

I did a quick check on Ebay out here.  They're different vendors selling TPS's.  YMMV in Ireland with Ebay UK???

What color is your bike?  OEM?

tps would be similar to this.        https://www.amazon.com/Throttle-Position-Sensor-Potentiometer-California/dp/B07ZQM66J1

HD makes two very similar versions (Marelli actually).  Look at Tom's picture.  You need the one that has the semi-circular slots Tom shows to allow for rotational adjustment.  The similar version just has round holes to take the fixing screws and is thus NOT adjustable.  That one would be for a different bike where adjustment is done via software.

The original TPS is a PF3C. The Harley one is a PF4C. "Almost identical"

This one pictured is the PF3C.

[LowRyter]

good luck finding a Harley TPS

This one is supposed to be the plug and play to the Italian bikes, PF3, not PF4.  I think all of them are Chinese knock offs now but that's all we can find.

reading ahead, it was determined to be incorrect.  The striked info applied to 1998 and later models.

[Tom]

Y'ep exact same one I posted earlier.

[Kiwi Dave]

I think you have the same TPS as my 98EV.  You can drill a hole as shown here by the little white spot.   Spray in 'tuner cleaner', work the pivot, blow it out with air.  Rinse and repeat.

The specified TPS for the California 1100i is a PF09

[ejs]

The older TPS... PF09

[lad]

The specified TPS for the California 1100i is a PF09

Seems right, have a look at this, but bear in mind my frame number is 152XX;





That said, it looks like someone has put on a PCF3, not sure would it affect it?

[lad]

The potentiometer in question...nothing ever looks good under a phone flash

To my eyes, it looks like the PF09 would line up better with the injector housing and would have that little gap....?

Yeah that's the fellow, here's one in Germany at a good price if anyone is watching this from the EU

There is a # on the sensor & wire goes in from it's side.

[John A]

I think of it like this: fourth gear is overdrive and fifth is double overdrive. Spend most of your time in third or if there is no load , fourth. They are geared tall, always have been. Third is great for hills and passing.

What are you talking about? The TPS? It's long since located and identified

[guzzisteve]

Never mind then.

[lad]

Never mind then.

I didn't mean to sound dismissive, just trying to keep all these information-plates spinning, it's all new to me.

I can't back-probe the TPS, just isn't working for me, not sure what i'm doing wrong. I'm going to try read it off the P8. How awkward is it to remove the passenger seat? The ECU pulls down enough probably, but just wondering.

Also the info Tom H sent me from http://bradthebikeboy.blogspot.com/2012/10/throttle-position-sensor-setting_21.html seems waaaay more complicated than the pdf from GuzziSteve, which boils the procedure down to a few steps...





What am I missing? Why is one so involved?

The rabbit-hole is mighty and wide

[Tom H]

For the moment ignore the voltage reading numbers. You will only care about if the voltage increases smoothly as you turn the twist grip throttle. Latter, if the TPS produces a smooth voltage increase or need to replace the TPS, then the numbers per the instructions/manual will be needed.

You need a multi-meter, digital works for me. A paperclip broken into 2 pieces or a pair of sewing needles or straight pins. Use a pair of alligator clips to hold the multi-meter contacts to the pins.

FYI: Guzzidiag software/ECU reading is mot sensitive enough to read TPS voltage. But it will read the TPS/butterfly degrees.

As in the links I gave you........

With the connector to the TPS connected. Slide the "pins as above" along the wires and into the TPS connector where they enter the plastic connector. You will be looking for contact with the wires in the plastic connector when the pins are slid in deep enough. It may take a few tries.

The only reason for doing it this way is to not put a pinhole in the wire outside the connector that could allow moisture/corrosion in to the wire.

Your TPS in the picture looks kinda grungy. It "could be just fine", but if it were me I would check it before replacing. Always trying to save a buck/pound./Euro.

Hope this helps,
Tom

I'll give it another go, tempted to just cut into the wire and shrink wrap it after

[lad]

I can't get it to work...? 

Is there a trick? I can see the pins are coming down and out through the connectors:





Just not getting a reading, even though I'm getting a reading from other parts of the bike...

Ignition on, bike not running...
