Throttle Position Sensor

[Paul Weaver]

Hi Chaps,

Recently had a service and the mechanic said that he got the closed throttle ohms to 1100 but couldn't get the higher one / open past about 2500. I'm picking it up tomorrow and I'll see what it feels like but does anyone know what potential difference that would make in terms of 'feel'. I haven't noticed anything wrong with the pick up at all.

New TPS need to be ordered or could it be an issue elsewhere?

Cheers
Paul

The bottom throttle value can make your bike behave very badly if out, the upper value is not so much of a problem. If it is riding OK I wouldn't be in a hurry to change it out.

This!

Well, got the new meter & guess what?  It's got a different reading on the resistance than my old meter. Checked the original TPS & it's fine! Just could have done with some adjustment, but the readings I got said it was shot, hence I brought a new TPS.
Min reading was .511 & max was 4.94, so the scope for 1.1 - 4.6 is certainly avail on my 'old' TPS. Now I've got 2 of them! 

Will have to set the one on the bike now as it was just 'wound' round as far as it would go, so room for improvement there then. Bit too cold & wet to be bothered going out to the shed tonight, it'll wait till a warmer afternoon / evening.

So, all's well that ends well. I've now got 2 meters & 2 TPS's.  Thanks for the tip on the new meter Grog, it's a 'meaty' lump isn't it. Hell of a lot more functions than I'm ever gonna use though. Got it for just under $50 on this side of the ditch.

Cheers

Might want to read the rest of that thread as well.

Hi Paul, reckon you'll find it rides fine.  1.1Kohms is great, the upper range doesn't seem to be as important, it'll still wind right out on the throttle. See what you think once you pick it up.

I agree with Col. If it revs no prob.
