Polaris Virage I TPS sensor option.

[kingdill]

I have done alot of digging and cross reference work to find the exact sensor now 2 companies later but just built mine. The sensor once made by invensys is now the 90?? honeywell HRS100SWAB090. Very little modification just adding the flat face keyway to the stock round shaft. Would post a picture of mine completed with the stock housing and plug but I cannot. Thank you hope it saves you big as I could not even find one. Cost me $41cad shipped.

Did your original TPS look like this?



or this?

Can build and fix anything but it took me a day to figure out how to ad an image lol

[kingdill]

Where did you find that honeywell entire sensor? And how much? I was seeing unavailable and a few for mucho dolairo

[kingdill]

It's just a hall effect 90?? potentiometer

Did you confirm the correct TPS output signal voltages at idle position and wide open throttle position?

[kingdill]

Oh yes honeywell provides all technical specs on thier website then I confirmed before installing. Works perfect. I was getting a failure to return to idle almost a runaway scenario.

A good way to make sure you make the flat face exact is if you put the new and old shaft to shaft the flat spot is opposite like a mirror but if you keep the new sensor at fully closed and the old full 90?? open it positions the area perfectly for making the mark to get the flat face exact. I made a super easy jig to make sure both were true and level with the lock stakes. Shorten the shaft til the slot is and it's perfect. Hope it helps the availability and prices are completely insane. I ordered mine from my go to for all my electronic and circuit needs. Arrow and I think digikey had them too.

Idle voltage check is done with the TPS installed and powered by 5 volts (EMM service power jumper in place)..

TPS output at idle should be about 0.370 volts, ranging to maybe 0.470 volts, with throttle lever released and a tiny bit of slack in the throttle lever cable.

Wide open throttle lever squeeze should provide about 4.5 to 4.7 volts TPS signal, IIRC.

[kingdill]

Yes the sensor provides 4.7-5v max. The potential is 0.3-5v over 90?? in 1?? increments.

To be clear this is the current version of the exact sensor chosen by the manufacturer. Invensys is gone was taken over by Schneider electric who was purchased by honeywell. It just does not have the basic requested shaft specifics as ordered by the manufacturer. The model number I provided needs to be used. There are many variations clockwise counter cw, 3 pin,180?? with my background I was able to know what It was and what i needed. Just sharing my end result to save everyone from paying for a housing and markup from the massive inflation.

Excellent work! Lakeside Tech was going to make the TPS investigation a priority come winter, now I don't have to

I wonder what the minimum order quantity is for the version with the flat. And I wonder if someone still has the ability to make the molded housings.

Could you share a photo of your machining jig, and a photo or two of how you marked the shaft for the flat?
