    Virage TXi Throttle Position Sensor

    Hey guys,

    I've got a question about the forever failing TPS sensors. I GENTLY wiggled the harness on mine while the engine was running and when I do so, the engine RPM goes up a few hundred RPM.

    This doesn't seem normal to me. Does this sound like a symptom of a bad TPS? The part number on it is 06540.

    Tps is good .The connector contact is bad .You need to crimp the connectors with some pointy nosed pliers to make sure the contact is good .I am sure this was recomended by K447 in one of his posts .This caused me more problems than anything until I found it causing the problem I was having

    Cheers

    Bernie

    Have a look here.

    Have a look at each connection pin and socket, and clean them up if they are contaminated.

    On my own Ficht machines, I used thin pliers to gently squeeze each socket a little tighter.

    I also replaced the TPS on each machine with a new one, and put the old TPS aside as a spare. The newer TPS is a better design, with a sealed 'overmolded' body...

    Bernie/K447....my brothers from another mother.....thank you.

    My Virage is a 2001. My TPS looks nothing like either of the two that are shown in that link, K. Mine doesn't have the pigtail attached to it. It's just the sensor with a connector built right into it with no exposed wires.

    I'll go ahead and use pliers to make the connections tighter.

    I'm about to place an order for several things, so I'm going to take your advice and go ahead and order a spare TPS.

    Just out of curiosity, do you guys know if the TPS I have is prone to the same failures as the "old ones" from the newer model Virage machines?

    The original non-pigtail TPS are also prone to vibration and moisture induced failure.

    They don't all go bad, but many do.

    I don't think the newer pigtail TPS will reto-fit to the older throttle bodies that originally came with non-pigtail TPS, but I am not 100% sure.

    Yeah....that's the little bugger.

    I'll just put whatever new one on Babbitt's sends me and do as you suggest - keep this one as a spare.

    Thanks guys!!
