Anyone have one lying around. I need to verify if my TPS is unhealthy Can you even buy that part. I've just read that it's part of the TB's at £1500 a set!! How can I test it?
If you have a power commander 3 or 5 fitted you can see a open or closed throttle and it shows that as a sensor voltage. generally under 1 v is closed and 3 - 4 v is open. If you test using that then you will see that part is working OK. You will of course need the PC3 or PCV software installed. Also for the same token you can test the voltage on the sensor using a multimeter however as to which is the live I dont know. Simple way is to stick one end on a wire and the other end of the voltmeter to a ground and check all three wires until you get a reading of around 0.5 volt with s closed throttle. Once you have that open the throttle and see if you see a roughly 3.5 volt readout. You dont need to have the bike running to test that.
You should get DTCs if the voltage is out of range but for ref gray/black is -tive yellow/red is +tive
