I have a '99 SX 600. The TORS was kicking in so I unplugged it and jumpered the leads to see if the sensor was the problem. It now runs like it always did but, does this tell me the sensor is bad? If not, what do I need to check on the sensor? I am assuming an ohlm reading at various throttle positions will tell me the condition of the sensor but, I have never had to check one and don't know what the readings should be. Anyone have some advice?
If it is bad, does anyone have one they would like to part with?!

There is a ohms reading for sensor info is in service manual if you cant find it on TY site I can get it for you tonight when I get to shop. I am also looking for a sensor if anyone has one.
Did you try adjusting the throttle cable first?

It's not a sensor, it's two switches. Which means it's either open or closed. One switch on the carb rack, the other is in the throttle block.
While this maybe true the switch or sensor on the carb rack has a variable resistance when you go from idle to full throttle. Do you still need the procedure for testing the sensor?crewchief47 said:
It is a on or off switch, no in between!
Jumping the switch @ the carb rack cleared
Up the problem so i know ît is that switch. Do they get dirty and stick and Work if cleaned or is ît not worth trying to clean?

You never answered the post of is your throttle cable set right? This is very important. 99% of torrs problems is a improperly adjusted throttle cable. A test with a ohm meter for resistance will tell you if the switch is bad. It is a simple open or close like chief said. The post above by daman is very nice.
The TORS switch on the carb rack can indeed be taken apart and cleaned as it is just a button type switch.I had mine apart last fall when I had the carbs off to be cleaned as mine was also not working right,they get dirty inside and the contacts wont work.It's not a great big job to do it just take your time and make note of the steps involved in taking the switch off the rack and taking it apart.Get a can of electrical contact cleaner to spray the dust and buildup in the switch out and mabey give the contacts a light buffing with some fine sandpaper.
Yes, throttle cable is properly adjusted. I Will clean the switch & reconnect to see if the problem is corrected or not

I'm a little confused on what your talking about. The TORS switch on the rack is an off/on switch, not a variable resistor style like a TPS on a car. Yamaha has used TPS on a handful of their 2 stroke sleds but I'm not sure which models they were. At any rate, the TPS sleds also had the TORS switch. If you are getting variable resistance and you are sure it's the TORS that your checking than the switch is likely FUBAR.

I Am Talking About The Tps Switch Both My 97 And 98 600 Twins Have The Tps Sensor On The End Of The Throttle Shaft.
