Are you talking to me or Rex, stoutner?

I was talking to you.

They replaced the TPS sensor and the sled runs great now.

is the tps the same as tors?
sorry i am not familiar with the tps.
can anyone explain how to test the tps?
Thanks for all the input guys.

i plan to argue the oil changes when i pick it up but for now i am shutting my mouth because we are quickly running out of winter and i want the sled fixed right and returned so i can ride!!

TPS (Throttle Position Sensor) located on the throttle bodies.
TORS (Throttle Over Ride System) Safety switch in thumb throttle.

the tps is throttle position sensor....different than the tors ...throttle overide ...
I'd tell them you had bought all the stuff for the oil change already and was going to do it yourself...at worst they'll negotiate with you...and if it was a little more reasonable...I'd let them make the doe...with these sleds it helps to have a good dealer on your side...

To test:

1. Locate the switch - It is at the left end (Clutch side) of the throttle bodies. It has 3 wires coming out of it. One is 12 Volts DC into the switch, One is ground, and the Yellow is the TPS output wire.

2. Cut into the Yellow wire (or follow it to the connector) and hook one lead of your DC Volt meter to it. (The connector must be connected though) and the other lead to ground (Engine or frame is good enough).

3. With the ignition key in the "on" postion, check dc volts. At Idle position it should be about .5 - .9 Volts DC. At wide open throttle it should be about 4.0 - 5.0 Volts DC. Half throttle or so should be about 3 Volts DC etc.

NOTE: The sled does not have to be running. The key must be in the on position with the kill switch not pushed in. In otherwords, your gauge pod should be on.

The TPS switch is held on by two screws and the switch itself is slotted. You can adjust it a little but you should try to get it at about .6 Vdc at idle. Just loosen the two screws and turn it slightly and you will see you voltage change.

My experience with TPS's in the auto industry is that they can have an intermittent reading at various points across the sweep of the sensor. The most common place for wear is at the beginning where the contacts spend most of their time (idle and part throttle, unless you ride like I do...)
The right way to test one, but not the easiest, is to record a slow sweep (from idle to WOT) of the sensor with a meter that will display it as a graph. Any little blips will fool the ECM and cause it to run erratic.

O.K. Lets not get carried away. A Graph???? A good digital meter will work just fine. Just leave the leads hooked up and slowly work the throttle back and forth.

P.S. The girls at the Glenmore were asking where you wer this past weekend.

 

[mbarryracing]

Ah, AMY !!!!

Wayne, your right. The Fluke digital meters I have used had this graph option, but even with just a number readout it serves the same purpose as you swipe the throttle from closed to WOT slowly. Watch for the numbers to start jumping around.
I hate electrons... Give me a wrench or socket anyday.

If you happen to have a PCIII you don't need a meter. There is a calibration for the throttle in the software and it gives you values for throttle closed (idle) and all the way up to wide open throttle. Just hookup the PCIII to a computer with the ignition on (doesn't need to be running) and go to into "set throttle position". There you can set the closed position and the wide open position. I know not too many have a PCIII just FYI if you do.

They replaced the TPS sensor and the sled runs great now.

So did you pay for the oil change and chaincase service?

I think you have the 2 of us confused.
number1kyster had a similar problem and had the tps changed

i have not been to my dealer yet to pick up the sled. it is 2.5 hours away from me in maine. I will let you know after the weekend.

Guys,
Thanks for the info on the tps.

 

[**sj**]

what about tps settings...anyone find any power by adjusting??

Ok so I finally have my issue resolved.
I tested the TPS every day for a week straight and
was finally able to get it to duplicate the idle issues i was having.
I brought the tps to the dealer to have them test it.
they looked up the part number to see if they had one in stock. turns out they had 7 in stock. The owner of the business immediatly realised that the apex tps part number was the same as the part number for the TPS in one of the yamaha street bikes they recently had a safety recall on. from what he told me the bikes would run great but when they came to stop at intersections /etc they would stall so yamaha issued a safety recall on the TPS.
Just wanted to give the people that responded to me an update. sorry it took so long.
