Pressure sensor

[Rcevans]

2006 Apex. Is the throttle pressure sensor mounted above the carbs part of the TORS and is it the only sensor for the TORS?

Your question is somewhat confusing. The TORS is a simple switch that is located in the throttle housing. When the throttle is pressed, it moves forward and in slightly to close the switch and complete the circuit. This way the ECU knows the throttle has been pressed and allows the engine to rev. The TORS does also monitor the speed sensor. There is a barometric "pressure" sensor that allows the ECU to read atmospheric pressure. But I don't think that is what your asking about. And there are no carbs on an Apex. Fuel injection, my friend.

Throttle 'position' sensor does double duty. It feeds info to the ecu for fuel and timing mapping and also works with the throttle safety switch at the handlebars for the TORS function. There is no switch at the throttle bodies anymore like older sleds had, that also had a TPS

The switch at the thumb appears fine. Just wondered if the TORS worked in combination with a sensor. Sounds like your saying the TPS does. There is also a pressure sensor above the injectors mounted that is plugged in. Was wondering if that did too. It is made by NB Denso. Sled idles great but still wants to die as soon as RPMs get to 4k. Can be idleing and I can pickup rear end and drop it and it dies. Can be idleing and I can stand on it an pull up on the handlebars for left and right ski lift and it dies. If I turn on key and and no fuel pump charge I can pick up rear end an drop it and pump charges up. I have new red relay and it all comes back to excellent idle but as soon as I start a slow accel and right before and sometimes right at clutch engagement it dies. Have checked all wires for fit an corrosion and none. It all comes back to think the TORS has a sensor or something that works in conjunction with handlebar switch?

And I can say a couple times during troubleshooting it did throw the ER-1 code. Not always but a couple.

Sounds like you have a connection issue somewhere.

I thought so too, but I have jiggled and checked every wire while it's idleing and I cannot get it to break a connection and stall. It's only at the 3 to 4000 RPM acceleration that it stalls

Keep looking. Check the 'finger' connector blocks located in many places through the harness. In particular, locate the ones that share the same wire colours as the TPS. Pull the finger out and clean it.

Did you look at all the grounding blocks? I had similar issues a few year back more so the one in the nose of the sled.
