In a post I read something about checking and caliburating the ohms on the throttle position sensor and resetting the ECM. Does anyone know anything about this, they said it was in the service manual. I can't remember where I read the post.

 

I have reset the ECM and it does absolutely nothing. They say you reset it after you do mods, I think. If you want to know how to do it, I can tell you how.

 

I have done a few mods and would like to know how. the post about it was stressing the part about the throttle position sensor have you heard of that?? they said that the adjustment really woke it up.

 

Yes, there is a throttle position sensor. (TPS) It just basically tells your tranny when to engage and stuff. Not much more than that. Here are the instructions. It couldn't hurt to try it out, just to see if it does anything.

Step 1.
With the vehicle stopped, put the gearshift lever in "N" (neutral), be sure that the neutral indicator comes on and turn the ignition switch to "off".

Step 2.
Turn the ignition switch to "on" while pushing the UP and Down shift switches (gearshift switches) simultaneously. The "N" on the gear position indicator starts blinking.

Step 3.
Within 5 seconds after turning the ignition switch to "ON", push and release the gearshift switches in the order of UP switch, Down switch, and UP switch. (Do not hold onto the switch)

The gear position indicator displays "- -" to indicate the system enters the intial setting mode.

If more than 5 seconds elapse or the procedures are incorrect, The "N" stops blinking and stays on. Repeat the procedures from step 1 at this time.

Step 4.
Move the throttle lever to fully closed position, then to fully open position, and then move it to the fully closed position again within 5 seconds after "- -" displays on the gear position indicator.

Step 5.
When the initial setting procedure is complete, the indication on the gear position indicator changes from "- -" to "N".

If the "- -" on the gear position indicator blinks, repeat the procedure from step 1.

 

Yellow650 I found the post (true rincon cant wheelie 3rd page.) are you familiar with this? do you have the manual? If so does it say how to adjust the setting.


Second, but VERY important, have your dealer ohm out the throttle position sensor using the procedure in the Service manual, Section 24 page 44. Check the book. If it says ohms between terminals A and B is 490 to 510 ohmes, the book is a misprint. NOTE MISPRINT. The proper setting is between 580 to 620 ohmes.
My machine was set up at 490 ohmes and ran like sh-- for 6 mos. until I found out about the correct setting and notified my dealer.For the last 2 rides,in the snow, I can now get out of first gear and into second. Can you say 20Km. before to 40 Km/hr now??????????????? That is what I'm talking about. Pass the word. Tnkx. Bushcrasher.

 

How would the TPS ohm resistance make it run different? I mean as far as I know, the TPS and such really only controls transmission engagement and the proper gear selection for the throttle posistion. Mine runs fine, but I might look into having it checked out. Thanks. I will pass the word.

 

so what's the deal with the TPS's on Ricon's I work at a Honda dealer and not had any one come in complaining about there Ricon's

 

I dont know that is why I am asking I would love to see a manual and do some reading. I think I might buy one. Or mabye find someone who works at a dealer to look it up (hint). I don't know if the guy on the other post knows what he is talking about or not but i would like to find out. By the way the other post is on this forum under true rincon wont wheelie (page 3).

 

I saw that post to and not sure what that all means. I'll be keeping my eyes peeled to see if somebody can answer your question. I have a Rincon and want to learn as much as I can about them.

 

It seems two different but related service procedures are being discussed here. First is the resistance of the TPS, mounted on the side of the carb. It is possible to loosen it (it's mount is slotted), to get the proper base resistance. You're gonna need a digital multimeter to inspect it. It's not a common or maintainance related item to mess with it. If you replace the carb, have the TPS off for some reason, or your machine has issues, it's not a bad thing to inspect. The second thing is the initialization procedure, so accurately described by Yellow650Rincon. This synchronizes tran, electronics and carb. You need to do it if you replace any related electronics for sure, if you change the TPS resistance via the first procedure, or if you make a major change in idle speed, or throttle cable free play. This is easy and don't hesitate to try it if you need to, you can't really mess it up.
