2005 Rancher AT 400

I was told my angle sensor might be bad and that is what is causing my ESP to blink "---" and will not let me go in reverse. Does anyone know what this sensor looks like, where to find it on the quad, and/or how to take it out and check to see if its broke. Any help would be great. Thanks.

I am not familiar with that quad, but that is what my Rubicon does. Do you have the little knob that lets you change from D1 to D2 to ESP? If so you probably have the same tranny as a rubicon.

Although the angle sensor is a common fault with these quads, I have had electrical problems cause the same thing. When the relay for my winch was shot, I would get this error and if I screwed around with the winch control I could get it to go away.

At any rate, the angle sensor is accessible if you take the left side panel off the engine. It is right on top. I am pretty sure I found information on this site regarding checking it and I think some people have even removed them and resealed them to get them to work. Try a search, good luck.

I do not have the D1 to D2 to ESP switch but i do have the AUTO to ESP switch along with the hondamatic tranny.

I have a 2001 rancher esp and am having tranny problems too. Sometimes it will shift into reverse with the electric and sometimes it wont. Any help would be great. thanks

The angle sensor would do it. Those sensors seem to be common problem from what I've read. This link SHIFTLESS WONDER! - HONDAMATICTM AUTOMATIC TRANSMISSION - HONDA'S CONTINUOUSLY VARIABLE TRANSMISSION - Dirtbike at Off-Road.com very well illistrates the importance of the Hondamatic motor-swash-plate and its angle in the operation of the Hondamatic auto trans.

In simple terms, and parden my french, if that angle sensor is sending wrong info, $&!# gets F@*%ed up with the trans.

I'd go to a Honda dealer for more advice. I have an '05 Rancher FourTrax 400 AT and nothing has gone wrong with it yet, but i plan on going to pick up a new angle sensor anyway.

The angle sensor is on the clutch cover beside the shift control motor ..
The angle sensor tests are more accurate if you test the sweep with an old analog type ohm meter ..

**Above is an '04 Rancher 350 i believe everything is in same location**




hope that helps
