New member here,
I have searched here and other places and have not found an answer to my problem. As the title says I have a 2014 420 Rancher that recently started having an issue were the revs before the clutch engages.
I have checked the oil level (per the service manual) and replace the Valvoline ATV 10w40(less than 5 hours) with 10W30 GN4 for good measure. I have used the "pin" method to pull a DTC. I shows a 8-1 which is a TPS error. This makes some sense, as if the computer doesn't read throttle position correctly, it could have this symptom. I have checked the source voltage, and tested the TPS off the quad with a Fluke and a power supply at 5v. It is smooth and does not seem to be a bad sensor. I am confused by the DTC, because the PS light blinks the code, not the check engine light. However, there are no PS codes of that value. This condition appeared after a couple days of driving in the cold (~32°) and driving though some water/bogs.
A couple questions. First has anyone seen this issue, and do you have any suggestions? I have followed the troubleshoot right up to the point of replacing the ECU, which I don't seem to have one on the shelf :)
Second, anyone used a OBDII reader with an a 4pin adapter to pull codes? If so, what system do you use?
Beyond the rev issue, the quad runs and starts perfectly and when it decides, the clutch grabs tight (no slipping)
Just picked up a 2003 Yamaha Kodiak 450 ATV. Doesn't run and it's been sitting out in a field for a while faded bodywork, seat's a mess, dead but it rolled so I figured for $100 what the hell, SOLD! I have no idea what could be wrong with it, first thing I guess is hook up a battery and see what happens. I'll likely be back here with questions for the forums collective experience. Live in the Santa Cruz Mts and sure could use a little work horse like this quad to haul stuff up and down my steep property. Thanks in advance.
Hope you all have a great Thanksgiving!
Just joined about a week ago since i recently bought a 2001 Yamaha Big Bear 400 4x4
We have also had a 2000 Honda Recon for about 10 years
Live in southeast Geriga and use them mostly on the property as work horses and the kids and grandkids to ride
I am sure i will have lots of questions of maintenance and upgrades,,,
looks like a great place for it!
Has anyone had experience installing an in-line water heater? It gets to -20 F here in the mountains and I had problems last winter. It looks like they get spliced into the coolant hose. Runs off of 120v and has internal circulation pump.
