that your speed sensor is miscounting
at low speed. To check your error codes,
look at P45 of your owners’ manual.
The sequence is outlined below if
you don’t have an owners’ manual:
1. If the error codes are not
displayed, use the Mode button
to toggle until “CK ENG” displays
on the main line of the display.
2. Press and hold the Mode button
to enter the diagnostics code menu.
3. Record the three numbers
displayed in the gear position,
clock and odometer displays.
4. Press the Mode button to
advance to the next error code.
5. Press and hold the Mode button
to exit the diagnostics code menu.
With the codes in hand, you need
to refer to P4.36 of the factory service
manual ( https://www.scribd.com/
manual) for the trouble code reference
chart for the 2015–2017 models.
With the chart and your codes, you
now have a chance to diagnose
the problem yourself. Good luck!
UP & DOWN IDLE ISSUES
I have a 2013 Polaris Ranger 800 EFI.
On starting, the idle raises up and stays
like that for a minute, but then lowers
down and smooths out. Any ideas
on what could cause this? Thanks.
Of all the idle problems the 800 EFIs
have had, yours is a bit different. First
thing I would check is your throttle plate
to see if it is bottoming out on the stop
screw and not hanging up in the throttle
body. If it is hanging up, that is the
cause of your high idling problem. The
fix is gently tapping the butterfly shaft
with a hammer to shift it into the center
of the bore. The other thing to try is to
adjust the TPS sensor yourself. You will
need a RZR idle speed adjustment tool

BY A RANCHER
I just bought a 2014 Honda
420 Rancher. When riding it, the
engine light began flashing “ 23.”
I changed the sensor, but it still
keeps flashing. What should I do?
Well, we first need to determine
which light you are referring to. An
“engine light” really means nothing to
me rather than some random indicator
light that you can see, blinks two times
slow and then three times fast! If a “ 23”
code is coming from the maintenance
indicator (wrench), that means a faulty
O2 sensor. However, if the code comes
from the gear indicator, then that is
a faulty shift angle sensor. There is
the chance you have confused the
indicators and replaced the wrong
sensor! If, on the other hand, you read
the indicator correctly and replaced
the correct sensor, there still could
be a problem with the wiring. Either a
corroded connection or a broken wire
is not allowing the sensor to be read by
the computer and could be driving the
flashing indicator. Either way, you should
have a service manual. If you are signed

GETTING FLASHED BY A RANGER
I recently purchased a used 2015
Ranger 570 FS with 712 miles from
a local dealer. When riding it on my
property, the engine light comes on at
low speeds— 3 to 5 mph. When I pick
up speed, it goes out. I took it back to
the dealer where they ran a diagnostic.
It showed 12 recorded incidents on the
computer but could give no explanation.
They wiped it from the memory, rode
two miles and claimed they could not
get it to light up. I have put 40 miles
on it and the light has come on a
dozen more times. Any info you might
have would be greatly appreciated.
Rusty, my boy, I wish you had shared
the 12 recorded incidents so I would
know what codes were thrown. My
guess, and this is just a wild guess, is

KMS Performance ( 442-4340).
Note the TPS adjustment tool comes
with a VOM meter if you don’t have one.
If you have one, select “no multi-meter”
to deduct $5. The KMS simplified TPS
adjustment instructions are here:
Note that when working with the
TPS, you may encounter broken wires
because the wrong type of wire was
spec’d out. Polaris has a repair kit for this
problem. Google “ Polaris 2878498” for
their kit harness and TPS throttle position
sensor pigtail connector wires. It is sold
on eBay and various Internet retailers.
XPT SHEAVES GROOVING OUT
I have a 2016 Polaris XP Turbo with
only 106 miles. Got a great deal on it.
The original owner never rode it after
one flip. Well, anyway, the clutch started
acting up, and when I took the CVT
cover off, I saw deep score marks on
the aluminum on the primary where the
sliders rub. It is long out of warranty,
so should I look at the aftermarket to
fix this or replace the OEM parts?
Actually, I would recommend
both! First, notify Polaris you have an
unmodified 2016 Turbo and you need
the 2017 CVT upgrade under warranty.
Second, contact Wolfsnout and order
their CVT pre-filter to keep sand out
of the CVT: https://wolfsnout.net/
shop/utv-accessories/utv-dust-clutch-filter/. If cleaned regularly, it will filter
out an amazing amount of stuff that
would otherwise get into the CVT
that causes CVT and belt wear. ❏
