Polaris trouble codes

Your engine codes should only be in two digit numbers and you should not have codes that end with any zeros.check engine light should flash like count the flashes three flashes pause then 6 flashes would be code 36 then longer pause between codes then you have more than one code after a long pause it may flash 4 times then short pause then two flashes would be code 42 witch is engine coolent temperature high voltage a code 56 is fuel pump open load/short to battery or short to ground should start with one flash short pause then two flash meaning 12 then codes will repeat ,to start flash engine codes turn key off and on three times in less then 5 sec then leave on

try resetting codes by removing both battery cables then touch them together away from battery terminals. then reconnect cables and start to see if it has same codes. not a valid code according to polaris code list

FROM THE WEB>>> Code 27 is "TPS SET ERROR"..take it to the dealer. Throttle Position Sensor reading is off...the newer models check the TPS reading at a startup..and set that as a baseline...if the reading is outside the normal range it throws the code. Try not to touch the gas pedal when starting.

P16A8 This Trouble Code sets if the Injector Output Supply 2 Voltage is below an acceptable limit. Can be caused by Damaged Wiring or Faulty/Shorted Connectors.
ECU Output Supply Voltage

Have the system scanned and find out what the fault code is for that was set when the light came on, that is how it is diagnosed

clean out the carb first

168 is a High Voltage. If it continues you may be having a voltage regulator about to or already gone bad.

The Machine is new, do you have a warranty? Has the machine been sitting for a while? If so, a professional carb/fuel system cleaning and a new spark plug should take care of it.

I WOULD take it o the dealer and find out what the code means!!
